- Newton's first law of motion was called the law of inertia
- Newton's first law states that if a object is in motion it stays in motion at the same speed and direction
- The second part of the law states that if a object is at rest it stays at rest
- Only a unbalanced force can make a object move
- Objects will not move unless a push or pull is occurred
- The only way an object will move is if an unbalanced force acts on it. This will add inertia to the object. That means an object will have inertia
- When an object is at a constant speed and an unbalanced force is acted on it the objects velocity will change
- Inertia is the tendency of an objects resist to changes in motions
