Extra Credit Kinetic and Potential Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a cliff has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does potential energy change as an object falls?

Back

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

Front

At what point does an object have maximum kinetic energy during a fall?

Back

An object has maximum kinetic energy just before it hits the ground.

Front

What happens to kinetic energy when a car accelerates?

Back

When a car accelerates, its kinetic energy increases.

Front

What is the relationship between potential energy and height?

Back

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

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

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

Front

What happens to potential energy at the highest point of a swing?

Back

At the highest point of a swing, potential energy is at its maximum and kinetic energy is at its minimum.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a stretched rubber band, which has energy stored due to its position.
