NED Admission Test Physics flashcards — 50 questions with answers

  1. What is a physical quantity?

    A measurable property of a physical system that can be expressed as a numerical value multiplied by a unit (e.g., length = 5 m).

  2. What are base (fundamental) quantities in the SI system, and how many are there?

    Seven base quantities, each independent of the others: length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

  3. List the seven SI base units with their symbols.

    Metre (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd).

  4. What is the difference between base quantities and derived quantities?

    Base quantities are independent and defined directly (e.g., length, mass, time). Derived quantities are obtained by combining base quantities through multiplication/division (e.g., velocity = length/time, force = mass×acceleration).

  5. Define a supplementary SI unit and give examples.

    Supplementary units are dimensionless geometric units: the radian (rad) for plane angle and the steradian (sr) for solid angle.

  6. What is the SI unit of force, and express it in base units.

    The newton (N). In base units, 1 N = 1 kg·m·s⁻².

  7. What is the SI unit of energy and work, and express it in base units.

    The joule (J). 1 J = 1 N·m = 1 kg·m²·s⁻².

  8. What is the dimension of a physical quantity?

    The dimension expresses how a quantity relates to the base quantities, written using symbols such as [L] for length, [M] for mass, [T] for time, [I] for current, and [θ] for temperature.

  9. Write the dimensional formula for velocity, acceleration, and force.

    Velocity: [LT⁻¹]; Acceleration: [LT⁻²]; Force: [MLT⁻²].

  10. Write the dimensional formula for work/energy and power.

    Work/Energy: [ML²T⁻²]; Power: [ML²T⁻³].

  11. State the principle of homogeneity of dimensions.

    Every term on both sides of a physically correct equation must have the same dimensions; only quantities with identical dimensions can be added or equated.

  12. What are the main uses of dimensional analysis?

    To check the dimensional correctness of an equation, to derive relationships between physical quantities, and to convert units from one system to another.

  13. What is a key limitation of dimensional analysis?

    It cannot determine dimensionless constants (like ½ or 2π), cannot handle equations with more than three unknown quantities easily, and cannot check trigonometric, exponential, or logarithmic relations.

  14. Verify the dimensional correctness of v = u + at.

    v: [LT⁻¹], u: [LT⁻¹], at: [LT⁻²][T] = [LT⁻¹]. All terms are [LT⁻¹], so the equation is dimensionally consistent.

  15. What is the difference between systematic and random errors?

    Systematic errors are consistent and repeatable (due to faulty instruments, zero error, or method), shifting results in one direction. Random errors are unpredictable fluctuations and can be reduced by averaging many readings.

  16. Define absolute error, relative error, and percentage error.

    Absolute error = |measured − true value|. Relative error = absolute error / true value. Percentage error = relative error × 100%.

  17. What is the difference between accuracy and precision?

    Accuracy is how close a measurement is to the true value; precision is how close repeated measurements are to each other (reproducibility). A set can be precise but inaccurate.

  18. What are significant figures?

    The digits in a measurement that carry meaningful information, including all certain digits plus the first uncertain (estimated) digit.

  19. State the rules for counting significant figures regarding zeros.

    Leading zeros are not significant (0.0025 → 2 s.f.); zeros between non-zero digits are significant (1002 → 4 s.f.); trailing zeros after a decimal point are significant (2.50 → 3 s.f.).

  20. How do significant figures combine in multiplication/division versus addition/subtraction?

    In multiplication/division, the result has as many significant figures as the factor with the fewest. In addition/subtraction, the result has as many decimal places as the term with the fewest decimal places.

  1. How do errors propagate when quantities are multiplied or divided?

    The relative (percentage) errors add. For Z = AB or A/B, (ΔZ/Z) = (ΔA/A) + (ΔB/B).

  2. What is a scalar quantity and a vector quantity? Give one example of each.

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

  3. State the head-to-tail (polygon) rule for vector addition.

    Place the tail of each successive vector at the head of the previous one; the resultant is drawn from the tail of the first vector to the head of the last.

  4. State the parallelogram law of vector addition.

    If two vectors are represented by the adjacent sides of a parallelogram drawn from a common point, their resultant is given by the diagonal of the parallelogram from that point.

  5. Give the formula for the magnitude of the resultant of two vectors A and B with angle θ between them.

    R = √(A² + B² + 2AB·cosθ).

