Back

gravity

Front

the force (in Nkg-¹) that pulls objects towards the centre of the earth at a rate of 10 ms-²

Back

balanced force

Front

forces on an object that combine to give a zero net force and do not change the motion of the object

Back

net force

Front

the overall force acting on an object after all the forces are combined

Back

pressure

Front

how much force is put onto a particular area defined as the amount of force exerted per unit area of a surface

Back

the unit for force

Front

Front

force that opposes motion of an object when two surfaces are in contact

Back

the rearranged formula for force used to calculate mass

Front

m=F/a

Back

Force

Front

A push or pull that acts on an object
