Draw

Circle where the runner will be generating force to move.

• Potential Energy (PE)
  
  

• Kinetic Energy (KE)

​Two Types of Energy

The ability to MOVE or CHANGE matter in some way.

The ability to do WORK.

Science Definition

What is Energy?

Multiple Choice

The ability to do work comes from:

• Work

• Force

• Energy

• Gravity

STORED energy

or

Energy that is ready to be released.

​

Potential Energy

Energy that is released

or

Energy in motion

​

Kinetic Energy

Match

Match the following terms to the correct definition

• Kinetic Energy

• Potential Energy

• Work

• Force

Energy in motion

Stored energy

Force that causes motion

A push or pull

• Energy in motion

• Stored energy

• Force that causes motion

• A push or pull

​These Pandas are close to the ground. It did not take a lot of work to get there, so they have very little PE.

​​Less Potential Energy

This car needed a lot of energy to get to the top of the hill. That means this car as a lot of PE.

More Potential Energy

​How does position affect PE?

​The more massive an object is, the more work is required to move it.

The more work required to move an object - the more PE an object has.

​

Potential Energy and Size

Labelling

​ Label the oranges with the correct label that says how much Potential Energy they have.

Drag labels to their correct position on the image

Least

Middle

Most

Hotspot

Click on where the rollercoaster has the MOST potential energy.

Any moving object has Kinetic Energy

The faster an object is moving, the more Kinetic Energy it has.

The more massive an object, the more KE it has

​

How does Kinetic Energy Work?

Kinetic Energy Formula

Yes! Objects in motion can have a mix of PE and KE

Can something have both PE and KE?

​

​As the ball rolls down the hill, PE is converted into KE. While in the middle of the hill, the ball has BOTH!
