Answer:
1.The motion of an body along the straight line is called linear motion. For example, a car running straight towards the destination. The motion in which body moves along the circular path is called circular motion.
2.Rest: If a body does not change its position with respect to its surroundings, the body is said to be at rest. E.g. A table lying in a room is at rest with respect to the walls of the room. Motion: A body is said to be in motion if it changes its position with respect to its surroundings.
