Newton's Third Law of Motion
It's simple
For every reaction,
There is an EQUAL, but OPPOSITE reaction
But what exactly does that mean?
Let's take a closer look.
Third Law
The force of one object exerted on another.
According to Newton these forces will always act in equal but opposite pairs.
It's the LAW!
Force Pairs
Action
Just how common is
Newton's 3rd Law?
Reaction
It is used everyday by everyone
*Remember*
These will be equal and opposite
of each other
From walking,
to jumping,
to flying,
and more...
Let's keep it simple
When jumping, you push down on the ground.
As a result, the Earth pushes back and propels you upward.
Any
Questions?
Just remember,
with EVERY action there is an equal but opposite reaction.
It doesn't matter if the objects are at rest or not.
Ever rode a skateboard?
What happens when you step off of it?
What about objects at rest?
When sitting on a chair, there are two forces at work.
Force of Chair
Force of You
Let's start
the experiment!
But Wait...
The Earth doesn't
actually "push" back,
or does it?
Actually, YES, it does!
It's all
relativity!
We can't see Earth push back when we jump because it's mass is so large.
However, we CAN see the skateboard roll back.
