Question

115). Define uniform circular motion. Is it an accelerated motion? If yes, what is the direction of acceleration? Give an
example of this type of motion?
​

Answer 1

$\huge\text{\underline{\boxed{Answer\rightarrow}}}$

Definition $\rightarrow$ The movement of the body with a constant speed in a circular path is know as Uniform circular motion.

Yes, the Uniform circular motion is an accelerated motion.

There is an acceleration called centripetal acceleration or radial acceleration which acts along the radius and towards the center which keeps the body along its circular path.

When a body moves in uniform circular motion, its speed remains constant, but, the direction of tangential velocity changes each time. Due to the change in direction, an acceleration will be produced called tangential acceleration.

$\huge\text{Note}\rightarrow$ But tangential acceleration in uniform circular motion is zero.

$\sf{Examples}\rightarrow$

• Motion of artificial satellites around the earth is an example of uniform circular motion. The gravitational force from the earth makes the satellites stay in the circular orbit around the earth.

• The motion of electrons around its nucleus.

• The motion of blades of the windmills.

• The tip of second’s hand of a watch with circular dial shows uniform circular motion.
