How do you find average force in circular motion?

This net force is often called the centripetal force. Since the acceleration of an object undergoing uniform circular motion is v2/R, the net force needed to hold a mass in a circular path is F = m (v2/R).

What is the value of centripetal force of on an object of mass m moving with velocity v in a circular track of radius r?

v2r
The centripetal force on a body of mass ‘m’ and velocity ‘v’ moving in circular orbit of radius ‘r’ is given by F = mv2r.

How much work is done on the body if a body of mass m is moving in a circular path of radius r?

So, the work done by the object in circular path is zero.

What are the force acting on mass in vertical circular motion?

Centripetal force is the force which makes the body rotate in a circular path. And from Newton’s 3rd law of motion centrifugal force is the equal and opposing force to the body. Every object which is moving against gravity has a mg force acting downward towards the ground.

What is the average force?

The average force is the force exerted by some object moving at some defined rate of speed i.e. velocity for a defined period of time. Therefore, the average force is equal to the mass of the body multiplied by the average velocity of the object over the defined time.

How do you find the average force acting on an object?

Formula for Average Force The mass of the object multiplied by the average velocity over the definite time is equal to the average force.

What is the value of k in centripetal force?

F=mv3×r (where k=1)

What do you understand by centripetal force a particle of mass?

A centripetal force (from Latin centrum, “center” and petere, “to seek”) is a force that makes a body follow a curved path. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path.

How much work must be done by a force on 50kg body in order to accelerate it from rest to 20m s in 10s?

4×104 J.

How much work is done when a body moves along arc of a circular path explain your answer?

When a body moves in a circular path, no work is said to be done by the body as the force is directed towards the centre of circular path (the body is acted upon by the centripetal force). At all points the displacement is along the tangent to the circular path, (i.e normal to the direction of the force).

When a particle is moving in a vertical circle?

Its radial acceleration is varying but tangential acceleration is constant.

What is the magnitude of average force during a half revolution?

From the given information, the time period for a complete rotation is 2 π r v. Since the momentum changes to the opposite direction during half revolution, the magnitude of change is 2 m v. So the magnitude of average force is 2 m v 2 π r. How this 19-year-old earns an extra $3600 per week.

What is the average force on a circle of radius?

The force, F, acting on a mass, m, moving at speed, v, in a circle of radius, r, is given by: I assume that v and r are constant as no information is stated to the contrary. Hence F will be constant. So the average force will be m v v / r .

Why is centripetal acceleration constant in uniform circular motion?

Because an object in uniform circular motion undergoes constant acceleration (by changing direction), we know from Newton’s second law of motion that there must be a constant net external force acting on the object. Any force or combination of forces can cause a centripetal acceleration.

How do you find the centripetal force of a particle?

Since the particle moves with constant speed, the net force acting on it is the centripetal force whose magnitude is m V 2 R, and whose direction at any time t is − r ^, so the centripetal force F → = − m V 2 R ( cos ⁡ ω t i ^ + sin ⁡ ω t j ^).
