1. Inertia Newton’s First Law

2. Newton's First Law What does that means?
An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What does that means?

3. This is also called INERTIA
It means that…
An object in motion wants to stay in motion, and an object at rest wants to stay at rest.
This is also called INERTIA

4. The car is at rest, and it is going to stay at rest
until a force gives it a push.

5. Now that is moving, it will continue to move until another force stops it.
Friction

6. The best place to test inertia is in Space, why?
In outer space there is no air, or anything else to create friction. So moving objects will keep moving forever, and objects that aren't moving will stand still forever.
