By nature, laws of Physics are stated facts which have been deduced and derived based on empirical observations. Simply put, the world around us works in a certain way, and physical laws are a way of classifying that “working.”
In other words, the rate of change is directly proportional to the amount of force applied. The Newton's three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion.
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.
Law of Physics has ruels the First Rule: An object will remain at rest or in a uniform state of motion unless that state is changed by an external force.
Second Rule: Force is equal to the change in momentum (mass times velocity) over time.
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.
