BP! Kinetic Energy

When does an object have no kinetic energy?

• When the only force that's acting on it is gravity.

• When it's moving very slowly.

• When it has no electrical charge.

• When it's at rest.

• A 6 pound rolling bowling ball

• A 10 pound rolling bowling ball

• A 6 pound not moving bowling

• A 2 pound rolling bowling ball
