FORCE AND MOTION

�Force: a force is a push or pull on an object. �Net Force: the combination of all the forces placed on an object �Force is measured in Newtons

�Balanced �When Forces forces placed or exerted on an object are equal (balanced) the motion of the object doesn’t change

�Unbalanced Forces �Sometimes, more force is applied to one side of an object. �This results in unbalanced forces, which causes __________. MOTION �

� If the _________ is greater than zero, motion occurs. � The direction of movement is determined by the greater force.

25 N In the diagram above: Will the box move? __________ If yes, which direction will it move? __________ Are the forces balanced or unbalanced? ___________

50 N 25 N In the diagram above: Will the box move? __________ If yes, which direction will it move? __________ Are the forces balanced or unbalanced? ___________

30 N 15 N 25 N In the diagram above: Will the box move? __________ If yes, which direction will it move? __________ Are the forces balanced or unbalanced? ___________ What is the net force on the box? _______
