# Lesson Worksheet: Kinetic Energy Science

In this worksheet, we will practice determining the energy for an object due to motion of the object.

**Q1: **

A blue ball and a green ball move the same distance in a straight line for the same amount of time. The green ball has a greater mass. Which of the following correctly relates the kinetic energies for the balls?

- AThe kinetic energy for the blue ball is greater.
- BThe kinetic energy for the green ball is greater.
- CThe kinetic energy is the same for both balls.

**Q2: **

A blue ball and a green ball have the same mass. Each ball moves in a straight line for the same amount of time, but the blue ball moves further. Which of the following correctly relates the kinetic energies for the balls?

- AThe kinetic energy is the same for both balls.
- BThe kinetic energy for the blue ball is greater.
- CThe kinetic energy for the green ball is greater.

**Q3: **

What would increase the kinetic energy of an object more, doubling the mass of the object or doubling the velocity of the object?

- ADoubling the mass
- BDoubling the velocity
- CBoth changes would increase the kinetic energy equally.

**Q4: **
