The quantitative value of force is given by:
Correct answer: A. Newton's second law of motion
- A. Newton's second law of motion
- B. Newton's third law of motion
- C. Newton's first law of motion
- D. None of these
Explanation
Newton's second law of motion gives the quantitative value of force i.e. it measures force.It states that when a force is applied on a body, it accelerates in the direction of the force with the acceleration being directly proportional to the force and inversely proportional to the mass of the body.Mathematically, this can be written as:F = ma

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.
