Define distance in physics.

Back

Distance is the total length of the path traveled by an object, regardless of direction.

Front

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.
