AKU BScN Admission Test Physics flashcards — 51 questions with answers

  1. What is the difference between a base (fundamental) quantity and a derived quantity? Give one example of each.

    A base quantity is independent and not defined in terms of others (e.g. length, mass, time). A derived quantity is formed by combining base quantities (e.g. velocity = length/time, force = mass x acceleration).

  2. List the seven SI base quantities and their units.

    Length (metre, m), Mass (kilogram, kg), Time (second, s), Electric current (ampere, A), Temperature (kelvin, K), Amount of substance (mole, mol), Luminous intensity (candela, cd).

  3. What is the dimensional formula of force, and how is it derived?

    Force = mass x acceleration = [M][L T^-2] = [M L T^-2].

  4. State the principle of homogeneity of dimensions and its main use.

    Every term on both sides of a physically correct equation must have the same dimensions. It is used to check the correctness of equations and to derive relationships between quantities.

  5. What are dimensionless quantities? Give two examples.

    Quantities with no dimensions (pure numbers or ratios). Examples: strain, refractive index, relative density, angle (radian), coefficient of friction.

  6. Distinguish between scalar and vector quantities, with one example of each.

    A scalar has only magnitude (e.g. mass, temperature, speed, energy). A vector has both magnitude and direction (e.g. displacement, velocity, force, momentum).

  7. State the head-to-tail (triangle) rule for adding two vectors.

    Draw the first vector, then place the tail of the second vector at the head of the first; the resultant is the vector drawn from the tail of the first to the head of the second.

  8. For two vectors A and B with angle theta between them, what is the magnitude of their resultant?

    R = sqrt(A^2 + B^2 + 2AB cos theta).

  9. How do you find the rectangular components of a vector A at angle theta to the x-axis?

    Ax = A cos theta (horizontal component) and Ay = A sin theta (vertical component); magnitude A = sqrt(Ax^2 + Ay^2).

  10. Define the dot product and cross product of two vectors and state whether each is scalar or vector.

    Dot product A.B = AB cos theta (a scalar). Cross product A x B = AB sin theta (a vector, perpendicular to both, direction by right-hand rule).

  11. Distinguish between distance and displacement.

    Distance is the total path length travelled (scalar, always positive). Displacement is the shortest straight-line vector from initial to final position (vector, can be zero or negative).

  12. Write the three equations of motion for uniform acceleration.

    v = u + at; s = ut + (1/2)at^2; v^2 = u^2 + 2as.

  13. What is the difference between speed and velocity, and between average and instantaneous values?

    Speed is scalar (distance/time); velocity is vector (displacement/time). Average is over a finite interval; instantaneous is the value at a particular instant (limit as time interval approaches zero).

  14. For a projectile launched at angle theta with speed u, give the formulas for time of flight, maximum height, and range.

    Time of flight T = 2u sin theta / g; Maximum height H = u^2 sin^2 theta / (2g); Range R = u^2 sin 2theta / g.

  15. At what launch angle is the range of a projectile maximum, and what is that maximum range?

    At 45 degrees; maximum range R = u^2 / g.

  16. State Newton's three laws of motion.

    1st: A body stays at rest or in uniform motion unless acted on by a net external force (inertia). 2nd: F = ma (net force equals rate of change of momentum). 3rd: For every action there is an equal and opposite reaction.

  17. Define inertia and state which physical quantity measures it.

    Inertia is the tendency of a body to resist any change in its state of rest or motion. It is measured by the mass of the body.

  18. Distinguish between mass and weight, including units.

    Mass is the amount of matter in a body (scalar, kg, constant everywhere). Weight is the gravitational force on the body, W = mg (vector, newton, varies with g).

  19. What is the impulse of a force and how does it relate to momentum?

    Impulse = Force x time = F.t (vector, unit N.s). Impulse equals the change in momentum: F.t = m(v - u).

  20. Define the work done by a constant force, including the angle dependence.

    Work W = F.d cos theta, where theta is the angle between the force and displacement. Work is a scalar measured in joules (J).

  1. Write the formulas for kinetic energy and gravitational potential energy.

    Kinetic energy KE = (1/2)mv^2; Gravitational potential energy PE = mgh.

  2. State the work-energy theorem.

    The net work done on a body equals the change in its kinetic energy: W_net = KE_final - KE_initial = (1/2)mv^2 - (1/2)mu^2.

  3. Define power and give its formula in terms of work and in terms of force and velocity.

    Power is the rate of doing work. P = W/t and P = F.v. SI unit is the watt (W); 1 W = 1 J/s.

  4. State the law of conservation of energy.

    Energy can neither be created nor destroyed; it can only be transformed from one form to another, and the total energy of an isolated system remains constant.

  5. Define linear momentum and state the law of conservation of momentum.

    Linear momentum p = mv (vector, unit kg.m/s). For an isolated system (no external force) total momentum is conserved: total momentum before = total momentum after a collision.

  6. Distinguish between elastic and inelastic collisions.

    In an elastic collision both momentum and kinetic energy are conserved. In an inelastic collision momentum is conserved but kinetic energy is not (some converts to heat/sound); in a perfectly inelastic collision the bodies stick together.

