Force Calculator
Newton's second law of motion states that the net force on an object equals its mass multiplied by its acceleration, written F equals m times a. This calculator lets you solve for any of the three quantities by entering the other two. Provide mass in kilograms and acceleration in meters per second squared to get force in newtons, or work backward to find the acceleration a known force produces or the mass being accelerated. It is a fundamental relationship in mechanics that underlies everything from car braking distances to rocket thrust, so it comes up constantly in physics homework and engineering estimates. The result appears as soon as you press calculate, and every computation is done locally in your browser with nothing sent to any server.
How to use Force Calculator (F = ma)
- Enter any two of force, mass, and acceleration.
- Leave the unknown field blank.
- Read the calculated third value in newtons, kilograms, or meters per second squared.
Frequently asked questions
What law does this force calculator use?
It uses Newton's second law, force equals mass times acceleration, written F=ma. Enter any two values to solve for the third.
What units does it expect?
Mass is in kilograms, acceleration in meters per second squared, and force in newtons. One newton equals one kilogram meter per second squared.
Can it solve for mass or acceleration?
Yes. Enter force with either mass or acceleration and the calculator returns the missing quantity.
What is Force Calculator (F = ma)?
Newton's second law of motion states that the net force on an object equals its mass multiplied by its acceleration, written F equals m times a. This calculator lets you solve for any of the three quantities by entering the other two.
