Potential and Kinetic Energy

Potential and Kinetic Energy

Understanding Kinetic and Potential energy.

Multiple Choice

Which type of energy has to do with objects in motion?

• Potential

• Kinetic

Energy

• Potential Energy- Energy due to an objects position or condition.

• Kinetic Energy - Energy due to an objects motion.

• Energy cannot be created or destroyed only change.

How to increase potential energy.

There are 2 ways to increase the potential energy of an object in relation to gravity.

-Increase the object's height.

-Increase the object's mass.

Multiple Choice

Which of these has the most potential energy.

• A

• B

• C

• D

Kinetic Energy

• The amount of Kinetic energy and object has is related to to 2 factors.

• Mass of the object

• Speed of the object

Multiple Select

If a football player wants to become better at tackling by increasing his or her kinetic energy, how can the player do this?

• Increase his/her height

• Increase his/her speed

• Increase his/her mass

• Decrease his/her speed

Potential and Kinetic Energy

Notice that as the kinetic energy increases the potential energy decrease.

When the coaster goes back up the hill the energy is converted back to potential energy.

Open Ended

The Law of Conservation of Energy states, "Energy is never created or destroyed only change." How does the relationship between potential and kinetic energy illustrate this?

Let's look at a pendulum to explore this.
