# Newton's Laws of Motion/Physics

#### Terms in this set (...)

force
a push or pull exerted on an object
unbalanced force
forces that produce a non-zero net force, which changes an object's motion
balanced force
when the net force on an object is zero and produces no change in the motion of the object
net force
the overall force acting on an object after all the forces are combined
inertia
the tendency of an object to resist a change in motion
Newton's First Law
an object at rest will stay at rest and an object in motion will stay in motion at the same speed and in the same direction until acted on by an unbalanced force; known as the law of inertia
Newton
Measurement of a Force.
friction
a force that opposes the motion of objects that touch as they move past each other
gravity
A force that pulls objects toward each other
Newton's Second Law
the greater the mass of the object, the more force it will take to accelerate the object (F=ma)
air resistance
force that opposes the motion of objects that move through the air
Newton's Third Law
for every action there is an equal and opposite reaction
acceleration
change in velocity
velocity
the speed of an object in a particular direction
Fg
Force /gravity
Fa
Force/applied
Ft
Force/tension
Fn
Force/normal
vector
A quantity that has magnitude and direction
Potential Energy
Stored Energy
Kinetic Energy
Energy of motion
Elastic potential energy
