State the equation which links gravitational field strength, mass and weight.
weight = mass x gravitational field strength
gravitational field strength = mass x weight
mass = gravitational field strength x weight
mass = gravitational field strength ÷ weight
Which equation links distance, force and work done?
work done = force x distance
work done = force ÷ distance
force = work done x distance
distance = force ÷ work done
Which equation links extension, force and spring constant?
force = spring constant x extension
force = spring constant ÷ extension
spring constant = force x extension
force = spring constant x extension2
