Potential and Kinetic 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 hill 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

Where is kinetic energy maximum on a roller coaster?

Back

At the bottom of a big hill.

Front

What type of energy is stored when you compress a spring?

Back

Elastic energy.

Front

What happens to kinetic energy as an object's speed increases?

Back

The kinetic energy increases.

Front

What type of energy does a baseball have when held by a pitcher?

Back

Potential energy.

Front

What is the formula for kinetic energy?

Back

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

Front

What is gravitational potential energy?

Back

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

Front

Can potential energy be converted to kinetic energy?

Back

Yes, potential energy can be converted to kinetic energy, such as when a roller coaster descends from a height.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a running dog, or a flowing river.
