You want to conduct an experiment with a simple machine. First, you make an inclined plane by placing a book under one end of a ruler. Next, you will place a marble in the groove of the ruler at the top of the incline. Then, you will release the marble and measure the distance it travels. How could you increase the distance traveled by the marble?
What is increasing the height of the book?

What is the difference between speed and velocity?
What is speed is the measure of motion or how fast/slow you are moving and velocity is speed in a direction?

This position is when the ball has the greatest amount of kinetic energy.
What is position D?
When the ball is at its highest point, it has potential energy. When the ball is falling towards the table, it has kinetic energy. It has the most kinetic energy at the very end of its descent when it is moving the fastest.

Name an example of potential energy.
Potential Energy: Stored energy that could cause change in the future.
Potential Energy Examples
- A raised object, such as a book, weight, or apple.
- A person at the top of a diving board.
- An object at the top of a hill.
- A stretched spring or rubber band.
- A drawn bow.
- Water at the top of a waterfall.
- Water behind a dam.
- A charged battery.
