If one body is at rest and we try to move it, then it will resist.
Correct answer: A. Inertia of motion
- A. Inertia of motion
- B. Inertia of rest
- C. Inertia of turning
- D. Inertia of acceleration
Explanation
An object stays where it is placed, and it will stay there until you or something else moves it. (i.e., Dust particles stay at rest until you shake a carpet). The inertia of motion: An object will continue at the same speed until a force acts on it. (i.e., the body going forward when a car stops). Inertia of motion and inertia of rest both obeys Newton's first of motion. In inertia of motion, the body must be in motion and must be in uniform motion whereas in inertia of rest, the body must be in state of rest.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
