Potential and Kinetic Energy Roller Coaster

Potential and Kinetic Energy

Open Ended

Scholars, take a moment and carefully study this image. PAY ATTENTION to where potential energy and kinetic energy are labeled along the roller coaster ride. Now predict what you think is potential energy and kinetic energy. WRITE A DEFINITION FOR EACH TYPE OF ENERGY.

Scholars, take a moment to study and compare these 2 pictures. What observations can you make about where the people in these images get their energy from?

Energy

How is energy defined in science?

* The ABILITY to move matter or CHANGE matter in some way

 * The ability to do WORK

The two types of energy that will be discussed in this lesson are:

* POTENTIAL ENERGY

* KINETIC ENERGY

Multiple Choice

The ability to do work is __________.

• work

• force

• energy

• gravity

Potential Energy

STORED energy or energy READY TO BE RELEASED

Kinetic Energy

Energy RELEASED or energy IN MOTION

How does Potential Energy (PE) work?

When something has PE, it has the ability to possibly move based on its POSITION or SIZE.

Multiple Choice

Stored energy or energy ready to be released is __________.

• kinetic

• potential

• force

• speed

Multiple Choice

Energy in motion is __________.

• kinetic

• potential

• force

• speed

Scholars, let's say both balls will fall into the bowl of water.

What is going to happen?

Open Ended

You will notice that the smaller ball makes a little splash as it falls into the bowl. The heavy ball makes a bigger splash. Why?

Potential and Gravitational Energy

• Both balls had potential energy as they rested on the table.

• By resting up on a high table, they also had gravitational energy.

• By moving and falling off the table (movement), potential and gravitational energy changed to kinetic energy. Can you guess which of the balls had more kinetic energy?

Kinetic Energy and Light and Heavy Objects

• HEAVIER objects or objects with MORE MASS that are moving have MORE kinetic energy than lighter ones. Therefore, the green ball will have more kinetic energy than the red ball.

• For example, a bowling ball traveling 10 m/s (a very fast sprint) carries a lot more kinetic energy than a golf ball traveling at the same speed.

Multiple Choice

Which has greater kinetic energy?

• car

• person

• same

• none
