Define uniform circular motion why is it said to be an accelerated |
Answer» Answer :-The motion of a body along the circumference of the circle is called circular motion. Uniform circular motion :- If a body covers equal distances in equal interval of time, then motion is said to be uniform circular motion. In a uniform circular motion, speed remains constant but DIRECTION of velocity changes. Uniform circular motion is called ACCELERATED because in the circular motion direction of motion continuously changes. Due to CHANGE in direction, velocity also changes CONSTANTLY. As we KNOW that, acceleration is the rate of change of velocity, and in the circular motion velocity continuously changes, circular motion is called accelerated motion. |
