SciencePhysicsGCSEAQA Created by: IsabelleCreated on: 30-09-10 09:47 What is the centre of mass? the point where the mass is thought to be the most concentrated 1 of 13 The gravitational force is bigger when.... the mass is bigger. 2 of 13 What provides the centripetal force that keeps planets and satellites moving in their orbits? gravity 3 of 13 The gravitational force is smaller when.... the distance is bigger. 4 of 13 The further away a planets orbit... the slower it travels 5 of 13 How long is the orbit of a geostationary object? 24 hours 6 of 13 What is the moment of a force? the turning effect of a force 7 of 13 Moment is measured in Newton metres (Nm)? True 8 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 9 of 13 The bigger the base of an object.... the more stable the object 10 of 13 When an object is moving in a circle at a constant speed... it is accelerating continuously and a centripetel force is present 11 of 13 As the mass or speed of the object moving in a circle at a constant speed increases..... the centripetel force increases 12 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 13 of 13
