Worked practice questions

In circular motion at radius r and speed v, the centripetal acceleration is:

  1. v/r
  2. v²/r
  3. r/v
  4. mv²
Show answer and solution

Correct answer: B. v²/r

a_centripetal = v²/r — directed toward the center. Alternatively, a = ω²r where ω is angular velocity. This is the acceleration required to keep the body on its circular path.

As per your syllabus, for a body of constant mass, the second law reduces to which form?

  1. F = m a
  2. F = m / a
  3. F = m × p
  4. F = m × v
Show answer and solution

Correct answer: A. F = m a

Your syllabus: F = d(mv)/dt = m dv/dt = m a (since m is constant).

As per your syllabus, the total momentum of an ISOLATED system (no external force) is which?

  1. Always increasing
  2. Always zero
  3. Only the speed is conserved
  4. Conserved
Show answer and solution

Correct answer: D. Conserved

Your syllabus: F_ext = 0 ⇒ dP_total/dt = 0 ⇒ P_total constant. Holds in any inertial frame valid for elastic AND inelastic collisions.
