Physics flashcards for AMUEEE

24 of 89 cards from the Physics deck — real questions with worked answers.

1. State the principle of homogeneity of dimensions.

   In any physically valid equation, every term on both sides must have the same dimensions. Only quantities with identical dimensions can be added, subtracted, or equated.

2. What are the dimensional formulae of force, work/energy, and power?

   Force: [M L T^-2]; Work/Energy: [M L^2 T^-2]; Power: [M L^2 T^-3].

3. Define absolute, relative, and percentage error.

   Absolute error = |true value - measured value|; Relative error = absolute error / true value; Percentage error = relative error x 100%.

4. How do errors combine in multiplication/division of measured quantities?

   The relative (or percentage) errors add. For Z = A^a B^b / C^c, the fractional error is ΔZ/Z = a(ΔA/A) + b(ΔB/B) + c(ΔC/C).

5. What are the three equations of motion for uniform acceleration?

   v = u + at; s = ut + ½at^2; v^2 = u^2 + 2as, where u = initial velocity, v = final velocity, a = acceleration, s = displacement.

6. For projectile motion launched at angle θ with speed u, give the time of flight, maximum height, and horizontal range.

   Time of flight T = 2u sinθ / g; Maximum height H = u^2 sin^2θ / 2g; Range R = u^2 sin2θ / g (maximum at θ = 45°).

7. Distinguish between distance and displacement.

   Distance is the total path length travelled (scalar, always ≥ 0); displacement is the shortest straight-line vector from initial to final position (vector, can be zero or negative).

8. 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 = dp/dt = ma. 3rd: Every action has an equal and opposite reaction.

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

   Impulse = F·Δt (the product of force and time, equal to area under F-t graph). Impulse-momentum theorem: impulse equals the change in momentum, J = Δp = m(v - u).

10. Give the conditions and formulae for static and kinetic friction.

    Limiting static friction f_s ≤ μ_s N (acts up to a maximum μ_s N); kinetic friction f_k = μ_k N (constant during sliding). Generally μ_s > μ_k.

11. For a body on a banked curve (frictionless), what is the relation for the ideal speed?

    tanθ = v^2 / (r g), so the ideal speed v = √(r g tanθ), where θ is the banking angle and r is the radius.

12. State the work-energy theorem.

    The net work done by all forces on a body equals the change in its kinetic energy: W_net = ΔKE = ½mv^2 - ½mu^2.

13. Distinguish between conservative and non-conservative forces.

    Conservative forces (e.g. gravity, spring) do work independent of path and zero over a closed loop; potential energy can be defined. Non-conservative forces (e.g. friction) depend on path and dissipate energy.

14. Define the coefficient of restitution and give its values for elastic and perfectly inelastic collisions.

    e = (relative velocity of separation)/(relative velocity of approach). e = 1 for perfectly elastic, e = 0 for perfectly inelastic, 0 < e < 1 for real collisions.

15. Give the spring potential energy and the power delivered by a constant force.

    Spring PE = ½kx^2 (k = spring constant, x = extension). Power P = W/t = F·v (dot product of force and velocity).

16. Define torque and moment of inertia.

    Torque τ = r x F = rF sinθ (rotational analogue of force). Moment of inertia I = Σ m_i r_i^2 (rotational analogue of mass, measures resistance to angular acceleration).

17. State the moment of inertia of a solid sphere, solid cylinder/disc, and a thin rod about a central axis.

    Solid sphere (about diameter): (2/5)MR^2; Solid cylinder/disc (about central axis): (1/2)MR^2; Thin rod (about centre, perpendicular): (1/12)ML^2.

18. State the parallel axis theorem and the perpendicular axis theorem.

    Parallel axis: I = I_cm + Md^2. Perpendicular axis (planar bodies only): I_z = I_x + I_y.

19. Write the rotational analogues of Newton's second law, kinetic energy, and angular momentum.

    τ = Iα; Rotational KE = ½Iω^2; Angular momentum L = Iω. Conservation: if τ_ext = 0, L is constant.

20. State Newton's law of universal gravitation and the value of G.

    F = G m1 m2 / r^2, directed along the line joining the masses. G = 6.67 x 10^-11 N·m^2/kg^2.

21. Give the formulae for orbital velocity and escape velocity from a planet of mass M and radius R.

    Orbital velocity v_o = √(GM/R) (at surface). Escape velocity v_e = √(2GM/R) = √2 · v_o ≈ 11.2 km/s for Earth.

22. State Kepler's three laws of planetary motion.

    1st (Orbits): planets move in ellipses with the Sun at one focus. 2nd (Areas): the line joining planet and Sun sweeps equal areas in equal times. 3rd (Periods): T^2 ∝ a^3.

23. How does acceleration due to gravity vary with height and depth?

    At height h: g_h = g(1 - 2h/R) for h << R. At depth d: g_d = g(1 - d/R). g is maximum at the surface and zero at the centre.

24. Define stress, strain, and Young's modulus.

    Stress = force/area (N/m^2); Strain = change in dimension / original dimension (dimensionless); Young's modulus Y = longitudinal stress / longitudinal strain.
