... other forces. For a stone whirled on a piece of string around in a circle, the centripetal force is provided by the tension within the string. For a vehicle turning a corner, the centripetal force is provided by friction between the tyres and the road. For objects in orbit, for example the Earth orb ...

... no balls are gained. Such a system, which does not gain or lose mass, is said to be a closed system. The second condition is that the forces involved are internal forces; that is, there are no forces acting on the system by objects outside of it.

... Fictitious forces do not exist. So why do we need to give them a moment’s thought? Well, sometimes they make our life easier. Let’s have a couple of examples. 1.1.3.1 Centrifugal Force You may have travelled in one of those fairground rides in which everyone stands against the inside of the curved w ...

... 2.2.1 Statement of the 2nd Law Applying a force on an object produces acceleration. In the figure, we see that increasing the force produces more acceleration, and that increasing the object’s mass causes the acceleration to decrease. Therefore, we conclude Newton’s 2nd law of motion: An object’s ac ...
