Weight is the force acting on an object due to gravity - it has the unit newtons (N) and acts towards the centre of a gravitational field. So weight is a gravitational force on an object that has mass ...

A pair of mathematicians have proposed a unified theory of dark matter and dark energy that alters Einstein's equations describing the fundamentals of gravity. They suggest the law of energy and ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...
