- Motion is a change of position; it can be described in terms of the distance moved or the displacement.
- The motion of an object could be uniform or non- uniform depending on whether its velocity is constant or changing.
- The speed of an object is the distance covered per unit time, and velocity is the displacement per unit time.
- The accelaration of an object is the change in velocity per unit time.
- Uniform an non-uniform motions of objects can be shown through graphs.
- If an object moves in a circular path with uniform speed, its motion is called uniform circular motion.
