# Newton’s Second Law Calculator

Enter the mass of an object, the initial and final velocities, and the change in time of an object under acceleration to calculate the force.

## Newton’s Second Law Formula

The following equations are used by the calculator above to determine the force acting on an object under acceleration. Newton’s Second Law states that the acceleration of an object is equal to the force acting on that object divided by the mass.

a = F / m

• Where a is acceleration
• F is force
• m is mass

Since we know that acceleration is the rate of change of velocity over time, then we can rearrange the equation to the following:

F = m * (vf – vi) / t

• Where F is force
• m is mass
• vf is final velocity
• vi is initial velocity
• t is change in time

## FAQ

What is newton’s second law?

Newton’s second law states that the force acting on an object is equal to the force divided by the mass.

How can newton’s second law be used?

Using the base equation of a = F/m, many things can be calculated for in objects in motion. These include mass, velocity and total time.
