The net resultant force acting on an object is equal to what?

When two or more forces are acting on a body, then the total of all the forces which causes the resulting effect is the resultant force or net force. As force is a vector, we need to take the vector sum of all the forces to calculate the resultant.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
