Force Calculator
Apply Newton's second law, F = ma, to find force, mass or acceleration. Work out weight from mass and gravity, compare it across planets, and handle driving and resistive forces together.
What you can do
- Force, mass or acceleration from F = ma
- Weight, mass or gravity from W = mg
- Gravity for the Moon and the planets to choose from
- Weight on the Moon, Mars and Jupiter shown side by side
- Resultant force from driving and resistive forces
- Graphs of force against acceleration and weight against mass
