8 Motion – Notes
Introduction to Motion
Motion is a state of an object when there is a change in the position of the object with respect to its surroundings.
An object moving along a straight line or in a specified direction is said to have one-dimensional motion or linear motion.
If an object moves in two directions in a given plane at the same time, then it is said to have two dimensional motion.
When an object moves in three directions at the same time, it is said to be in three-dimensional motion.
