As we know that force is necessary to produce motion in a body. If any object falls from some height towards the earth, therefore a force must be acting on it. This force is due to the attraction ...

At the end of the 18th century, the British scientist Henry Cavendish measured the force of gravity between two objects for the first time in a laboratory. The objects in question were lead balls, one ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept ...

A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the quirky quantum behavior of tiny atoms. The new results could help set ...

Answers to some of the biggest questions in physics are hanging by a thread in a laboratory at the University of Washington in Seattle. The thread is made of tungsten and measures a bit over 30 inches ...

A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces. A force ...

Rich Schuler, an adjunct instructor and outreach coordinator in the physics and astronomy department at the University of Missouri-St. Louis, provides the following explanation. Gravity can be thought ...

Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...
