Newton's Second Law Calculator
📐 Physics of Matter. Use the Newton's second law formula to find force, mass, acceleration: pick the value you want, type the others, and the answer updates as you go.
Force20 N
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Force | N |
| Mass | kg |
| Acceleration | m/s² |
Worked example
Find the force when Mass = 2 kg, Acceleration = 10 m/s².
Using F = ma: Force = 20 N.
Frequently asked questions
What is the formula for Newton's second law?
F = ma.
What do the letters stand for, and what units are used?
Force in N, Mass in kg, Acceleration in m/s².
How do you calculate force?
Put the values into F = ma. For example, with Mass = 2 kg, Acceleration = 10 m/s², force = 20 N.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (force, mass, acceleration) and fill in the others: it rearranges the formula for you.
