Answer:
You determine the net force of an object by adding up all of the individual forces.
Explanation:
If N is the number of forces acting on the body, the net force formula is:
[tex]F_{Net}[/tex] = [tex]F_{1}[/tex] + [tex]F_{2}[/tex] + [tex]F_{3}[/tex] ....+ [tex]F_{N}[/tex]
Where [tex]F_{1}[/tex], [tex]F_{2}[/tex], and [tex]F_{3}[/tex] as forces acting on a body.
When a body is at rest, the net force formula is given by
[tex]F_{Net}=F_{a}+F_{g}[/tex]
Fa = Applied force and
Fg = Gravitational force.
Example:
A truck is standing still and a force of 70 N is applied on it. If the frictional force is 20 N, then what will be the net force?
Solution:
Given
Applied force Fa = 70 N
Frictional force Ff = 20 N
The net force formula is given by
FNet = Fa + Ff
FNet = 70 + (-20)
FNet = 50 N
Therefore, the net force is 50 N
