## How do you find the coefficient of friction using centripetal force?

Now we have a relationship between centripetal force and the coefficient of friction. Using the equation Fc=mv2r.

### What happens to centripetal force if the mass doubles?

What happens to the centripetal acceleration on the object when the mass is doubled? Possible Answers: The centripetal acceleration remains the same. The centripetal acceleration remains the same.

#### How do you find velocity using centripetal force?

Velocity (v) is tangential (lies on a tangent to the path). Centripetal acceleration and centripetal force are centripetal (point toward the center of a circle) or radial (lie on the radius of a circle)….ω =

ac = | centripetal acceleration [m/s2] |
---|---|

T = | period of revolution [s] |

**Is tension a centripetal force?**

A centripetal force is a net force that acts on an object to keep it moving along a circular path. The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal forces.

**Is centripetal force equal to normal force?**

Only the normal force has a horizontal component, and so this must equal the centripetal force—that is, Nsinθ=mv2r θ = m v 2 r .

## What is the centripetal force equal to?

The magnitude F of the centripetal force is equal to the mass m of the body times its velocity squared v 2 divided by the radius r of its path: F=mv2/r. According to Newton’s third law of motion, for every action there is an equal and opposite reaction.

### What happens to the centripetal force as the mass increases?

As the mass of an object in uniform circular motion increases, what happens to the centripetal force required to keep it moving at the same speed? It increases, because the centripetal force is inversely proportional to the mass of the rotating body.

#### Is centripetal force directly proportional to mass?

2). That relation tells us that the centripetal force is proportional to the mass and to the radius and proportional to the square of the frequency.

**What is centripetal force equal to?**

**Is centripetal force real?**

With this definition, centripetal force would be real and centrifugal not real. Centripetal force is the force needed to make something move in a circle. A constant magnitude centripetal force that is always perpendicular to the direction of motion will make the object move in a circle.
