How to Calculate Force Acting on a Body?

According to Newton's second law of motion, force is nothing but the rate of change of momentum. Get the detailed steps to find the force acting on a body in the following sections.

  • Observe the initial velocity, final velocity, time change and mass of the object from the question.
  • Find the difference between final velocity and initial velocity.
  • Divide the velocity difference by the time difference which is acceleration.
  • Multiply the object mass with the acceleration to get the force.

What is Newton's Second Law of Motion?

Newton's Second Law states that the acceleration of an object depends on the object mass and the amount of force applied on it.

Its formula is F = m * a

a = (Vf - Vi)/Γû│t

Here,

F is the force acting on a body

a is the acceleration

Vf is the final velocity of the object.

Vi is the initial velocity of the object

Γû│t is the time difference.

Example

Question: A 1 kg object accelerated at a constant 5 m/sec². Estimate the net force required to accelerate the object.

Solution:

Given that

Mass of the object m = 1 kg

Acceleration a = 5 m/sec²

As per Newton's second law of motion,

F = m * a

F = (1 kg) * (5 m/sec²)

= 5 Newton

Therefore, the force acting on a body is 5 N.

Frequently Asked Questions on Newton's Second Law Calculator

1. Define Newton's Second Law?

Newton's second law of motion states that the acceleration of an object depends on two variables such as the mass of the object and the force acting on the object. The acceleration is directly proportional to the force and inversely proportional to the mass of the object.


2. Write examples of Newton's second law?

 

  • In a golf game, the acceleration of the ball is proportional to the force with which it is hit by the golf stick.
  • When an object falls down from a certain height, the acceleration increases due to the gravitational force.
  • Pushing a truck is difficult than pushing a car with the same amount of force and the mass of the truck is heavier than the mass of the car.

 


3. How do you find acceleration in Newton's second law?

Newton's second law of motion formula is F = m * a. From this, acceleration a = F/m. So, you can find the acceleration by dividing the force acting on a body by the mass of the object.


4. Mention the applications of Newton's Second Law?

The applications of Newton's second law is two people walking, pushing a cart, kicking a ball etc.
