Newton's Laws
Station 1 (slides 3-6):
1) What does Newton's First Law mean for objects that are NOT moving?
2) What does Newton's First Law mean for objects that ARE moving?
3) What kind of force would cause the golf ball to move off the tee?
4) What slows the golf ball down to a stop?
Station 2 (slides 7-8):
5) What is inertia?
6) How are inertia and mass connected?
7) According to Newton's First Law, why should you wear a seat belt?
Station 3: Dr. Skateboard: Newton's First Law
Station 4 (slides 9-11):
8) What does acceleration depend on?
9) What does the net force on an object depend on?
10) What are the formulas to solve for acceleration and to solve for force? (Also, draw the magic triangle!)
11) How does mass affect acceleration?
12) How does force affect acceleration?
Station 5: Dr. Skateboard: Newton's Second Law
Station 6 (slide 12):
13) What is the unit used for force?
14) What is a Newton?
Station 7 (slides 13-14):
15) Copy the problems on both slides.
Station 8:
Solve these problems. Be sure to use the correct units!
16) What acceleration will result when a 12 N net force applied to a 3 kg object?
17) How much force is needed to accelerate a 66 kg skier 1 m/sec2?
18) A net force of 16 N causes a mass to accelerate at a rate of 4 m/s2. What is the mass?

We'll do notes on Newton's 3rd Law and the Law of Conservation of Momentum!
Newton's Laws in Action:
Directions: Mark each of the following situations as an example of Newton’s First (1st ), Second (2nd ) or Third (3rd ) Law on the blank before the number. Then explain in complete sentences how the situation is an example of that particular law.

- A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them.
Explain Your Answer: - A person’s body is thrown outward as a car rounds a curve on a highway.
Explain Your Answer: - Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket accelerates in an opposite direction.
Explain Your Answer: - A picture is hanging on a wall and does not move.
Explain Your Answer: - A person not wearing a seatbelt flies through a car window when someone slams on the breaks because the person’s body wants to remain in continuous motion even when the car stops.
Explain Your Answer: - Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.
Explain Your Answer: - A soccer ball accelerates more than a bowling ball when thrown with the same force.
Explain Your Answer: - A soccer player kicks a ball with their foot and their toes are left stinging.
Explain Your Answer: - A student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up.
Explain Your Answer: - Two students are in a baseball game. The first student hits a ball very hard and it has a greater acceleration than the second student who bunts the ball lightly.
Explain Your Answer:
Newton's Law Paragraph
Write a paragraph explaining how you can see Newton's 3 Laws of Motion in that sport (just one sport for all three). Re-write the laws in your own words, and include an example of how that law can be seen in your choice of sport. The Law of Conservation of Momentum does NOT need to be included.
1) On one side of your paper, make 3 columns, one for each law.Jot down briefly how you see that law in your sport. (These are like your "notes," a way to help you write your paragraph...)
2) On the other side of the paper, use your notes to write a paragraph. You should tell me what the law is, and how you see it in your sport. You should have a minimum of 5 sentences.
Grading:
* Is a paragraph, at least half a page long with five sentences
* All 3 Laws included and paraphrased (not including the Law of Conservation of Momentum)
* 3 correct sport examples, one per Law

Newton's Laws Seen one of these in action before? It's called Newton's Cradle, because it obeys Newton's Law of Conservation of Momentum: Use this link to try it for yourself (you'll have to scroll about half-way down the page to get to the flash animation).
