Frank jumps into a raft in his pool. As he jumps, he moves forward as the raft moves in the opposite direction. Which answer best describes the correct answer.

• The 1st law because a body at rest tends to stay at rest
• The 3rd law because for every action there is an equal and opposite reaction
• The 2nd law because as the mass increases so does the force
• The 4th law because I was not paying attention in class when we went over this topic.

• Teacher sitting in a chair
• Book resting on desk

Conservation of Matter is...

• When matter changes state, the total amount of matter is different.
• When matter changes, the mass stays the same.
• When matter changes into a liquid, the mass decreases. 
• When matter changes into a solid, the mass increases.
