Definition(formulas if needed):

Example:

Energy Transformation

• Potential Energy is the highest at the top

• Halfway down they are equal

• Kinetic Energy is highest at the bottom

• PE + KE = Total Energy (Sometimes called mechanical energy or total mechanical energy)

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 Choice

• mechanical is more dangerous

• EMS is more relevant

• EMS requires a medium to travel

• EMS doesn't require a medium to travel

Multiple Choice

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.
