Example:
4N------object----------6N
it moves to the left because 6 is greater, if it was 4n and 4n it would stand still
answer=2N (6N-4N)
if it was
4N-------
OBJECT you would need to add in this situation
4N------- answer=6N
Explantion:
Net force when a body is in motion: When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = Fa + Fg + Ff + FN. Where,
