Uniform Circular Movement

OBJECTIVES

Circular movement can be seen in many gadgets which surround us; engines, the hands of a clock and wheels are some examples. This teaching unit presents the characteristic magnitudes of Uniform Circular Movement and revises the concepts of arc and angle.

This unit concludes the study of movement which began in the previous three units:

Moving bodies, Trajectory and Displacement and Rectilinear Movements

To understand the kinematic characteristics of Uniform Circular Movement.

To understand the meaning and utility of the radian for describing this movement.

To express velocities in rad/s, r.p.s. and r.p.m. and to convert them from one to another.

To understand the meaning of linear and angular magnitudes.

To transform linear magnitudes into angular ones and vice versa.

	Arc, angle and radius
	How many radians are there in a circumference?
