... When an object is in motion on a surface or through a viscous medium, there will be a resistance to the motion. This is due to the interactions between the object and its environment. This resistance is called the force of friction. ...

... Proof of: a = v2 / r NOTE: This is not required for A2 AQA Physics Consider an object moving at constant speed, v from point A to point B along a circular path of radius r. Over a short time period, δt it covers arc length, δs and sweeps out angle, δθ. As v = δs / δt then δs = v δt. The velocity of ...
