20 of 51 cards from the Physics - Mechanics and Thermal Physics deck — real questions with worked answers.

1. What is a dimensional formula, and what is the dimensional formula of force?

   A dimensional formula expresses a physical quantity in terms of base quantities (M, L, T, etc.). Force = mass x acceleration, so its dimensional formula is [M L T^-2].

2. State the principle of homogeneity of dimensions.

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

3. Differentiate between accuracy and precision in measurement.

   Accuracy is how close a measured value is to the true value. Precision is how close repeated measurements are to one another (reproducibility), regardless of the true value.

4. How do you determine the number of significant figures, and how many are in 0.00430?

   Significant figures are all certain digits plus one estimated digit; leading zeros are not significant, trailing zeros after a decimal are. 0.00430 has 3 significant figures (4, 3, 0).

5. What are the three equations of motion for uniformly accelerated motion?

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

6. Define instantaneous velocity and instantaneous acceleration.

   Instantaneous velocity is the rate of change of displacement at an instant: v = ds/dt. Instantaneous acceleration is the rate of change of velocity at an instant: a = dv/dt = d^2s/dt^2.

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

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

8. At what projection angle is the horizontal range of a projectile maximum, and what is that range?

   Range is maximum at theta = 45 degrees. Maximum range R_max = u^2/g.

9. What is the relationship between linear velocity, angular velocity, and radius in uniform circular motion?

   v = r omega, where v is linear (tangential) speed, omega is angular velocity, and r is the radius of the circular path.

10. Give the formula for centripetal acceleration in uniform circular motion.

    a_c = v^2/r = r omega^2, directed toward the center of the circle.

11. State Newton's three laws of motion.

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

12. What is impulse, and how is it related to momentum?

    Impulse = Force x time = F*delta_t. By the impulse-momentum theorem, impulse equals the change in linear momentum: F*delta_t = delta_p = m(v - u).

13. State the law of conservation of linear momentum.

    If no net external force acts on a system, its total linear momentum remains constant: m1*u1 + m2*u2 = m1*v1 + m2*v2.

14. Differentiate static friction, limiting friction, and kinetic friction.

    Static friction is the self-adjusting opposing force on a stationary body (0 to a maximum). Limiting friction is the maximum static friction (f = mu_s*N). Kinetic friction acts on a moving body (f = mu_k*N), and mu_k < mu_s.

15. For a body on a banked curve (frictionless), what is the safe speed?

    v = sqrt(r g tan(theta)), where theta is the banking angle, r is the radius, and g is gravitational acceleration.

16. 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.

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

    Power is the rate of doing work: P = W/t. Instantaneously, P = F . v (dot product of force and velocity). SI unit: watt (W).

18. Distinguish 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; in a perfectly inelastic collision the bodies stick together.

19. What is the formula for elastic potential energy stored in a stretched spring?

    U = (1/2)k x^2, where k is the spring constant and x is the displacement from the natural (equilibrium) length.

20. Define the coefficient of restitution.

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