Demonstrate circular motion 3. Define centripetal force 4. Define angular velocity 5. Derive v= r ω 6. Define centripetal acceleration Outline the factors on which centripetal force 7. depends Use a = and F = to perform calculations 8. rω2 mrω2 Past Exam Questions: Define angular velocity. Derive the relationship between the velocity of a particle travelling in uniform circular motion and its angular velocity. A particle travels at a constant speed of 10 m s-1 in a circle of radius 2 m. What is its angular velocity? A student swings a ball in a circle of radius 70 cm in the vertical plane as shown. The angular velocity of the ball is 10 rad s–1. What is the velocity of the ball? How long does the ball take to complete one revolution? Define centripetal force. Give an expression for centripetal force.
