Newton's law of gravitation. (nt'nz) The principle that expresses the force of gravitational attraction between two bodies as a function of their mass and their distance.
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass. newton's second law motion acceleration force. Law of force and acceleration this is also known as Newton's second law of motion. There's 3 components to Newton's second law. The first one is that a force on an object will cause that other to accelerate, the second is this acceleration is directly proportional to the force so the harder I push, the harder it accelerates okay.
