Whether it is sports car racing or track and field, baseball running or ice-skating, the motion of objects in circles is a common observation of sports viewers around the world. Like any object moving in a circle, the motion of these objects that we view from the stadium bleachers or watch upon the television monitor are governed by Newton's laws of motion.

Their circular motion - however brief or prolonged they may be - is characterized by an inward acceleration and caused by an inward net force. The mathematical analysis of such motions can be conducted in the manner presented earlier in Lesson 2. In this part of Lesson 2 we will investigate a variety of applications of circular motion principles to the world of sports and use Newton's laws to mathematically analyze such motions.

The emphasis will not be upon an investigation of the details of every possible sport, but rather upon learning how to apply some general principles so that they can subsequently be applied to every sport. Making the Turn The most common example of the physics of circular motion in sports involves the turn.

It could be a halfback in football making a turn around the corner of the line. Or it could be a softball player running the bases and making a turn around second base. Or it could be a bobsled in the Olympic games making a turn around a corner on the track. Whatever turning motion it happens to be, you can be sure that turning a corner involves circular motion principles.

Now for certain not all turns involve a complete circle; nor do all turns have a perfectly circular shape.

Some turns are only one-quarter of a turn - such as the fullback rounding the corner of the line in football. And some turns are hardly circular whatsoever.

Nonetheless, any turn can be approximated as being a part of a larger circle or a part of several circles of varying size. A sharp turn can be considered part of a small circle. A more gradual turn is part of a larger circle.

Some turns can begin sharply and gradually change in sharpness, or vice versa. In all cases, the motion around a turn can be approximated as part of a circle or a collection of circles.

The diagram below depicts a variety of paths that a turn could make. Because turning a corner involves the motion of an object that is momentarily moving along the path of a circle, both the concepts and the mathematics of circular motion can be applied to such a motion. Conceptually, such an object is moving with an inward acceleration - the inward direction being towards the center of whatever circle the object is moving along.

There would also be a centripetal force requirement for such a motion. That is, there must be some object supplying an inward force or inward component of force. When a person makes a turn on a horizontal surface, the person often leans into the turn.

By leaning, the surface pushes upward at an angle to the vertical. As such, there is both a horizontal and a vertical component resulting from contact with the surface below. This contact force supplies two roles - it balances the downward force of gravity and meets the centripetal force requirement for an object in uniform circular motion.

The upward component of the contact force is sufficient to balance the downward force of gravity and the horizontal component of the contact force pushes the person towards the center of the circle. This contact force is depicted in the diagram below for a speed skater making a turn on ice.

The physics of sports has broad applications, and is useful for boosting performance in a variety of athletic disciplines. A lot of the time, good athletic performance is based on proper control and coordination of movement.
