Transcript Newtown*s Laws of Motion

 1st
law-An object at rest will stay at rest, and
an object in motion will stay in motion at
constant velocity, unless acted upon by an
unbalanced force.
 2nd Law-Force is equal to the mass times the
acceleration. (F=ma)
 3rd Law-For every action, there is an equal
and opposite reaction.

This law states that an object, at rest or
moving, will continue that action until
stopped or moved by any force greater
than its own.
This carton of ice cream will stay
on that counter FOREVER until
acted upon by any force. Maybe
it’s someone picking it up to eat or
a tornado of cats knocks it off the
shelf.
If something is
airborne, it
will stay
moving until
acted upon
by a force.
(On Earth
this force
will most
likely be
gravity. )
This baseball will stay in the air until
a force acts on it. It would most
likely be gravity, but who knows,
maybe God wanted to push it back
down for that centerfielder to make
the winning out.

Inertia is defined as the tendency of a body
to resist acceleration, remain at rest if at
rest, the tendency of a body in straight line
motion to stay in motion in a straight line
unless acted on by an outside force.
This is stated in the first law.
When riding in a car, you body experiences inertia. If you are traveling
at 50 MPH and a deer runs out in the road, you must hit the brakes to
avoid hitting it. Although the car is decelerating your body wants to
continue moving at 50 MPH that’s why you feel the jerk forward.
6 kg
F=(6kg)(9.81m/s/s)
F=59 N
4 kg
(9.81m/s/s)
F=(4kg)(9.81m/s/s)
F=39 N
Newton’s second law proves that different mass accelerate to the
Earth at the same rate but with different forces.

The faster we move the more we produce.
Much like school or careers, the more we
learn and the quicker we do it, more force
and power comes out of it. Getting good
grades will give you more force and power
to do what you want in life.

For every action, there is an equal and
opposite reaction.
=
What comes around goes around.
The amount of force that the
monkey is exerting down on
the ground is exactly equal to
the force that the ground
exerts back up on the monkey.
This keeps the monkey in
place from going up or down.
The gravity is exactly equal to
the normal force of the
ground.
Birds depend on Newton's Third Law. When the bird’s
wings push down through the air, the air pushed back
up into the wings with the same amount of force giving
the bird the boost it needs to fly
When you walk from room to
room in school, you are
pushing down on the floor
with a certain amount of
force. In response to this, the
floor pushes back up onto
you with the same amount of
force you’re exerting onto
the floor. Without this
equilibrium of force, we
would either float around or
sink through the ground.
Have you ever heard the saying “Treat
others the way you want to be treated.”
 Or “What comes around goes around.”

This is a very easy way to look at this law.
Whatever you do, physical or not, there will
ALWAYS be a reaction to your action.
Think about moving furniture. When you
push a desk, it will push back on your
hand with the exact same amount of force
that you are pushing on it.
