Is the energy of motion

-car driving down road
- standing with muscles
- heart beating

Types of Kinetic Energy:
- electricity
- sound
- light
All created by movement!

​Kinetic Energy

Multiple Choice

Which of the following is the best example of kinetic energy?

• a bag of marbles on a table

• a picture hanging on a wall

• a ball rolling down a hill

• standing at the top of the stairs

Is stored energy or energy of position

- person at top of sliding board
- ball at top of stairs
- skateboarder at top of hill

​

​Potential Energy

Is a type of potential energy stored in molecules​

when atoms are rearranged it releases chemical energy

- food you eat
- gas in car


Potential Energy can become Kinetic Energy

​Chemical Energy

a change of energy from one form into another

occurs when energy moves from one object to another
OR
energy changes to a different type

​-> Consider the picture, what is occurring?

​Energy Transfer

• Hitting a golf ball with a club

• using food energy to exercise

• using a hot stove to cook food

• skateboarding

• skiing

• Hitting a baseball

​

Examples of Energy Transfer

Multiple Select

Which of the following are examples of energy transfers?

Choose more than one!

• a book on a bookshelf

• burning gasoline to power a car

• wind causing tree branches to sway

• boing water over a fire

States that energy cannot be created or destroyed

it can be converted to a new form but not destroyed

​

Law of Conservation of Energy

Multiple Choice

The roller coaster at the top of the hill has potential energy. What happens to that energy as the roller coaster goes down the hill?

• the coaster loses energy

• the energy is stored in the wheels for later use

• the energy changes form to kinetic energy

• the roller coaster gains energy

A system is a group of structures that work together.
Sometimes you need to add energy to a system to get the objects to do work.

Like Newton's cradle!

​

​System

Newton's Cradle

When the cat pulls ball upward, it has potential energy.

When the ball falls, the potential energy becomes kinetic energy.

When the first ball strikes the second, the energy transfers down the line.

Last ball uses kinetic energy to move upward and gains potential energy.

Energy transfers back and forth!

Poll

How do you feel about knowing the difference between kinetic and potential energy?

• I've go this!

• I think I understand.

• I am beginning to understand but need more practice

• I have no idea what the difference it

Tomorrow we will focus on Kinetic Energy!
