Back

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

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is constant speed?

Back

Constant speed means an object covers equal distances in equal intervals of time.
