1. The single force that has the same effect as all the forces acting on an object; the vector sum of all forces acting on an object
The net force on the object is zero when it moves at constant velocity.
A força resultante sobre o objeto é zero quando ele se move com velocidade constante.
2. In physics, the combined effect of multiple forces acting in different directions on a body
To calculate the net force, we must add all forces vectorially.
Para calcular a força resultante, devemos somar todas as forças vetorialmente.
