Force+by+McKenna

=FORCE= A force is a push, or pull, or any action that has the ability to change motion.


 * Forces may be described as pushes or pulls created by gravity or magnetism.
 * Forces acting on three dimensional objects may cause them to rotate or change direction.
 * Since antiquity(long time ago, old) scientists have used the concept of force in the study of moving and non-moving objects.
 * F=MA or force=mass x acceleration
 * Acceleration is produced when a force acts on a mass. The more the mass the greater the amount of force needed to accelerate the object.

F= Newtons(n) M=Kilograms(kg) A=Meters per second squared(m/s²)

Questions:
 * 1) When a force is exerted on an object, does a larger force always produce greater change in the object's momentium than a smaller force does? Explain.
 * 2) A desk weighs 500 N with gravity applying that force downward. If you apply 275 N upward force and a friend helping you applies 275 N upward force, what is the net force applied?
