Worked practice questions

As per your syllabus, the WORK-ENERGY theorem states that net work done equals which quantity?

  1. Change in potential energy
  2. Change in displacement
  3. Change in momentum
  4. Change in kinetic energy ΔK
Show answer and solution

Correct answer: D. Change in kinetic energy ΔK

Your syllabus: W_net = ΔK = K_f − K_i. Holds for both constant and variable forces.

As per your syllabus, the work done by a VARIABLE force F(x) over displacement from x_i to x_f is which?

  1. ∫ F(x) dx from x_i to x_f
  2. Area only of triangle
  3. F(x_f) × x_f − F(x_i) × x_i
  4. F(x_f) − F(x_i)
Show answer and solution

Correct answer: A. ∫ F(x) dx from x_i to x_f

Your syllabus: W = ∫ F(x) dx. Area under the F vs x curve.

As per your syllabus, is there an associated POTENTIAL ENERGY for FRICTION?

  1. Yes, V_friction = μ N x linearly
  2. Only for static friction case
  3. No, friction is non-conservative
  4. Yes, V = (1/2) μ N x² parabolic
Show answer and solution

Correct answer: C. No, friction is non-conservative

syllabus Points 8: friction is non-conservative (path-dependent W, closed-loop W ≠ 0). No PE function exists.
