What is second law of motion in your own words? Newton Second Law of Motion: According to this law, the rate of change of linear momentum of a body is directly proportional to the external force applied on the body, and this change takes place always in the direction of the force applied. In simple terms, it means that a larger force will change the momentum of an object more quickly as compared to a smaller force. A body at rest persists in its state of rest, and a body in motion remains in constant motion along a straight line unless acted upon by an external force. He developed his three laws in order to explain why the orbits of the planets are ellipses rather than circles, at which he succeeded, but it turned out that he explained much more.

Quantum mechanics is deemed the hardest part of physics. It can also be concluded that the higher the magnitude of force, the higher is the change in momentum of the body. Nevertheless, Newtons laws continue to give an accurate account of nature, except for very small bodies such as electrons or for bodies moving close to the speed of light. Proof: We know, F = m. If no external force acts on a body, then F = 0, since f = ma, a = 0 because mass of a body cannot be 0. But we can increase the time taken to change the momentum in order to reduce the impact of force and avoid injuries or damages.
