Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is Potential Energy?

Back

Potential Energy is stored energy that has the potential to do work. It is often associated with the position of an object in a gravitational field.

Front

At which point in a pendulum's swing is Kinetic Energy highest?

Back

At the lowest point of the swing.

Front

At which point in a pendulum's swing is Potential Energy highest?

Back

At the highest points 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 relationship between Kinetic Energy and speed?

Back

Kinetic Energy increases with the square of the speed; if speed doubles, Kinetic Energy increases by a factor of four.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy is the Joule (J).

Front

How does mass affect Potential Energy?

Back

Potential Energy increases with mass; the more massive an object, the more Potential Energy it has at a given height.

Front

What is the formula for calculating Potential Energy?

Back

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

Front

What happens to Kinetic Energy as an object slows down?

Back

As an object slows down, its Kinetic Energy decreases.
