Centre of mass 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: CharCreated on: 21-05-13 15:28 What is the centre of mass? The point it is thought to be most concentrated 1 of 12 Where will any object that is freely suspended come to rest with its centre of mass? Directly below the point of suspension 2 of 12 What is the object then in? Equllibrium 3 of 12 What is the first step to find the centre of mass of a thin irregular sheet of material? Suspend thin sheet from pin (held in a clamp stand) 4 of 12 Why would the answer to the first step be freely suspended? Because it is able to turn 5 of 12 Second step after it comes to rest? Hang a plumbline against the sheet 6 of 12 3rd step? Hang the sheet with the pin at another point 7 of 12 4th step? Repeat the procedure! 8 of 12 Where is the centre of mass found from this experiment? Where the lines marked the position of the plumbline cross 9 of 12 What does the position of the centre of mass depend on? The shape of the object (which sometimes lies outside the object) 10 of 12 How do you find the centre of mass on a symmetrical shape? Along the axis of symmetry 11 of 12 What happens if the symmetrical object has more than one axis of symmetry? Centre of mass is where the axes of symmetry meet 12 of 12
