## What is the centripetal acceleration of a particle of mass m is moving in a circle of radius r?

Centripetal acceleration of a particle of mass m moving in a circle of radius r is 4/r2.

## When a particle of mass moves in a circular path?

A particle of mass m is moving in a circular path of constant radius r such that its centripetal acceleration a is varying with time t as a = k2rt2 where k is a constant.

## What is the force on the body of mass m is moving in a circle of radius r with constant speed v?

A rigid body of mass m is moving in a circle of radius r with a constant speed v. The force on the body is mv2r and is directed towards the centre.

## What causes a car to move in a circle?

As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion.

## What is the formula for centripetal acceleration with mass and radius?

By substituting the expressions for centripetal acceleration a c a c ( a c = v 2 r ; a c = r ω 2 ) , ( a c = v 2 r ; a c = r ω 2 ) , we get two expressions for the centripetal force F c F c in terms of mass, velocity, angular velocity, and radius of curvature: F c = m v 2 r ; F c = m r ω 2 .

## What is the formula for the centripetal acceleration of a circle?

The centripetal acceleration ac has a magnitude equal to the square of the body’s speed v along the curve divided by the distance r from the centre of the circle to the moving body; that is, ac = v2/r. Centripetal acceleration has units of metre per second squared.

## What is the equation of a particle moving in a circular path?

The equation of motion of a particle moving on circular path (radius 200 m) is given by s = 18 t + 3t2 – 2t3 where s is the total distance covered from straight point in metres at the end of t seconds.

## What happens when a particle moves in a circular path?

if you take any reference point on the circle on which it is moving and observe the particle you will find it comes back to the same reference point with the same velocity after equal gaps of time. This is what we mean when we say that the motion repeats” itself.
