The tendency of an object at rest to stay at rest unless it is acted upon by a force is called ___________________.

• inertia
• motion
• gravity
• lubricant

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

If you double the mass of an object with the same force apply on it, the acceleration will

• double
• cut in half
• the same
• zero
