## What is the force of centripetal force?

Table of Contents

Centripetal force is the name given to any force which causes a change in direction of velocity toward the center of the circular motion. The component of the force which is perpendicular to the velocity is the part resulting in the centripetal force.

## What is circular motion formula?

Therefore for an object to move along a circular path, there must be an acceleration that will always be perpendicular to the velocity. The circular motion may be uniform as well as non â€“uniform….a_{rad} = \frac{4{\pi}^2 R}{T^2}

a_{rad} | Radial acceleration |
---|---|

T | Time Period |

V | Velocity |

C | Circumference |

**What is centripetal force class 9th?**

Centripetal force is the force that acts on the body to keep it moving in a curved path. Centripetal force is an actual force that is directed inward towards the centre of rotation. In simple words, while twirling an object tied to a string, the string will exert an inward centripetal force on the object.

**What is centripetal force class 10th?**

A force that acts on a body moving in a circular path and directed towards the centre around which the body is moving is called Centripetal force. When an object travels around a circular path with a constant speed, it experiences an accelerating centripetal force towards the centre.

### How is a v2 R?

A body that moves in a circular motion (of radius r) at constant speed (v) is always being accelerated. The acceleration is at right angles to the direction of motion (towards the center of the circle) and of magnitude v^2 / r. The direction of acceleration is deduced by symmetry arguments.

**What is the equation for centripetal?**

This means you can find the centripetal force without the tangential velocity by using the ordinary equation for gravitational force: F = Gm 1 m 2 / r 2 Where m 1 and m 2 are the masses, G is the gravitational constant, and r is the separation between the two masses.

**How to calculate centripetal speed?**

r = v 2 / a. v = (ar) 1/2. Where: a = Centripetal acceleration and is directed perpendicular to v (m/s 2, in/s 2) v = Tangential velocity or instantaneous velocity (m/s, ft/s) r = Radius of the circle (m, ft) m = meters. ft = feet. s = seconds.
