A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down with quantum physics.

Higher Gravitation Gravity and mass Projectile motion is analysed in terms of vertical and horizontal components. The gravitational force between objects depends on their mass and the distance ...

In this expression, the gravitational force depends on both the masses of the two interacting objects as well as the distance between them (the r) in the expression.

This larger gravitational force between two bodies relies on something called the gravitational constant that is used to calculate the relative gravitational force between two objects.

Measuring devices have become sensitive enough to detect the gravitational forces between tiny objects and may soon cross the quantum threshold.

However, in the limit of low velocities and weak gravitational fields, Einstein’s theory still predicts that the gravitational force between two point objects obeys an inverse-square law.

Ever since the work of Isaac Newton in 1687, physicists have understood gravity to be universal: every object exerts a gravitational force proportional to its mass on everything around it.

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured.

Although gravity seems strong in our everyday lives, such as when lifting a heavy object, it is the weakest of the four fundamental forces. The gravitational force between two bodies is ...
