Given that, weight = mass x g then
mass = weight x g
mass = g ÷ weight
mass = weight ÷ g
Given that, weight = mass x g then
g = weight x mass
g = mass ÷ weight
g = weight ÷ mass
Given that, Work = force x distance then
force = work x distance
force = distance ÷ work
force = work ÷ distance
Given that, Work = force x distance then
distance = work x force
distance = force ÷ work
distance = work ÷ force
Given that, Work = force x distance AND weight = mass x g, then
distance = work x mass x g
distance = mass x g ÷ work
distance = work ÷ (mass x g)
distance = (work x g) ÷ mass
Given that, Work = force x distance AND weight = mass x g, then
mass = work x distance x g
mass = distance x g ÷ work
mass = work ÷ (distance x g)
mass = (work x g) ÷ distance
Given that, Power = work ÷ time then
work = power x time
work = time ÷ power
work = power ÷ time
Given that, Power = work ÷ time then
time = power x work
time = work ÷ power
time = power ÷ work
