what is the net force on an object

Question

Suppose two 4 newton forces act on an object in the same directions

Answer 1

Hi Rita,

Forces acting in the same direction simply add together, so these two forces combine to make 8 N of force. If there are no other forces such as gravity acting on the object then 8N is the net force.

Answer 2

Let the direction be x (x-axis) F₁ = 4 N ; F₂ = 4 N. The net force on that object is F₁ + F₂ = 8 N in the same direction.Basically, you're adding 2 vectors. In this case, 2 vector-forces.
