What is Newton's first law
What is an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Define inertia
What is the tendency of an object to resist being moved or, if the object is moving , to resist a change in speed or direction until an outside force acts upon an object
