7.1: Potential and Kinetic Energy

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What type of energy is stored in an object due to its position or height?

Back

Potential energy is the energy stored in an object due to its position or height.

Front

A baseball held by a pitcher has _____________ energy.

Back

Potential energy.

Front

Which passenger has the most potential energy if they are at different heights?

Back

The passenger at the highest point has the most potential energy.

Front

If two objects are moving at the same speed, how do you determine which has more kinetic energy?

Back

The object with the greater mass has more kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy is associated with the position of an object?

Back

Potential energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

Can an object have both potential and kinetic energy at the same time?

Back

Yes, an object can have both types of energy simultaneously, such as a roller coaster at the top of a hill.
