Newton's First Law
Newton's First Law says:
An object stays at rest, or if moving, it remains moving at a constant speed and direction, unless acted on by an unbalanced force.
In other words, An object continues its motion, unless an outside force acts on it.
Inertia:
Newton's First Law is also called the Law of Inertia. Inertia is the resistance, reluctance, or opposition to a change in motion. It is measured by mass, which means that more mass is more inertia. More mass means more resistance to a change in motion.
Examples:
An object stays at rest, or if moving, it remains moving at a constant speed and direction, unless acted on by an unbalanced force.

Inertia:
Newton's First Law is also called the Law of Inertia. Inertia is the resistance, reluctance, or opposition to a change in motion. It is measured by mass, which means that more mass is more inertia. More mass means more resistance to a change in motion.
Examples:
- A refrigerator is more difficult to move than an empty box (even on an ice skating rink), because it has more mass and therefore more inertia.
- When riding in a car, if the car stops suddenly you move forward. Why? Because your body is an object in motion, and it has mass, therefore it has inertia.
