What is motion

Objects which are moving around us are said to be in motion whereas the objects which are not moving are said to be at rest.

Motion is classified into various types based on the path they follow.

• Rectilinear Motion – This is a motion where objects move along a straight line. Examples march past of soldiers, sprinters in race, falling stones etc.
• Circular Motion - This is a motion where objects move along a circular path. Examples hands of a clock, blades of a fan, rotation of earth around the sun etc.A type of circular motion where an object spins on its own axis, it is called rotational motion. Example rolling ball, spinning top etc.
• Periodic Motion – This is a type of motion where the object repeats its motion after a fixed interval of time. Examples pendulum of a clock, motion of child on a swing etc.
