This means that two 1 kilogram masses a distance of 1 meter apart would have a gravitational force of a super tiny value. Gravity is very weak. But how do you find the value of G?

The tension in the cable is adjusted so that the net downward force (the cable pulling up and gravity pulling down) is the same as the downward-pulling gravitational force on the moon.

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 ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on ...

The crowning achievement of the 18th-century researcher was the design of the first experiment to measure the force of gravity between masses in a lab ...

You and your kids can become the Sun as you experiment with the ways gravity, inertia, and centripetal force keep the solar system in motion.
