Hello students, in this question, we have to explain the terms velocity in acceleration in terms of uniform circular motion.
00:10
First of all, what is a circular motion? a circular motion is defined as the movement of an object along a circumference of the circle or rotation along a circular path.
00:21
We have two type of circular motion.
00:25
One is the uniform circular motion and another one is the non -uniturricular motion.
00:30
Circular motion.
00:32
In uniform circular motion, the object moves along a circular path with a constant speed.
00:41
That means the speed is constant, whereas in non -uniform circular motion, the object moves along a circular path with variable speed.
00:55
Now, we have been asked for the uniform circular motion.
01:00
Let us suppose this particle is moving along a circle and we have marked the positions a and b of the particle.
01:08
Now, in uniform circular motion, one very important thing is the tangential acceleration is equal to 0, whereas the only acceleration which is present is the centripetal acceleration.
01:21
Since the tangential acceleration is 0, so the velocity in magnitude remains constant, but it constantly changes its direction...
