1st law of motion gives the definition of:
Correct answer: D. Force
- A. Rest
- B. Motion
- C. Velocity
- D. Force
Explanation
The first law of motion, also known as Newton's first law, defines Force.Newton's first law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. This law introduces the concept of inertia and defines force as the cause that changes the state of rest or motion of an object.

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.
