What is a force?

Push or Pull 

100

Two forces equal in strength and opposite in direction

Balanced forces

Describe the difference between speed and velocity 

Speed = how fast an object moves & Velocity = speed with direction

How can you model forces?

Arrows to show strength and direction

What is a Normal Force?

A force applied perpendicularly to a surface.
