# Force Definition

In **physics**, **force **is defined as an **interaction among two or more objects** that **causes velocity change** in them. Whenever an object is pulled or pushed there is a force acting upon them. However, the objects will not experience the more extended force if the exchange stops. In **mathematical **form, **Force **is defined as the **product of mass into acceleration**, where acceleration is the change in velocity over a specific time. In addition to this, the symbol used to represent force is F, and the SI unit to represent the force is Newton. There are various **types **of force that can be classified: **nuclear force, impact force, centrifugal force, electromagnetic force, gravitational force**, etc.

## Formula of Force

To instantly determine the force generated by an object, you can use the formula listed below:

F = m × a

**Where,**

F = Force

m = Mass of an object (on which force is applied)

a = Acceleration of an object due to force

**Note:**

If you want to calculate force, you can use our Force Calculator.

### Example

For a more precise and clear understanding of the concept, let us solve an example below:

Suppose if a car weighting 1000kg, then find out the net force required to accelerate the car at the velocity of 4 m/s^{2}.

**Given data**

Acceleration = a = 4.00 m/s^{2}

Mass = m = 1000 kg

**To Find**

Force required to move an object = ?

**Solution**

To find out the force required to move an object, we will use the formula listed below:

F = m × a

Putting values in the formula:

F = 1000 × 4 = 4000 N
