Centripetal force is defined as any net force causing uniform circular motion. The centripetal force is not a new kind of force. The label “centripetal” refers to any force that keeps something turning in a circle. That force could be tension, gravity, friction, electrical attraction, the normal force, or any other force.
This equation shows that the net force required for an object to move in a circle is directly proportional to the square of the speed of the object. For a constant mass and radius, the F net is proportional to the speed 2. The factor by which the net force is altered is the square of the factor by which the speed is altered. Subsequently, if the speed of the object is doubled, the net force required for that object's circular motion is quadrupled.
Since the acceleration of an object undergoing uniform circular motion is v 2 /R, the net force needed to hold a mass in a circular path is F = m (v 2 /R). In this lab you will investigate how changes in m, v, and R affect the net force F needed to keep the mass in a circular path. I 2015-07-23 If the circular motion is vertical then the value of the velocity is not constant. In each point of the orbit the centripital force is the sum of forces in the y-direction. This y-net-force is changing the direction of velocity while the x-net-force is changing speed. According to Kinematics.

The distance an object moves in a circular motion is the circumference of the circular motion, which is equal to 2*pi*R. Using the definition of circumference (c=π*2*r) and the definition of velocity (v=d/t), we can derive this formula: v=2*π*R/t.

A warning about the term "centripetal force" In circular motion many people use the term centripetal force, and say that the centripetal force is given by: I personally think that "centripetal force" is misleading, and I will use the phrase centripetal acceleration rather than centripetal force whenever possible. The force of friction is what keeps the car in circular motion, preventing it from flying off the track. In other words, the frictional force will be equal to the centripetal force. We can cancel mass from either side of the equation and rearrange to solve for the coefficient of friction: Force and Acceleration in Circular Motion Introduction Acceleration is the time rate of change of velocity.
As the velocity of a rocket in a circular orbit near a black hole increases, the outwardly The resulting equation relates the real experienced forces to the time
Whenever an object experiences uniform circular motion there will always be a net force acting on the object pointing towards the center of the circular path. This net force has the special form , and because it points in to the center of the circle, at right angles to the velocity, the force will change the direction of the velocity but not the magnitude.

Centripetal force can also be expressed in terms of angular velocity. Angular velocity is the measure of how fast an object is traversing the circular path. As the object travels its path, it sweeps out an arc that can be measured in degrees or radians. The equation for centripetal force using angular velocity is:
