Why is a particle in uniform circular motion not moving at a constant velocity?

Why is a particle in uniform circular motion not moving at a constant velocity?



Any explanation?Why is a particle in uniform circular motion not moving at a constant velocity?It is moving at a constant speed.



velocity is a vector, and has both magnitude (the speed) and direction. Since the direction is constantly changing, the vector velocity is constantly changing also.



.Why is a particle in uniform circular motion not moving at a constant velocity?It is not moving in a straight line. Read Newton's 1st Law again. Remember velocity is a vector, it has magnatude and direction. Chamge either and you change the vector and that requires an acceleration.Why is a particle in uniform circular motion not moving at a constant velocity?Because there is always acceleration in a circular motion.
