mass – the amount of material in an object measured

air resistance – the force that air exerts on a moving

in grams (g)

object

newtons – the units used to measure forces (N)

balanced – when the forces acting on an object are

opposite and equal such that the object does not move

speed – how fast an object is moving

force – a push, pull, twist or turn – gravity, friction and

stationary – not moving

upthrust are all examples of forces

unbalanced – when one force acting on an object is

force diagram – a diagram which represents forces and

greater than the other forces, the object moves in

the directions they are acting with arrows

the direction in which that force is acting

forcemeter – a device used to measure forces

upthrust – a force in water which pushes upwards

(sometimes called a newtonmeter)

water resistance – the force that water exerts on a

moving object

friction –is the force between two moving surfaces

weight – the force downward on an object caused by

gravity – the force that causes all objects to fall to the

gravity

ground
