The law of inertia states that an object

• Will continue moving at the same velocity unless an outside force acts on it
• That is not moving will not move unless an outside force acts on it
• At rest will remain will at rest unless acted on by an outside force
• Will do all of the above

What is the net force on a truck if one force pushes it forward with 100 newtons and a second force pushes it back with 60 newtons?

• 160 N unbalanced
• 40 N forward
• 60 N backward
• 100 N forward

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

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

• The one with a mass of .78 kg will have the greatest acceleration
• The one with a mass of .52 kg will have the greatest acceleration
• They will both accelerate at the same time.
