What is Motion?
Motion is the process of changing of position by an object. Everything around us is in motion even seemingly stationary things like buildings , road is moving along with rotation of earth , every planet orbits the sun which orbits center of galaxy and galaxy itself is in motion. The study and comparison of “Motion” is called “Kinematics” in physics.
General properties of Motion:
a> The motion is always in a straight line. The line may be in any direction like horizontal , vertical etc. but it must be a straight line.
b> Motion is caused in an object due to the force (Push and Pull) applied on the object.
c> An object is considered to be in motion only if it moves like a single particle or every parts of the object is move in same direction and with same speed.
