Which of Newton’s laws of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by an unbalanced force?

The first law of motion, also known as Newton's law of inertia, states that an object at rest will remain at rest, and an object in motion will continue to move in the same direction and at the same speed, unless acted upon by an unbalanced force.
