Front

What is a contact force?

Back

A contact force is a force that occurs when objects are physically touching each other.

Front

How can you describe a force?

Back

A force can be described as a push or pull.

Front

What factor has the most impact on kinetic energy?

Back

Velocity (speed) has the most impact on kinetic energy.

Front

Where is the most potential energy in a roller coaster system?

Back

The most potential energy is at the highest point of the roller coaster.

Front

What is the relationship between potential energy and kinetic energy in a system?

Back

The amount of potential energy put into a system is equal to the amount of kinetic energy that will be in the system.

Front

What are the two main types of forces?

Back

The two main types of forces are contact forces and non-contact forces.

Front

What is an example of a contact force?

Back

An example of a contact force is friction.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

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

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; more mass means more energy when moving.
