Question

explain net force with suitable examples?​

Answer 1

Answer:

net force is defined as the sum of all the forces acting on an object. net force can accelerate a mass. net force is a term used in a system when there is a significant number of forces

if N is the number of forces acting on a body then the net force formula is given by

F net = F1+F2+F3......+FN

where

F1+F2+F3 are the forces acting on the body

EXAMPLE

1) a toy car is at rest, and a force of 70 N is applied to it. if the frictional force of 20 N then determine the net force

answer is

applied force (Fa) = 70 N

frictional force (Ff) = 20 N

Fnet = Fa+Ff

Fnet = 70-20

Fnet = 50 N

so the net force is 50 N
