Rest and Motion Definitions Rest :-  An object is said to be at rest if it does not change its position with respect to its surroundings wit h time. ---------- ---------- ---------- ---------- -------- Motion :-  An object is said to be in motion if the position changes with respect to it surrounding and time.

8 types of motions 1)Oscillatory Motion. 2)Rotational Motion. 3)Translational Motion. 4)Periodic Motion. 5)Circular Motion. 6)Linear Motion. 7)Uniform Motion. 8)Non-Uniform Motion

Equations of motion     First Equation of Motion : v = u + a t. Second Equation of Motion : s = u t + 1 /2 a t 2. Third Equation of Motion : v 2 = u 2 + 2 a s.
