Physics was observed during a DHS girls lacrosse game by Newton’s Laws and in free-fall. Newton’s Laws consist of 3 different laws, the law of inertia, F=ma, and action-reaction forces. Free-fall was observed in the game when the lacrosse ball falls, and only gravity acts upon it. All in all, Newton’s Laws and free-fall was portrayed during the lacrosse game.
In this project, David and Goliath, assigned by Mr. Kumz, a catapult was built, Springy.. In this experiment three different variables were tested; angle of launch, stretch length, and the skittle position. The angle of the launch had three measurements: zero and forty-five degrees. The stretch length measurement were 2, 3, 4, 5, 6, 7, and 8 centimeters, while the skittle position was flat and on its side. Springy’s most effective launch was at a zero degree and with a stretch length of five centimeters.
The parts of a trebuchet, work with Newton’s first three laws; to state simply, anything at rest stays at rest while anything in motion stays in motion unless something acts upon them. This law is used as gravity causes the counterweight to free fall, the momentum of this object builds up potential energy as the arm rotates around the fulcrum. Then, Newton’s Third law as the counterweight falls, the sling (on the other end of the beam) rotates up, then the potential energy is turned into kinetic energy as the projectile is released from the sling and
The golf ball would fly down a race track and then set off another mousetrap. Next, the mousetrap would pull a string out of a book which would close the book on top of scissors. Finally, the scissors would cut a string which is holding up a dumbbell and the dumbbell would crack the egg which is sitting in a bowl. This is the project we decided to design in order to crack our egg.
For this experiment, I used the online Mass & Springs PhET simulator to perform the experiment. First, I positioned the ruler so that 0 was on the line at which the end of the spring was at rest. Then, I put a 50g weight on the end of the spring and let the spring come to rest. After that, I pulled the spring down 10cm and released. I recorded the point at which the spring’s rebound stopped.
In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
The hypothesis of the badminton birdie experiment was accepted. When a little mass is added to a badminton birdie, and hardly any weight, the number of times it goes over the net, when you hit, it will increase. The Sportime and Referee badminton birdie brands were the two different brands used in this experiment. When mass was not added to the badminton birdie, the graph shows the Referee brand has more hits. The Referee brand was still in the lead at two grams added, but at 4 grams the brands were tied.
Could you imagine what it would be like if you go to your little cousin’s birthday party, and he or she get upset because there were no balloons? If legislators ban balloons, this imagination could become reality. There is a controversial topic going around that asks if it would be best if balloons were banned in the United States. This controversy was discussed in a video, “California Aims to Ban Metallic Balloons to Reduce Power Outages,” the editorial, “Parties Can Be Fun Without Balloons,” by Natalie Romero, and the other editorial, “Balloons Bring Joy to Millions,” by Theo Lewis. While there were similarities among the sources, there were also many differences as well.
CHAPTER: (1) Introduction 1.1 Problem Summary and Introduction: The goal for our group is to design a ping pong ball launcher. The launcher needs to be scheduled to launch one solo ping pong ball one at a time over a set obstacle and into a bucket of a chosen diameter. The determination is for the launcher to have the capability to launch five ping pong balls one at a time into the container within one minute, having none of the ping pong balls bounce out or miss the bucket. The launcher can be made out of any matter preferred and can launch the ping pong ball in any anticipated way, except by explosion.
Omar Fahmy Ms. Mao Physics 02/23/15 Physics Behind the “Pill” Research Question: How do the physics of a rugby ball suit the specific needs and characteristics of the game? Picture: General Information: Rugby, a sport not known to many, and mainly prevalent in the southern hemisphere, is a game known for its teamwork, cooperation, agility, and violence.
I taped the back of two plates together which is a wheel of the car, and used sticks to connect all four wheels, then I putted the balloon to the car and start our first trying. Surprisingly, the car didn’t move at all! Why, it is not as well as I thought. I failed in the first trying. I told myself, “One fail will not prove anything, I can do it”.
SIR ISAAC NEWTON 1 Sir Isaac Newton Jaqueline Martinez Algebra II PSJA North Early College High School SIR ISAAC NEWTON 2 The name Isaac Newton may sound familiar to you and if it does not then you surely must be living under a rock. He is known because of the concepts he has contributed in both science and math, many of which will be mentioned in this paper.
The next 20 arrows were similar: my shots landed reasonably well into the huge targets, but I would need a lot more practice before the arrows landed in the bulls-eyes with any sort of regularity. After 5 such target sessions, I took a moment to dash around in the gimbal elliptical machine for ten minutes, then returned to the target field for accuracy training, taking 6 seconds on each arrow rather than the three I spent on each arrow earlier. The arrows still landed away from the bullseyes with frustrating regularity, but it was an improvement over 6 months ago, when I couldn't hit the target
As soon as I got the ball, I started to race down the court pounding the ball as I was dribbling. I squared up facing the hoop getting ready to take my shot. I raised my arm up, releasing the ball with my fingertip with poor form and arc. The ball went flying towards the hoop very fast. The sound of the net went swoosh
Beginners may have a hard time hitting their target accurately, but this comes with time and patience. Just remember, “when firing the shot, check the sight alignment and then fire” (Quandahl 11). The approach to become proficient with a gun is just practice, practice,
