Forces and Energy in Motion

Front

What are the two types of forces that impact object movement?

Back

Contact forces (like friction and normal force) and Non-Contact forces (like gravity and magnetism)

Front

What is energy?

Back

Energy is the ability to do work; it powers everything around us.

Front

What are the two types of energy?

Back

Kinetic energy and potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion; the faster something moves, the more kinetic energy it has.

Front

What happens to energy during motion?

Back

Energy is not made or destroyed, just transferred or transformed.

Front

What is potential energy?

Back

Stored energy; for example, a compressed spring has potential energy.

Front

How does height affect potential energy?

Back

The higher an object is from the surface, the more potential energy it has.

Front

What is an example of potential energy?

Back

A car on top of a hill of a roller coaster has more potential energy because of its position.

Front

What occurs during a collision?

Back

When two or more things hit each other with a force, energy is transferred.

Front

What factors affect the amount of energy transferred in a collision?

Back

The speed of the objects and their weight.
