Weight

• weight = mass × gravitational field strength

• how many kg

• weight = g / mass

Work done

• work done = force

• work done = force × distance

• work done = distance / force

Force applied to a spring

• force = how many kg

• force = length of spring x spring constant

• force applied to a spring = spring constant × extension

Moment

• moment of a force = force × distance

• moment = force x distance squared

• moment = force / distance

Pressure

• pressure = force x area

• pressure = force / area

• pressure = area / force

Distance

• distance travelled = speed × time

• distance = speed / time

• distance = time / speed

Acceleration

• acceleration = change in speed

• acceleration = velocity x time

• acceleration = velocity / time

Force

• force = mass / acceleration

• resultant force = mass × acceleration

• force = acceleration / mass

Momentum

• momentum = mass × velocity

• momentum = velocity / mass

• momentum = mass / velocity

Momentum

• momentum = mass × velocity

• momentum = velocity / mass

• momentum = mass / velocity
