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.

FAQ
What is the importance of Newton’s Second Law in everyday life?
Newton’s Second Law is crucial for understanding how objects move and interact in our daily lives. It helps in designing vehicles, understanding how sports work, and even in calculating the right amount of force needed to move objects of different masses.
How does mass affect the acceleration of an object according to Newton’s Second Law?
According to Newton’s Second Law, the acceleration of an object is inversely proportional to its mass. This means that as the mass of an object increases, its acceleration decreases when the same amount of force is applied, and vice versa.
Can Newton’s Second Law be applied in a vacuum?
Yes, Newton’s Second Law can be applied in a vacuum. In a vacuum, the absence of air resistance allows for a more accurate observation of the law, as the only force acting on the object (assuming no other forces are present) is the force applied to it, making the calculation of acceleration straightforward.
How do velocity changes affect the force applied to an object?
The change in velocity of an object, along with its mass, directly affects the force applied to it. According to the formula F = m * (vf – vi) / t, an increase in the change in velocity (vf – vi) results in a greater force for a given mass and time period. This demonstrates the relationship between an object’s motion and the force exerted on it.
