AQA further physics - higher P3 topic 1 a further physics quiz on the higher topic 1 of AQA P3-turning forces 4.0 / 5 based on 1 rating ? SciencePhysicsGCSEAQA Created by: IsabelleCreated on: 30-09-10 09:33 What is the centre of mass? the point where the mass is thought to be the most concentrated 1 of 13 When an object is moving in a circle at a constant speed if the radius of the circle is decreased....... the centripetel force decreases 2 of 13 The gravitational force is bigger when.... the mass is bigger. 3 of 13 The gravitational force is smaller when.... the distance is bigger. 4 of 13 The further away a planet in orbit is... the less speed it needs 5 of 13 What provides the centripetal force that keeps planets and satellites moving in their orbits? gravity 6 of 13 How long does a geostationary orbit last for? 12mounth 7 of 13 What is the moment of a force? the turning effect of a force 8 of 13 Moment is measured in Newton metres (Nm)? True 9 of 13 If the object is at equilibrium....The sum of all the clockwise moments about any point= the sum of all the anticlockwise moments about that point 10 of 13 The bigger the base of an object.... the more stable the object 11 of 13 When an object is moving in a circle at a constant speed... it is accelerating continuously and a centripetel force is present 12 of 13 As the mass or speed of the object moving in a circle at a constant speed increases..... the centripetel force increases 13 of 13