  7. For a perfectly inelastic collision of masses m1 (speed u1) and m2 (at rest), what is the common final velocity?

    v = m1.u1 / (m1 + m2), since the bodies move together after collision.

  8. Define centripetal acceleration and give its formula.

    Centripetal acceleration is the acceleration directed toward the centre of a circular path. a = v^2 / r = r.omega^2.

  9. Write the formula for centripetal force and state its direction.

    Centripetal force F = mv^2 / r = m.r.omega^2, directed toward the centre of the circle.

  10. Define angular velocity and give its relationship to linear (tangential) velocity.

    Angular velocity omega is the rate of change of angular displacement (rad/s). It relates to linear velocity by v = r.omega, where r is the radius.

  11. State Newton's law of universal gravitation with its formula.

    Every two masses attract with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them: F = G m1 m2 / r^2, where G = 6.67 x 10^-11 N.m^2/kg^2.

  12. How does the acceleration due to gravity g relate to the Earth's mass and radius?

    g = G M / R^2, where M is the Earth's mass and R its radius. It decreases with altitude and with depth below the surface.

  13. Define escape velocity and give its formula for Earth.

    Escape velocity is the minimum speed needed to escape a planet's gravity without further propulsion. v_e = sqrt(2 G M / R) = sqrt(2 g R), about 11.2 km/s for Earth.

  14. What conditions define simple harmonic motion (SHM)?

    SHM occurs when the restoring force (or acceleration) is directly proportional to displacement from the equilibrium position and is always directed toward that position: a = -omega^2 x.

  15. Give the formulas for the time period of a simple pendulum and a mass-spring system.

    Simple pendulum: T = 2 pi sqrt(L/g). Mass-spring: T = 2 pi sqrt(m/k).

  16. In SHM, where are velocity and acceleration maximum and minimum?

    Velocity is maximum at the equilibrium (mean) position and zero at the extremes. Acceleration is maximum at the extreme positions and zero at the mean position.

  17. Define wavelength, frequency, and the wave equation relating them to speed.

    Wavelength (lambda) is the distance between successive identical points; frequency (f) is the number of waves per second. Wave speed v = f.lambda.

  18. Distinguish between transverse and longitudinal waves, with an example of each.

    In a transverse wave particles vibrate perpendicular to wave travel (e.g. light, waves on a string). In a longitudinal wave particles vibrate parallel to wave travel, forming compressions and rarefactions (e.g. sound).

  19. What is the difference between a node and an antinode in a standing wave?

    A node is a point of zero (minimum) displacement; an antinode is a point of maximum displacement. Adjacent nodes are separated by half a wavelength.

  20. Why can sound travel through solids, liquids and gases but not through a vacuum?

    Sound is a mechanical (longitudinal) wave requiring a material medium with particles to transmit vibrations. A vacuum has no particles, so sound cannot propagate through it.

  21. What is the approximate speed of sound in air, and how does it depend on the medium and temperature?

    About 340 m/s in air at room temperature. Sound travels fastest in solids, slower in liquids, slowest in gases; in air its speed increases with temperature.

  22. Define the Doppler effect.

    The Doppler effect is the apparent change in observed frequency (pitch) of a wave due to relative motion between the source and the observer; frequency increases as they approach and decreases as they recede.

  23. Distinguish between heat and temperature.

    Temperature is a measure of the average kinetic energy of particles (degree of hotness, measured in K or C). Heat is the energy transferred between bodies due to a temperature difference (measured in joules).

  24. Name the three modes of heat transfer and briefly describe each.

    Conduction: transfer through a solid by particle collisions without bulk movement. Convection: transfer in fluids by the actual movement of heated material. Radiation: transfer by electromagnetic waves, requiring no medium.

  25. Convert 27 degrees Celsius to kelvin and give the conversion formula.

    K = C + 273. So 27 C = 27 + 273 = 300 K.

  26. State the first law of thermodynamics with its equation.

    Energy is conserved: the heat added to a system equals the increase in internal energy plus the work done by the system. Delta Q = Delta U + W.

  27. State the second law of thermodynamics (one common statement).

    Heat cannot spontaneously flow from a colder body to a hotter body; equivalently, the entropy (disorder) of an isolated system tends to increase, and no heat engine can be 100% efficient.

  28. State Boyle's law and Charles's law for an ideal gas.

    Boyle's law: at constant temperature, P is inversely proportional to V (PV = constant). Charles's law: at constant pressure, V is directly proportional to absolute temperature T (V/T = constant).

  29. Write the ideal gas equation and identify each symbol.

    PV = nRT, where P = pressure, V = volume, n = number of moles, R = universal gas constant (8.31 J/mol.K), T = absolute temperature in kelvin.

  30. State Coulomb's law of electrostatic force with its formula.

    The force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them: F = k q1 q2 / r^2, where k = 9 x 10^9 N.m^2/C^2.

  31. State Ohm's law and give the formula relating voltage, current and resistance.

    At constant temperature, the current through a conductor is directly proportional to the potential difference across it: V = I R.
