See the below image for the Newtons first law diagram. According to Newton’s first law of motion, a body continues to be in a state of rest or in a state of uniform motion along a straight line, unless an external force is applied on the body to change the state.” First law of motion defines inertia.
Newton’s laws first appeared in his masterpiece, Philosophiae Naturalis Principia Mathematica (1687), commonly known as the Principia. In 1543 Nicolaus Copernicus suggested that the Sun, rather than Earth, might be at the centre of the universe.
Newton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
