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 ...

Watch this video to find out more about forces that can act on objects without touching them. Gravitational forces that make things fall down to the ground – unless another force stops them. An apple ...

It's perhaps the second week of your introductory physics course. Your instructor starts talking about friction and writes the following two formulas on the board. Then there is probably some sort of ...

The long-range influence of gravity, despite its comparative weakness, stems from its inverse-square law, where its flux remains constant over arbitrary distances due to the compensatory increase in ...

Most of us take gravity as an assumed part of our living realities, but why? Most of us take gravity as an assumed part of our living realities, but why? Basic physics introduces us to the concept 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 ...

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 ...
