Question

What is Circular Motion?

Answer 1

1. Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path.
2. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation
3. The formula for the centripetal acceloeration in uniform circular motion can be written as :$a_r=\frac{v^2}{R}$,
   where$V$ is the velocity, $a_{{}_r}$ is the centripetal acceleration, $R$ is the radius of the circular path.
4. The centripetal force is acting toward the centre of rotation.
5. The force is given by $$\begin{gathered} F=Ma \\ =\frac{M{V}^2}{R}whereMismassofbody \end{gathered}$$
6. The velocity's direction is tangential to the motion.
