Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

The energy an object has due to its motion.

Front

What is Potential Energy?

Back

The energy an object has due to its position or condition.

Front

When does an object have NO kinetic energy?

Back

When it's at rest.

Front

At which point is kinetic energy highest in a swinging pendulum?

Back

At the lowest point of the swing.

Front

At which point is potential energy greatest in a swinging pendulum?

Back

At the highest point of the swing.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

Potential energy increases as height increases.

Front

How does speed affect Kinetic Energy?

Back

Kinetic energy increases with the square of the speed.

Front

What happens to Kinetic Energy as an object slows down?

Back

Kinetic energy decreases.
