## Centripetal Force in Sports

Thus, a lb hammer is pulled in (and, therefore, outward simultaneously) with twice the force of an 8-lb one; (ii) is proportional to the square of the velocity. If the hammer’s speed (i.e. the actual, linear speed) is doubled, the centripetal and centrifugal forces increase four-fold. Centripetal Forces The principle of Lean allows participants of different sporting events to create motion throughout a turn while momentarily moving in a circle. Upon a turn, an athlete will naturally lean, in which then the normal force will act at an angle to the vertical. The. Apr 01, · Applications of centripetal forces (i) Motion in a vertical circle. Let us consider a body of mass m tied to one end of the string which is fixed at O and it is moving in a vertical circle of radius r about the point O as shown in Fig. The motion is circular but is not uniform, since the body speeds up while coming down and slows down while going up.

## Examples and Applications of Centripetal and Centrifugal force

Consider a body moving with uniform speed in a circular path. In this case velocity changes only in direction and not in magnitude. Since velocity is changing continuously, therefore the external force must be acting continuously.

The direction of external force is such that only the direction of the velocity changes. This is possible only if the force always acts at right angles to the velocity. The direction of the velocity of the body is along the tangent to the circle at every point, so the external force must act at right angles to the tangents to circle at every point.

Since radius and tangent are always perpendicular to each other, therefore the external force must act along the radius of the circle at every point. In other words, the force is always directed towards the center of the circle at every point. This point is called the centripetal force. When a car takes a turn, the centripetal force is needed to keep it in its curved track, **application of centripetal force in sports**.

The friction between the tires and road provides the needed centripetal force. The car would skid if a force of friction between tires and the road is not enough particularly when roads are wet. This problem is solved by the banking of curved roads, *application of centripetal force in sports*. Banking of road means that the outer edge of a road is raised, *application of centripetal force in sports*.

Imagine a vehicle provide the necessary centripetal force while taking a turn. Thus banking of roads prevents skidding of vehicles and makes driving safe. The dryer of washing machine is basket spinner. It has a perforated wall having large number of fine holes in the cylindrical rotor.

The lid of the container is closed after putting wet clothes in it. When it spins at high speed, the water from wet clothes is forced out through these holes due to lack of centripetal force.

A separator is a high-speed spinner. It acts on the same principle of centrifuge machines. The bowl spins at very high speed causing the heavier contents of milk to move outward in the bowl **application of centripetal force in sports** the lighter contents inward towards the spinning axis.

The cream is lighter than other components in milk. Therefore, skim milk which is denser than cream is collected at the outer wall of the bowl. The lighter part of the cream is pushed towards the center from where it is collected through the pipe. Consider a stone which is tied to a string moving in a circle.

The necessary centripetal force acts on the stone through the string that keeps it to move in a circle. The centripetal reaction that pulls the string outward is called centrifugal force.
