Question

8. Explain how Newton's second law of motion can be used to define force.
​

Answer 1

Answer:

The second law states that the rate of change of momentum of an object is directly proportional to the force applied, or, for an object with constant mass, that the net force on an object is equal to the mass of that object multiplied by the acceleration.

Answer 2

Answer:

According to Newton's second law, the rate of change of momentum is directly proportional to the applied force, so. where k is a constant. The unit of force is so chosen that k is equal to one. If m = 1, a = 1 and F = 1, then. So a unit force is that force which produces a unit acceleration in a body of unit mass.
