Forces and Motion

A change in an object's position.

When a moving object speeds up, slows down, or changes direction.

With measures of distance, direction, and time.

A force that pulls objects toward each other, like a force that pulls a car down a hill.

A smaller, more compact object like a crumbled piece of paper will fall more quickly than a flat piece of paper.

A push or pull that can change the motion of an object.

The speed of an object in a specific direction.

A force that opposes motion between two surfaces in contact.

The more mass an object has, the stronger the gravitational pull it exerts.

Forces that are equal in size but opposite in direction, resulting in no change in motion.
