Which of the following statements correctly describes Newton's first law of motion?

• An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless the object is acted upon by a balanced force.
• An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless the object is acted upon by an unbalanced force.
• An object at rest stays at rest and an object in motion stays in motion with a change in speed and direction unless the object is acted upon by a balanced force.
• An object at rest stays at rest and an object in motion stays in motion with a change in speed and direction unless the object is acted upon by an unbalanced force.

What is the definition of inertia?

• The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction.
• The tendency of an object to move in a straight line with constant speed.
• The tendency of an object to change its state of motion.
• The tendency of an object to accelerate when acted upon by a force.
