Question

what is uniform circular motion? derive an expression for centripetal acceleration​

Answer 1

◆━━━━━━━▣✦▣━━━━━━━━◆

✰Uniform circular motion:

When an object moves on a circular path with constant or uniform speed, it is said to have uniform circular motion. For example: motion of hands of a clock.

✌Derive an expression for centripetal acceleration

rate of change of tangential velocity is called as the centripetal acceleration.

❥$f = \frac{m {v}^{2} }{r}$

centripetal acceleration is given by,

❥$ac = \frac{f}{m}$

❥$\frac{m {v}^{2} }{r} upon \: m$

❥$ac = \frac{ {v}^{2} }{r}$
