Energy Transfer and Collision

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What happens during a collision?

Back

During a collision, energy is transferred between colliding objects.

Front

What types of energy are often released during a collision?

Back

Heat and sound energy are often released during a collision.

Front

How does pulling back a wrecking ball affect its energy?

Back

Pulling back a wrecking ball increases its potential energy, which converts to kinetic energy when released.

Front

What is a contact force?

Back

A contact force is a force that occurs when two objects are in physical contact with each other.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object is set in motion.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car or a rolling ball are examples of kinetic energy.

Front

What is an example of potential energy in everyday life?

Back

A drawn bow or a book on a shelf are examples of potential energy.
