Answer 2

Overview of Non-Uniform Circular Motion

Non-uniform circular motion denotes a change in the speed of a particle moving along a circular path.

LEARNING OBJECTIVES

Explain when a particle undergoes non-uniform circular motion

KEY TAKEAWAYS

Key Points

In non- uniform circular motion, the size of the velocity vector (speed) changes, denoting change in the magnitude of velocity.

The change in speed has implications for radial ( centripetal ) acceleration. There are two possibilities: 1) the radius of the circle is constant; or 2) the radial (centripetal) force is constant.

In either case, the angular velocity in non-uniform circular motion is not constant, as  

ω

=

v

r

, and  

v

varies.

Key Terms

radial: Moving along a radius.

centripetal: Directed or moving towards a center.

What do we mean by non-uniform circular motion? The answer lies in the definition of uniform circular motion, which is a circular motion with constant speed. It follows then that non-uniform circular motion denotes a change in the speed of the particle moving along the circular path. Note especially the change in the velocity vector sizes, denoting change in the magnitude of velocity.
