Many motions, such as the arc of a bird’s flight or Earth’s path around the Sun, are curved. Recall that Newton’s first law tells us that motion is along a straight line at constant speed unless there is a net external force. We will therefore study not only motion along curves, but also the forces that cause it, including gravitational forces. In some ways, this chapter is a continuation of Dynamics: Newton’s Laws of Motion as we study more applications of Newton’s laws of motion.

Uniform Motion: Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time. 6-3 Uniform Circular Motion 113 Review & Summary 118 Problems 119 7 Kinetic Energy and Work 125 7-1 Kinetic Energy 125 7-2 Work and Kinetic Energy 127 7-3 Work Done By The Gravitational Force 131 7-4 Work Done By a Spring Force 135 7-5 Work Done By a General Variable Force 138 7-6 Power 142 Review & Summary 144 Problems 145.

Its wheels also spin rapidly—the latter completing many revolutions, the former only part of one (a circular arc). The same physical principles are involved in each. (credit: Richard Munckton)

This chapter deals with the simplest form of curved motion, uniform circular motion, motion in a circular path at constant speed. Studying this topic illustrates most concepts associated with rotational motion and leads to the study of many new topics we group under the name rotation. Pure rotational motion occurs when points in an object move in circular paths centered on one point. Pure translational motion is motion with no rotation. Some motion combines both types, such as a rotating hockey puck moving along ice.
