# 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?

• BDoubling the velocity
• CBoth changes would increase the kinetic energy equally.

Q4:

An object that is moving decreases in velocity. Which of the following correctly describes how the kinetic energy changes for the object?

• AThe kinetic energy does not change.
• BThe kinetic energy increases.
• CThe kinetic energy decreases.

Q5:

An object that is moving increases in velocity. Which of the following correctly describes how the object’s kinetic energy changes?

• AThe kinetic energy decreases.
• BThe kinetic energy increases.
• CThe kinetic energy does not change.

Q6:
