What does a negative velocity indicate?

Back

A negative velocity indicates that the object is moving in the opposite direction to the defined positive direction.

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
