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.

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

Newton’s Second Law Definition

Newton’s Second Law of Motion states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.

This fundamental law explains how the motion of an object changes when a force is applied to it. It clarifies that the acceleration of an object is dependent on both the force acting on it and its mass.

Simply put, when a force is exerted on an object, it will accelerate in the direction of that force. The more force applied, the greater the acceleration will be. Similarly, if the object’s mass increases, its acceleration will decrease for a given force.

How to calculate newton’s second law?

How to calculate newton’s second law?

  1. First, determine the force.

    Measure the force acting on the object.

  2. Next, determine the mass.

    Measure the mass of the object.

  3. Finally, calculate the acceleration.

    Using the formula of newton’s second law, calculate the acceleration.


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 objects in motion. These include mass, velocity, and total time.
