The paper “ Centripetal Motion - the Rate of Change of Velocity" is an worthy variant of a lab report on physics. The author names such objectives of the practical as determining the centripetal force existing in a body, finding out the relationship between mass, radiuses, and velocity, to study the motion of moving in a circular manner. Discussion Acceleration refers to the rate of change of velocity, therefore, if a circulating body, there is a change in velocity which implies the body is accelerating. Centripetal acceleration refers to “ the acceleration of a body which is moving in a circular path at a constant tangential speed.

The magnitude of this centripetal force is given by the formula where R is the radius of the path. Considering newton’ s second law of motion is given by the equation below, There is an indication that there must exist a net force on a body moving in a circular motion at a constant speed. This net force is what is referred to as centripetal force which is always in the center of a moving object. Combining the above two equations results in an equation which is used in finding the magnitude of the centripetal force. This experiment involves a mass of an object rotated about an axis having a given radius R.

Materials Springer Hanger, Mass, Clamp, Pulley, Center post pulley. Procedure 1. Put a weight of 1 kg at the end of the rotating platform and adjust the leveling screws in such a way that weighted end of the platform with the third leveling screw. After the apparatus has balanced, remove the 1 kg mass. 2. Take the mass of the hooked mass and record. 3.

Put the hooked mass on the apparatus ensuring it is connected to the string from the center post. 4. Select the radius R. 5. Gently rotate the apparatus while increasing the speed and record the time the mass takes to complete N revolutions. To get an average value of Time, repeat these steps severally.
