The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

Learn how to calculate the universal gravitational force between two objects! This video explains Newton’s Law of Gravitation, walking you through the formula, units, and a step-by-step example to ...

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 ...

Physicist Markus Aspelmeyer vividly remembers the day, nearly a decade ago, that a visitor to his lab declared the gravitational pull of his office chair too weak to measure. Measurable or not, this ...

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. Observations of ...

The supertankers TI Europe and TI Oceania are two of the largest free-moving objects made by man, how does gravitation affect them? Each ship has a total mass of \(5\times {10^8}kg\) and they could ...

Take a pencil, stretch out your arm, and let go. We all know that the pencil will fall. OK, but what about dropping a bowling ball? Is that the same thing? No wait! How about a watermelon dropped off ...

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 ...
