Uniform Circular motion is an accelerated motion. In this quick post we will first discuss what uniform circular motion is and then will find how this motion is with acceleration in spite of being uniform.

Uniform Circular Motion is a motion with acceleration – Explain how?

An object that moves in a circle at constant speed is said to experience uniform circular motion. The magnitude of the velocity remains constant in this case, but the direction of the velocity continuously changes as the object moves around the circle.

Now we all know that acceleration is defined as the rate of change of velocity. Velocity is a vector quantity. Hence, even a change in direction of velocity is an acceleration, just as a change in its magnitude is.

On the other hand, Speed is a scalar quantity, so just change in direction doesn’t stop it being uniform.

Thus, an object revolving in a circle is continuously accelerating, even when the speed remains constant. Hence, it is said that Uniform Circular motion is a motion with aceleration.
