Force and Motion Review

What is velocity?

• A measure of how fast something moves between 2 points
• A measure of both the speed and direction of a moving object
• a force that considers the rate at which acceleration changes
• a force that opposes motion between 2 surfaces that are touching

How do you know an object is in motion?

• It is touching another object
• By its velocity
• Because it  is changing positions
• Gravity is keeping it on the ground
