A 10-kg box is sitting at rest on a table. What is the net force acting on the box?

the net force /resultant force is 0N

Explanation:

this is because newton's first law states that when there was no resultant force, the object will continue in its state of rest or uniform motion in a straight line.

as a result, the box is at rest. this the net for certain which is the resultant force is 0N, this doesn't mean that there is no force, it is just that the total force (after subtracting) is 0N

hope this helps,

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
