Inertia of motion, Newton’s law’s of motion, what is Inertia of motion??

  • It is the inability of a body to change itself its state of uniform motion i.e., a body
    in uniform motion can neither accelerate nor retard by its own.

EXAMPLE-

  1. When a bus or train stops suddenly, a passenger sitting inside tends to fall forward. This is because the lower part of his body comes to rest with the bus or train but the upper part tends to continue its motion due to inertia of motion.
  2. A person jumping out of a moving train may fall forward.
  3. An athlete runs a certain distance before taking a long jump. This is because velocity acquired by running is added to velocity of the athlete at the time of jump. Hence he can jump over a longer distance.
