Question: What is difference between rest and motion?

Answer: A body is said to be at rest if doesn't change it's position with respect to its surroundings while a body is said to be in motion if it continuously changes it's position with respect to its surroundings.

Question: How rest and motion are relative?

Answer: The state of rest and motion of a body is always relative. For example a person is travelling in a bus. He is in state of rest with respect to a person sitting inside the bus but to an observer outside the bus, he is in state of motion.

Question: What is translatory motion?

Answer: The motion of a body along a straight line without any rotation is said to be translatory motion. The motion can be straight lined or along a curved path as well.

Question: What is difference between linear and translatory motion?

Answer: A body moving in a curved path without rotation is said to be in translatory motion while an object moving along a straight line only is said to be in a linear motion

Question: What is difference between circular and rotatory motion?

Answer: A body moving along a circular path is said to be in circular motion while if a body spins around it's axis then it is said to be in rotatory motion. For example a stone attached to string is whirled in a circle is circular motion while rotation of stone around it's own axis is rotatory motion.
