Physics flashcards for AKU MBBS Admission Test

24 of 61 cards from the Physics deck — real questions with worked answers.

1. In kinematics, what is the difference between distance and displacement?

   Distance is the total path length travelled (a scalar, always positive). Displacement is the straight-line change in position from start to end, with direction (a vector); its magnitude can be less than or equal to distance.

2. State the three equations of motion for uniform acceleration.

   v = u + at; s = ut + (1/2)at^2; v^2 = u^2 + 2as, where u = initial velocity, v = final velocity, a = acceleration, t = time, s = displacement.

3. For a body in free fall (ignoring air resistance), what is its acceleration and does it depend on mass?

   It accelerates downward at g (about 9.8 m/s^2 on Earth), independent of mass; all bodies fall at the same rate in a vacuum.

4. For projectile motion, what are the horizontal and vertical acceleration components?

   Horizontal acceleration is zero (constant horizontal velocity); vertical acceleration equals g downward. The two motions are independent.

5. What are the formulas for the time of flight, maximum height, and range of a projectile launched at angle theta with speed u?

   Time of flight T = 2u sin(theta)/g; Maximum height H = u^2 sin^2(theta)/(2g); Range R = u^2 sin(2theta)/g. Maximum range occurs at theta = 45 degrees.

6. State Newton's First Law of Motion (law of inertia).

   A body remains at rest or in uniform motion in a straight line unless acted upon by a net external force. This property of resisting change in motion is called inertia.

7. State Newton's Second Law of Motion and its formula.

   The rate of change of momentum of a body is proportional to the applied net force and occurs in the direction of the force: F = dp/dt = ma (for constant mass).

8. State Newton's Third Law of Motion.

   For every action there is an equal and opposite reaction; the action and reaction forces act on two different bodies and are equal in magnitude, opposite in direction.

9. What is the difference between mass and weight?

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

10. Define the coefficient of friction and write the formula for limiting friction.

    The coefficient of friction (mu) is the ratio of the limiting frictional force to the normal reaction: mu = F/R, so limiting friction F = mu R. It is dimensionless.

11. Define work in physics and give its formula and SI unit.

    Work is done when a force moves its point of application along its direction: W = F s cos(theta), where theta is the angle between force and displacement. SI unit is the joule (J) = N·m.

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

    Kinetic energy KE = (1/2)mv^2; gravitational potential energy PE = mgh (near Earth's surface).

13. State the work-energy theorem.

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

14. Define power and give two formulas for it.

    Power is the rate of doing work: P = W/t. It also equals P = F·v (force times velocity). SI unit is the watt (W) = J/s.

15. State the law of conservation of energy.

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

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

    Linear momentum p = mv (a vector). In the absence of an external force, the total momentum of an isolated system remains constant before and after interaction.

17. Define impulse and state the impulse-momentum theorem.

    Impulse = force × time = F·t, equal to the change in momentum: F·t = delta p = m(v - u). SI unit is N·s (or kg·m/s).

18. Compare 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.

19. In a one-dimensional elastic collision of two equal masses, one moving and one at rest, what happens?

    The moving body stops and transfers all its velocity to the stationary body; they exchange velocities.

20. Define centripetal acceleration and force for circular motion, with formulas.

    Centripetal acceleration a = v^2/r = omega^2 r, directed toward the center. Centripetal force F = mv^2/r = m omega^2 r, the net inward force needed to keep a body in a circular path.

21. Define angular velocity and relate it to linear velocity.

    Angular velocity omega = theta/t (rad/s) is the rate of change of angular displacement. Linear (tangential) velocity v = r omega, where r is the radius.

22. Define torque and write its formula.

    Torque (moment of force) is the turning effect of a force: tau = r F sin(theta) = r × F. SI unit is N·m. It causes angular acceleration.

23. Define moment of inertia and state its role in rotational motion.

    Moment of inertia I = sum of m r^2 is the rotational analogue of mass; it measures resistance to angular acceleration. Rotational form of Newton's second law: tau = I alpha.

24. State the law of conservation of angular momentum and define angular momentum.

    Angular momentum L = I omega (= mvr for a point mass). In the absence of external torque, total angular momentum is conserved; e.g., a spinning skater speeds up when pulling arms in (I decreases, omega increases).
