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 ...

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 ...

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 ...

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 ...

The Force is With You? You may have heard that gravity isn’t a force. This is true. Gravity is not a force; however, this truth leaves us with a number of questions. For example, we’re commonly told ...

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 ...

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 ...

If the universe contains more than three spatial dimensions, as many physicists believe, our current laws of gravity should break down at small distances Nothing seems more certain than the “fact” ...

A force is a push or a pull. For example, when you push open a door you must apply a force to the door. You also must apply a force to pull open a drawer. You cannot see a force but often you can see ...

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 ...
