Physics of Skiing Science research paper Johanna Kelly For my science fair project, the topic I wanted to study were the physics of skiing. The question I’m going to do for my experiment is, does wax affect the speed of skiing? I’m also planning on testing the wax in different conditions, and at different slope angles. This seems like a very interesting project, because I really like skiing and snowboarding. Last year my project wasn’t very interesting to me, so I’m glad I picked a…

entire body to develop a mechanical advantage. For pushing, pulling or wielding a heavy object or tool, a Master of Science Thesis Jijju Thomas 2 Introduction stable stance is found with all the points of contact considered. When producing a pushing force, a human’s stance often consists of either one foot or both feet displaced some distance from the object being pushed. The two stances are called the ‘feet-apart’ pose and the ‘feet- together’ pose as shown in Figure 1-1. An angled-body…

conservation of mass in part 5 of the experiment, dissolving sugar in water. The law of conservation mass states that matter cannot be created or destroyed by can enter or leave the system. The system’s change in mass was 0.00 grams, resulting in support of this statement. The balance had an uncertainty of 0.05 grams. b. With this experiment, we had a closed environment within the vial, not allowing any particles to come in or out, further explaining why there was no change in mass. The…

Have you ever been to an amusement park and wondered how a rollercoaster goes around the loop of the track? Well I sure have, this is all due to centripetal force. This is a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. The curves of these loops on rollercoasters resemble the curves of a circle. The coaster is continuously changing its direction while moving through the loop. This change in direction is…

acceleration of a cart both with and without added mass. In a sense we will be seeking to confirm Newton's second law of motion. As stated in the second law of motion, force is equal to mass multiplied by the acceleration or F=ma. When we increase the mass we would expect the acceleration to decrease when force is the same as the rewritten equation would be f/m=a. In this case it is important to specify the difference between mass and weight. Scientifically mass is the amount of matter in a…

Personal Write Up The whole point of this project was to build something that the class could apply their knowledge on the things Mr.Kunz has taught us these past couple units. Along with being able to apply their knowledge, teams had to be able to build a decent mousetrap car to get the best grade possible. In order to get a car to go the maximum distance Taylor and Daniel came up with three different main variables: lever arm length; to see how much leverage gets the car the farthest, car…

Method Measure the mass of the cart and hanger and convert grams into kilograms Set up the cart on the track and attach it to the string and weighted hanger placed on the pulley system Set up the Vernier motion detector under the hanger to appropriately measure its acceleration…

This investigation focusses on an egg falling off a height of 4 metres in the fastest possible time without breaking the egg. In order to make this happen, an investigation must be conducted on the forces acting upon gravity, crumple zone theory, and energy transfer and absorption. The world is made up of matter and energy (Cool Cosmos, 2015). Matter is made up of atoms and molecules and these atoms and molecules are always in constant motion because of energy (Cool Cosmos, 2015). Gravity is…

that outside force acts upon them. That force is known as none other than gravity (-9.8 m/s2 ). Newton’s Second Law fits very close to the first law. It tells us that mass and acceleration are directly proportional in regards to force. This is known as the formula, F=(m)(a), which is force equals mass times acceleration. The more mass and acceleration a gymnast has when running at the vault, the greater the force produced on the vault. A gymnast must reach a maximum velocity on their approach…

a. The child’s first goal in her original task of creating a machine to make spaghetti is to put a pole in the hole of one box and put the other side of the pole into the hole of another box, so they are connected. She observes that the pole will not go through the hole in the box. She then takes off the ribbed cylinders on each side pole, and slides the boxes with holes in them back down the poles. Her goal is still trying to place a pole in the side hole of one cube to connect it to the cube…
