Net Force Formula

Net Force Formula

Small Description: Net force is the summation of total forces acting on the given object. This is the total acceleration of the object against its mass.

When there is the action of numerous forces along the same plane on the object subjected we quote the term net force formula. This is the algebraic summation  of all the forces acting on the object. For example, for one-newton force, there should be a complete summation of one metre square per second acceleration against one-kilogram mass.

Formula

As this is the average of the total number of forces acting on it,

Fn=F1+F2+F3+……FN

In case when we assume the subjected body is at rest,

Fn=Fa+Fg

Here the Fa is the force that is being applied over the object while Fg is the gravitational force experienced by the object, in the earth,

Fg=Mg, where g is the gravitational constant in earth equals the value of 9.8 meters square per second 

On the whole, if we find the object is subjected to multiple forces such as Kinetic, gravitational, acceleration, etc,

Then net force formula is stated by the,

Fnet=Fa+Fg +FN +Ff

Here the equation stands for,

Fa is the applied force

Fg is the gravitational force experienced by the object 

F is the amount of force of friction experienced by the object 

Fn is the amount of normal force applied to the object

Solved Examples 

1. There are two teams playing tug of war, team 1 show the force of 45 newton while second team shows the force of 30 newton what is the net force acting on the rope,

F1 = 45 newton 

F2= -30 newton 

Fnet =F1 +F2

Fnet = 45 -30 =15 newton

2. A car gets stuck in the mud and there are four people who force the car to move out of the mud in the right direction and their forces are 1N ,5N 7N 10N what is the net force 

F1 =1N

F2 =5N

F3 = 7N

F4  =10N

Fnet =F1+ F2+ F3 +F4

Fnet = 1+5+7+10 =23 newton
