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

5

Multiple Choice

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

1

a bag of marbles on a table

2

a picture hanging on a wall

3

a ball rolling down a hill

4

standing at the top of the stairs

6

media

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

7

media

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

8

media

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

media
  • 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

1

a book on a bookshelf

2

burning gasoline to power a car

3

wind causing tree branches to sway

4

boing water over a fire

11

Multiple Choice

Question image

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?

1

the coaster loses energy

2

the energy is stored in the wheels for later use

3

the energy changes form to kinetic energy

4

the roller coaster gains energy

15

media

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!

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
