Newton first law of motion is also known as:
Correct answer: A. Law of inertia
- A. Law of inertia
- B. Law of electromagnetism
- C. Law of universal gravity
- D. Law of conservation of momentum
Explanation
The property of a body to remain at rest or to remain in motion with constant velocity is called inertia. Newton's first law is often called the law of inertia.

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.
