What is the First Law of Motion

• Acceleration depends on the object's mass and on the net force acting on the object

• If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object

• An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force

• none of the above
