When you kick a soccer ball, you are exerting a force on the ball to make it move. A force is described by its strength and its direction. A force’s strength is measured in units called Newtons, named after Sir Isaac Newton. A force is represented by an arrow pointing in the direction of the force, with the length of the arrow indicating the strength of the force. push270 newtonsCombining ForcesNet ForceForces can act in combination and produce what is referred to as net force. When two forces are exerted in the same direction, you calculate net force by adding the two forces together. 100 newtons100 newtonsbalanced forcesnet force = 200 newtons100 newtons100 newtons100 newtonsunbalanced forces200 newtonsBalanced ForcesIf two equal forces are opposed to each other, they tend to cancel each other out. These are called balanced forces. Unbalanced ForcesTwo unequal opposing forces will produce a net force in the direction of the larger force. A force is a push or a pull.
