MRS. WHARTON’S SCIENCE CLASS The Nature of Force

Force Force- a push or pull Forces are described not only by how string they are, but also by the direction in which they act/. The strength of force is measured in NEWTONS. ( Isaac Newton)

Net Force The overall force on an object Found by combining all the forces acting on an object  When two forces act together they are added  When two forces work against one another they are combined subtracting the smaller from the larger.

Unbalanced Forces Can cause an object to start moving, stop moving or change direction Unbalanced forces acting on an object will change the object’s motion

Balanced Forces Equal forces acting in opposite directions. Balanced forces acting on an object will not change the object’s motion.
