Circular Motion Figure 1: Ferris Wheel Circular motion is a motion of any object that moves in a circle, or making a circular path . Simple examples of this motion are: 1)The earth orbiting the Sun; the earth acts as the object 2) The person in a Ferris Wheel; the person acts as the object 3) Hammer throwing; the metal ball acts as the object Before this we have learned linear motion and projectile motion from Chapter 2. So now, for your information, we are going to learn one more type of motion in Chapter 6 that is circular motion . This motion is of course not the same as the linear motion. If you could recall, linear motion is the motion in a straight line. If in linear motion , we have the term displacement , velocity and acceleration , so do the circular motion :) The names are also a bit different as you can see from the table below: LINEAR MOTION CIRCULAR MOTION Displacemenet , s Angular Displacement, θ Velocity
