Worked practice questions

Squids propel themselves like jellyfish and typically move at:

  1. 80 to 90 km/h
  2. 8 to 12 km/h
  3. 1 to 2 km/h
  4. 50 to 60 km/h
Show answer and solution

Correct answer: B. 8 to 12 km/h

1. They push water out and move the other way. 2. Typical speed is 8 to 12 km/h. 3. It is momentum conservation. _Source: OpenStax College Physics for AP Courses 2e, Chapter 8, Linear Momentum and Collisions (CC BY 4.0)._

A collision that conserves internal kinetic energy is called:

  1. Explosive
  2. Sticking
  3. Elastic
  4. Inelastic
Show answer and solution

Correct answer: C. Elastic

1. Momentum is conserved in both types. 2. Elastic also conserves kinetic energy. 3. Inelastic collisions change kinetic energy. _Source: OpenStax College Physics for AP Courses 2e, Chapter 8, Linear Momentum and Collisions (CC BY 4.0)._

Truly elastic collisions are achieved only with:

  1. Steel blocks on ice
  2. Carts with springs
  3. Billiard balls
  4. Subatomic particles
Show answer and solution

Correct answer: D. Subatomic particles

1. Macroscopic collisions lose some energy to heat and sound. 2. Only subatomic particles collide truly elastically. 3. Steel on ice is nearly elastic. _Source: OpenStax College Physics for AP Courses 2e, Chapter 8, Linear Momentum and Collisions (CC BY 4.0)._
