Motion
Essential Understandings:
Pushes and pulls change the direction and speed of moving objects
Applying less force makes an object move less
Applying more force makes an object move more
Friction is a force that affects motion
Objects with more mass require more force to change their motion/direction
Two factors that determine motion are force applied and the distance an object moves
Increasing or decreasing the force applied to an object affects the size of the change
