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.

Which of the following explains the difference between speed and velocity?

• One has motion, and the other does not.
• One has direction, and the other does not.
• One involves time, and the other does not.
• One involves acceleration, and the other does not.

Acceleration is caused by a force acting on a mass.
