When it is rolling quickly down a tall, steep hill.

Front

How does energy change when a player kicks a soccer ball?

Back

The ball gains most of the energy of motion.

Front

What is the relationship between speed and energy?

Back

Faster objects have more energy than slower ones if mass is constant.

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is potential energy?

Back

Potential energy is stored energy based on position.

Front

How can energy be transferred?

Back

Energy can be transferred through actions like pushing or pulling.
