... • Newton’s third law is that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. • In other words, all forces act in pairs. • Action and reaction forces are present even when there is no motion. ...

Unbalanced Force = Net Force
... As we have said before, a net force is the sum of all forces acting on an object. Look at the picture of the red plane. In this example, the difference between drag and thrust is 15 Newtons, to the left. This net force is capable of accelerating (slowing down) the plane. Net forces always accelerate ...
