Law on inertia
An object at rest stays at rest. An object at motions stays at motions at a constant speed and direction.
Inertia
When an object resists a change in motion
Inertia is reliant on
Mass
Another term for newtons second law
Acceleration
Newtons second law
When an unbalanced force acts on an object it accelerates
More force= more acceleration
Less force= less acceleration
Force =
Mass times acceleration
Nickname for newtons third law
Action-reaction
Newtons third law states..
Every action has an opposite reaction
