# What is the equation for uniform circular motion?

## What is the equation for uniform circular motion?

Uniform circular motion has 2 primary formulas. The first is for centripetal acceleration, which says that a=v^2/r. The second is for centripetal force, which says that Fc=mv^2/r.

## What is the formula for calculating the centripetal force?

For a mass M with tangential speed v at radius R, the centripetal force is Fc = Mv2/R. With a period of T, the linear speed is v = 2πR/T and the centripetal force is Fc = 4π2MR/T2. You will change Fc, mass, and radius to measure the effect on the period of rotation.

## When a curved road is banked which force or component of a force acts as the centripetal force?

When the curve is banked, the centripetal force can be supplied by the horizontal component of the normal force. In fact, for every banked curve, there is one speed at which the entire centripetal force is supplied by the horizontal component of the normal force, and no friction is required.

## How do you find the radius of a uniform circular motion?

Step 1: Identify the centripetal acceleration, and the angular velocity . Step 2: Substitute the values identified in step 1 into the formula a c = r ω 2 . Step 3: Solve for the radius of the orbit, , by dividing both sides of the equation by .

## What is uniform circular motion class 9 with example?

Motion of artificial satellites around the earth is an example of uniform circular motion. The gravitational force from the earth makes the satellites stay in the circular orbit around the earth. The motion of electrons around its nucleus. The motion of blades of the windmills.

## What is uniform motion Class 7 short answer?

Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line, and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.

## What are the three formulas of centripetal force?

• where vt is the tangential velocity and r is the radius of the circle.
• If we put acentripetal into Newton’s second law, we get the centripetal force formula:
• acentripetal = ω2 r.
• Fcentripetal = macentripetal = mω2 r.

## What is called centripetal force?

A centripetal force is a net force that acts on an object to keep it moving along a circular path. In our article on centripetal acceleration, we learned that any object traveling along a circular path of radius ‍ with velocity ‍ experiences an acceleration directed toward the center of its path, a = v 2 r ‍ .

## What is the centripetal force on an object in circular motion?

Any net force causing uniform circular motion is called a centripetal force. The direction of a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. According to Newton’s second law of motion, net force is mass times acceleration: net F = ma.

## Is friction opposite to velocity?

The kinetic frictional force is always in the direction opposite to the velocity of the object.

## Is centripetal force real?

Centripetal force is a real force that counteracts the centrifugal force and prevents the object from flying out, keeping it moving instead with a uniform speed along a circular path.

## Is centrifugal force real?

centrifugal force, a fictitious force, peculiar to a particle moving on a circular path, that has the same magnitude and dimensions as the force that keeps the particle on its circular path (the centripetal force) but points in the opposite direction.

## What is the formula for centripetal and centrifugal force?

Centrifugal Force Centripetal force
Formula, : F = ma = mv²/r Formula, : F = ma = mv²/r
The direction is along the radius of the circle, from the center towards the object. The direction is along the radius of the circle, forming the object towards the center.

## What is the formula and problem of centripetal force?

Calculation of Centripetal Force The product of mass (kg) and tangential velocity (m/sec) squared, divided by the radius (m), is the formula of centripetal force. Where, F represents the centripetal force, m = mass of the object, v = speed or velocity of the object and r = radius.
