MECHANICAL: Physics Equations on energy, work and power

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

The standard unit of mass is

• g

• kg

• J

• N

The standard unit of force is

• n

• kg

• J

• N
