What is the SI unit of acceleration?

  1. ms⁻²
  2. ms
  3. kg ms⁻¹
  4. ms⁻¹
Show answer and solution

Correct answer: A. ms⁻²

1. Acceleration is the rate of change of velocity with time. 2. Velocity is measured in metres per second (ms⁻¹). 3. Dividing by time again gives metres per second squared, ms⁻². _Source: RRB Group D CEN-02/2018 PYQ, Q.38._

Which of the following examples illustrates Newton's third law of motion?

  1. A sudden bus start jerks passengers backward
  2. A fielder pulls his hand back catching a ball
  3. The launching of a rocket into the sky
  4. A bicycle slows when we stop pedalling
Show answer and solution

Correct answer: C. The launching of a rocket into the sky

1. Newton's third law: every action has an equal and opposite reaction. 2. A rocket pushes gases downward (action) and is pushed upward (reaction). 3. The other options illustrate inertia or friction, not the third law. _Source: RRB Group D CEN-02/2018 PYQ, Q.35._
