Worked practice questions

Linear momentum is defined as a system's mass multiplied by its:

  1. Velocity
  2. Acceleration
  3. Displacement
  4. Temperature
Show answer and solution

Correct answer: A. Velocity

1. Momentum captures both how much matter is moving and how fast. 2. Linear momentum is defined as the product of a system's mass multiplied by its velocity. 3. Because velocity is a vector, momentum is a vector too. 4. Acceleration and displacement are different quantities entirely. _Source: OpenStax College Physics for AP(R) Courses 2e (CC BY 4.0), Ch 8 'Linear Momentum and Collisions', sections 8.1-8.7_

Newton stated his second law in terms of momentum, calling momentum the:

  1. Quantity of force
  2. Quantity of motion
  3. Quantity of matter
  4. Quantity of energy
Show answer and solution

Correct answer: B. Quantity of motion

1. The importance of momentum was recognised early in the development of classical physics. 2. It was recognised much earlier than the importance of energy. 3. Momentum was deemed so important that it was called the quantity of motion. 4. Newton actually stated his second law of motion in terms of momentum. _Source: OpenStax College Physics for AP(R) Courses 2e (CC BY 4.0), Ch 8 'Linear Momentum and Collisions', sections 8.1-8.7_

Stated in terms of momentum, Newton's second law says net external force equals change in momentum divided by:

  1. The distance moved
  2. The velocity gained
  3. The time it takes
  4. The mass involved
Show answer and solution

Correct answer: C. The time it takes

1. Force acting over time can change momentum. 2. The net external force equals the change in momentum of a system divided by the time over which it changes. 3. This is the most broadly applicable form of the second law. 4. Dividing by mass would give an acceleration rather than a force. _Source: OpenStax College Physics for AP(R) Courses 2e (CC BY 4.0), Ch 8 'Linear Momentum and Collisions', sections 8.1-8.7_
