Worked practice questions

A lab trolley of 2 kg rolls at 3 m/s. The quantity mass times velocity is called its:

  1. Momentum
  2. Mileage
  3. Moment
  4. Modulus
Show answer and solution

Correct answer: A. Momentum

1. Mass tells how much stuff is moving. 2. Velocity tells how fast it moves. 3. Their product is momentum. _Source: OpenStax University Physics Volume 1, Chapter 9, Linear Momentum and Collisions._

Two students argue about a word. Momentum comes from a Latin word that means:

  1. Mountain
  2. Movement
  3. Muscle
  4. Mixture
Show answer and solution

Correct answer: B. Movement

1. The idea is quantity of motion. 2. The Latin root movimentum names motion. 3. So the meaning is movement. _Source: OpenStax University Physics Volume 1, Chapter 9, Linear Momentum and Collisions._

A coach pushes a sled harder but for the same time. The sled's change in momentum:

  1. Rises
  2. Drops
  3. Stays
  4. Flips
Show answer and solution

Correct answer: A. Rises

1. A bigger push acts on the same sled. 2. More force in the same time means more change. 3. So the change in momentum rises. _Source: OpenStax University Physics Volume 1, Chapter 9, Linear Momentum and Collisions._
