Circular motion 3.0 / 5 based on 1 rating ? PhysicsForces and MotionGCSEAQA Created by: CharCreated on: 21-05-13 16:28 When an object moves in a circle, what is it doing? Continuously changing direction 1 of 13 Which means? It is continuously changing velocity 2 of 13 What does changing velocity mean? It is accelerating 3 of 13 What is the acceleration called? The centripetal acceleration 4 of 13 When does the the object only accelerate? When a resultant force acts upon it 5 of 13 What is that force called? The centripetal force 6 of 13 What does this force always act towards? The centre of the circle 7 of 13 What happens if the centripetal force stops acting? The object will continue to move in a straight line at a tangent to the circle 8 of 13 The centripetal force increases by how many things? 3 9 of 13 By, the mass of object... Increases 10 of 13 The speed of the object... Increases 11 of 13 The radius of the circle... Decreases 12 of 13 What force provides the centripetal force? Gravitational force or tension or electric force 13 of 13
