Can someone help me with this physical science questions? (Inertia)?

1. A student claims that when a ball rolls down a hill, it violates Newton's 1st law of motion, since a body at rest tends to stay at rest. Is that student wrong? Why or why not?

2. Why does the ball roll down in the first place?

3. Aristotle said that every object has a resting place, or a place it will go to rest. How does it "DIFFER" from Newton's First Law of Motion?

4. How does the inertia apply to the game of football?

5. Mr. Will was driving home with a pie for his wife. He placed the pie on the back seat. After a sudden stop, the pie smashed into the front seat. What did he do wrong?
