... First, note that the force is spherically symmetric, so that for any point r with magnitude r the potential must be the same. Set r0 = ∞. Since gravity is a central force, we know that it permits a potential because this integral is path-independent. Therefore, we can choose to integrate along the ...

... Friction – a force that opposes the movement of something. A force of friction acts when an object moves through the air or water and/or when solid surfaces slide, or tend to slide, across each other. The direction of this force of friction is always opposite to the direction in which the object or ...