  6. How do you resolve a vector A into rectangular components in 2D?

    Aₓ = A·cosθ (horizontal) and Aᵧ = A·sinθ (vertical), where θ is the angle measured from the x-axis.

  7. How do you find the magnitude and direction of a vector from its components Aₓ and Aᵧ?

    Magnitude A = √(Aₓ² + Aᵧ²); Direction θ = tan⁻¹(Aᵧ/Aₓ) measured from the x-axis.

  8. What are the maximum and minimum possible resultants of two vectors of magnitudes A and B?

    Maximum = A + B (when they are parallel, θ = 0°); Minimum = |A − B| (when they are antiparallel, θ = 180°).

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

    v = u + at; s = ut + ½at²; v² = u² + 2as, where u = initial velocity, v = final velocity, a = acceleration, s = displacement, t = time.

  10. What is the difference between distance and displacement?

    Distance is the total path length travelled (scalar, always positive). Displacement is the straight-line change in position from start to finish (vector, with direction).

  11. What is the difference between speed and velocity?

    Speed is the rate of change of distance (scalar). Velocity is the rate of change of displacement (vector, with direction).

  12. What is the displacement of a freely falling body, and what value of acceleration is used?

    For free fall: s = ½gt² (starting from rest), using acceleration g ≈ 9.8 m/s² directed downward (air resistance neglected).

  13. How is distance found from a velocity–time graph?

    The distance (or displacement) travelled equals the area under the velocity–time graph.

  14. What does the slope (gradient) of a velocity–time graph represent?

    The slope of a velocity–time graph represents acceleration.

  15. What is projectile motion and what are its two independent components?

    Projectile motion is two-dimensional motion under gravity alone. It has a horizontal component with constant velocity (zero acceleration) and a vertical component with constant downward acceleration g; the two are independent.

  16. Write the formulas for time of flight, maximum height, and range of a projectile launched at angle θ with speed u.

    Time of flight T = (2u·sinθ)/g; Maximum height H = (u²·sin²θ)/(2g); Range R = (u²·sin2θ)/g.

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

    The range is maximum at θ = 45°, where R_max = u²/g.

  18. What is the shape of a projectile's trajectory and the velocity at maximum height?

    The trajectory is a parabola. At maximum height the vertical velocity is zero and only the horizontal component (u·cosθ) remains.

  19. Define relative velocity.

    The relative velocity of object A with respect to object B is the velocity of A as observed from B: v_AB = v_A − v_B (vector subtraction).

  20. Two cars move in the same direction at velocities v₁ and v₂. What is their relative velocity?

    v_rel = v₁ − v₂ (the difference), since they move in the same direction.

  21. Two cars move toward each other at velocities v₁ and v₂. What is their relative velocity of approach?

    v_rel = v₁ + v₂ (the magnitudes add), because they move in opposite directions.

  22. State Newton's First Law of Motion.

    A body remains at rest or in uniform motion in a straight line unless acted upon by a net external force (the law of inertia).

  23. State Newton's Second Law of Motion and its equation.

    The rate of change of momentum of a body is directly proportional to the applied force and in its direction: F = ma (or F = dp/dt).

  24. State Newton's Third Law of Motion.

    For every action there is an equal and opposite reaction; the forces act on two different bodies.

  25. Define inertia and state what it depends on.

    Inertia is the tendency of a body to resist any change in its state of rest or uniform motion. It depends on (is measured by) the body's mass.

  26. Define linear momentum and give its SI unit.

    Linear momentum is the product of a body's mass and velocity: p = mv. It is a vector, with SI unit kg·m·s⁻¹ (equivalent to N·s).

  27. Define impulse and state its relationship to momentum.

    Impulse is the product of force and the time for which it acts: J = F·Δt. The impulse–momentum theorem states impulse equals the change in momentum: F·Δt = Δp = m(v − u).

  28. State the law of conservation of linear momentum.

    If no net external force acts on a system, its total linear momentum remains constant: total momentum before = total momentum after an interaction.

  29. 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/deformation); in a perfectly inelastic collision the bodies stick together.

  30. Define work done by a force, give its formula and condition for zero work.

    Work = force × displacement in the direction of the force: W = F·s·cosθ. Work is zero when θ = 90° (force perpendicular to displacement) or when displacement is zero. SI unit: joule (J).
