Define Newton’s second law of motion and give the relation
between kinetic energy and momentum
Answers
Answer:
The SI unit for momentum is kg · m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

Answer:
Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.
The kinetic energy of a body is the ratio of the square of the momentum and the twice of the mass of that body. Momentum of a body is the product of its mass and velocity. The rate of change in momentum is called force.
