PE & KE Formative

Energy is...

• the ability to cause change or do work.

• anything that has mass and takes up space.

• always in motion.

• strength or power exerted on an object.

What is true about PE and KE?

• There is always more PE in a system.

• The systems uses up PE first, then switches to kinetic energy.

• There is always more kinetic energy in a system.

• The total of PE and KE is equal. Energy is never created or destroyed.

• There is an unlimited amount of energy on Earth. We can never run out.
