Question

5. What is circular motion? How will you calculate speed of an object in
circular motion?​

Answer 1

Answer:

circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.

In uniform circular motion, angular velocity () is a vector quantity and is equal to the angular displacement (Δ, a vector quantity) divided by the change in time (Δ). Speed is equal to the arc length traveled (S) divided by the change in time (Δ), which is also equal to ||R.
