Uniform motion along a circular path means the object moves at a constant speed. However, velocity is a vector quantity, defined by both magnitude (speed) and direction. In circular motion, the direction of motion is constantly changing as the object moves along the curve. Since the direction of motion is changing, the velocity of the car is also continuously changing, even though its speed is constant.<\/section>\n
Speed is the magnitude of velocity. In uniform circular motion, speed is constant. Velocity is a vector (speed + direction). The direction of motion is always tangent to the circular path and continuously changes. Therefore, velocity changes. Momentum is mass times velocity (p = mv). Since velocity changes, momentum also changes.<\/section>\n
Since the velocity is changing, there is acceleration. This acceleration is called centripetal acceleration, and it is directed towards the center of the circle. It is responsible for changing the direction of the velocity vector. Uniform circular motion is an example of accelerated motion even though the speed is constant.<\/section>\n","protected":false},"excerpt":{"rendered":"
