Forces and Motion

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

The box will move in the direction you are pulling, which is typically upward.

Friction makes it harder to move down a hill because it opposes motion.

A pull is a force that moves an object closer to you.

Speed is calculated by dividing distance by time (Speed = Distance/Time).

Friction is a force that opposes the motion of an object.

Motion is the change in position of an object over time.

Gravity is a force that pulls objects toward each other, such as the Earth pulling us down.

Displacement is the shortest distance from the initial to the final position of an object.

Speed is how fast an object moves, while velocity includes direction (speed with direction).
