A force is a push or pull
Forces are described by there strength, but also the direction
Overall force of an object is called the net force
When there is a net force on an object it is an Unbalanced Force
An Unbalanced force that acts upon and object will change the
object’s motion.
Equal forces that act on an object in opposite directions is called
balanced forces
Balanced forces acting on an object will not change the object’s
motion
Mass is the amount of matter in an object
VOCABULARY KEY:
First Law of Motion
The first law of motion shows that an object at rest
will stay at rest. Then an object in motion at a
consistent speed will continue to move unless it is
acted upon by a unbalanced force.
Another name fore the First Law of Motion is The Law
of Inertia.
Second Law of Motion
The second law says that heavier objects require
more force than lighter objects. It then says that
force is equal to mass times acceleration. (F=MA)
M=mass, A=Acceleration and F=force.
Third Law of Motion
For every action there is an equal and opposite
reaction.
