Uniform Circular Motion
Uniform circular motion could be elaborates as the motion of an object within a circle at a constant speed. As an object moves within a circle, it is continually changing its direction. At all examples, the object is moving tangent to the circle. Because the direction of the velocity vector is the similar as the direction of the object's motion and the velocity vector is directed tangent to the circle as well. An animation at the right depicts this through means of a vector arrow.
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
