Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies toward each other, such as the Earth and an object.

What is the role of friction in motion?

Back

Friction opposes motion, slowing down or stopping moving objects.
