Which of the following best describes Newton's First Law of Motion (Inertia)?

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

• An object accelerates in the direction of the net force applied to it.

• For every action, there is an equal and opposite reaction.

• The acceleration increases.

• The acceleration decreases.

• The acceleration stays the same.

• The object stops moving.
