Physics Paper 2If the speed at which an object moves through a fluid increases, will the size of the frictional force that acts on it increase, decrease or stay the same? >>> increaseIs tension a contact or non-contact force?>>> contactWhat name is given to the point at which the mass of an object may be considered to be concentrated?>>> centre of mass/ centre of gravityObject 1 has a low centre of mass and Object 2 has a high centre of mass. Which object will be more stable?>>> object 1True or false? If the vertical line through an object's centre of mass falls within its base of support then the object will topple over.>>> falseWhat is the SI unit for mass? Give the full name, not the symbol.>>> kilogramWeight is the downward pull of __________ on mass. What one word completes the sentence?>>> gravityWhat is the main force that must be overcome in order to push an object along a horizontal surface?>>> frictionA lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m. How much work is done to move the lift this height?>>> 15,000Look at the equation shown below. It can be
