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 the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object has due to its height above the ground, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

At which point in a pendulum's swing is the potential energy highest?

Back

The potential energy is highest at the highest points of the swing, where the pendulum is momentarily at rest.

Front

At which point in a pendulum's swing is the kinetic energy highest?

Back

The kinetic energy is highest at the lowest point of the swing, where the pendulum is moving fastest.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, conserving the total mechanical energy.

Front

What is the relationship between mass and potential energy?

Back

Gravitational potential energy is directly proportional to the mass of the object; more mass means more potential energy at the same height.

Front

What is the relationship between height and potential energy?

Back

Gravitational potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy due to its deformation.

Front

How do you calculate the kinetic energy of an object?

Back

Kinetic energy is calculated using the formula KE = 1/2 mv², where m is the mass of the object and v is its velocity.
