Worked practice questions

Rolling on the ground after a jump protects your bones by extending the:

  1. Speed of landing
  2. Time the force acts
  3. Height of the jump
  4. Mass of your body
Show answer and solution

Correct answer: B. Time the force acts

1. Landing stiff-legged gives a huge force. 2. Rolling spreads the stop over more time. 3. Parachutists do the same. _Source: OpenStax College Physics for AP Courses 2e, Chapter 8, Linear Momentum and Collisions (CC BY 4.0)._

On a force-versus-time graph, the area under the curve equals the:

  1. Inertia
  2. Density
  3. Impulse
  4. Velocity
Show answer and solution

Correct answer: C. Impulse

1. The area has units of momentum. 2. It equals the impulse or change in momentum. 3. An effective force gives the same area. _Source: OpenStax College Physics for AP Courses 2e, Chapter 8, Linear Momentum and Collisions (CC BY 4.0)._

When a football player hits a goalpost, momentum is still conserved because the Earth also:

  1. Spins
  2. Warms
  3. Shrinks
  4. Recoils
Show answer and solution

Correct answer: D. Recoils

1. The force on the post is passed to the Earth. 2. The Earth recoils immeasurably. 3. Total momentum stays constant. _Source: OpenStax College Physics for AP Courses 2e, Chapter 8, Linear Momentum and Collisions (CC BY 4.0)._
