Newton's 2nd gives the measurement of:
Correct answer: C. Force
- A. Acceleration
- B. Momentum
- C. Force
- D. Inertia
Explanation
Newton's second law of motion is primarily concerned with how the net force acting on an object results in acceleration. It is expressed mathematically as F = ma, where F stands for force, m for mass, and a for acceleration. Thus, it gives a way to calculate the force. While acceleration plays a role in the equation, the law itself is about the relationship between force, mass, and acceleration. The other options-momentum and inertia-are related to motion but are not directly measured by Newton's second law.

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.
