Newton’s first law

Physics; General physics

Newton’s law of universal gravitation

Physics; General physics

The force of gravity, F , between two particles of mass m 1 and m 2 , separated by a distance r , has a magnitude of F = Gm 1 m 2 / r 2 , where G is the gravitational constant. The ...

Newton’s second law

Physics; General physics

F = m a . The net force, F , acting on an object causes the object to accelerate, a . The magnitude of the acceleration is directly proportional to the net force on the object and ...
