Q: Newton second law of motion:
  • A. Explains the relationship between forces on two mutually effective objects.Explains the relationship between forces on two mutually effective objects.
  • B. Also known by the law of inertia.
  • C. It is helpful to understand the effects of force.
  • D. Also known by the law of conservation of energy.
Correct Answer: Option C - The rate of change of momentum of an object is proportional to the force exerted on that object. The momentum changes in the direction of the force. In the second law, the force on an object is equal to product of its mass and its acceleration. F = ma where, m = mass and a = acceleration. Hence Newton second law of motion is helpful to under stand the effects of force.
