NLGP 2
­ Stopwatch
­ Golf Club or Broom
­ Cones
­ Bowling Ball
­ Basketball
Hypothesis: I believe that ​the force I apply ​will affect how a bowling ball moves.
Prior Information: Newton’s First Law is stated as:
unbalanced force. _
An object at rest will remain at rest until acted upon by an Inertia is defined as: ​The resistance and object has to change. _
Procedure: circled 1. Set up the course in the hallway, as seen above. Use cones for the route markers in the hallway. The starting zone will be a square of cones. The large obstacle at the end will be a garbage can that must be before returning to start. 2. When the timer says “Go”, complete the course as quickly as possible. Be careful of obstacles (classmates, doorways, walls, etc.) and keep quiet in the hall. 3. You must stop the ball completely in the “Start/Stop” Zone for time to be stopped. 4. There are 10 second penalties for the following infractions: a. Hitting the ball in the “no touch zone” b. Disrupting other classes c. Contacting ball with anything besides the club (including cones) d. Starting before “Go” is called Data: Time to complete course (sec) Number of penalties 1.

It's effective to move slowly through the course the first time, to get​ ​a feel and strategize. The second time through pick up the pace.
Questions: Answer the following questions using terms such as “​Force​”, “​Inertia​” and “​Newton’s 1st ​
Law​”. 1. How do you get the ball to speed up? _I applied an opposite force to the ball with the golf club.
2. What makes the ball slow down? By placing the club infant of the ball, another instance of opposite force._ What makes the ball turn or change direction?
3. Describe the speed and motion of the ball in the “no touch” zone. What does this say about Newton’s First Law? _ The ball because of my force I applied sped up and moved somewhat in the direction I had applied the force to, then it began to slow down a bit for me to catch up._
4. If you don't begin slowing the ball soon enough for a turn, describe the path the ball "wants" to take using ​words ​and a ​picture​. How does this relate to Newton’s 1​st ​Law? It will most likely crash into something or go through the target point.
6.
What is something you could do to improve upon your time? Would you prefer to use something other than a golf club? If so, what would you use? I will hold my hand closer to the ball (further down on the club) to insure the most control over the ball, also I will move a bit faster.
7.
If you were given the chance to retry the course, do you think it would be better to take your time and avoid penalties, or go as fast as possible? Why? Go fast! I already know what the course is like and the best strategy.

ROUND 2 – Let’s Make Some Changes! Purpose: ​To see how wait and mass effect Newton's Law of Motion. Materials: ​_Broom Stick ­Cones ­Bowling Ball ­Basketball Hypothesis: ​The lighter the basket ball the easier it maneuver. Also the more surface area of the broom will contribute to the control.

27 1 22. Average: Additional Observations: Questions:
Answer the following questions using terms such as “​Force​”, “​Inertia​” and “​Newton’s 1st ​ ​Law​”. 1. What was the difference between the two objects that were moved through the course? ​_
It was much easier to move the basketball because it had a much lighter mass. 2. What was the difference between the two objects used to move the ball or floating disk through the course? ​_
The mass and surface area of these objects are different. 3. Which day was it easier to complete the course? Why? ​_
Day 2 because they basketball was lighter and easier to move. 4. Describe the speed and motion of the two projectiles through the “no touch” zone. What does this say about Newton’s First Law? Does this law apply to all objects? ​_
The bowling bowl had more inertia so it seemed to resist friction more than the basketball. This made it move through the no touch zone without slowing down as much. 5. If you were to make any other variations to this lab what would they be? Why would you make these adjustments? More obstacles, only because it's very easy to navigate already. Or maybe changing speeds in different areas. 6. If you were given the chance to retry the course, do you think it would be better to take your time and avoid penalties, or go as fast as possible? Why? Go as fast as I can and try to beat Jared. 7. If you used the same amount of Force to move the bowling ball, as you did the flying disk which would move faster? Does this help you make any conclusions about a relationship between ​Force​, ​Mass​, and ​Acceleration​? They would eventually move with the same speed, because although the masses are different the force is the same. At first the disk would be faster but if it stays that speed the bowling ball with catch up.
