Science friction What will happen In this information report, you will be consistently provided information about friction and other forces, our aim is to find out with friction does and acts upon by using a toy car and a ramp. We are hoping our investigation will provide information about things we could Improve to make the car cover more distance including the weight of the car, the stand, the inclined plane and the environment. We also hope it answers how much speed the car can produce and how far it can go. My hypothesis is the higher we put the ramp the more forces will act upon the car giving less friction meaning the car will accelerate more traveling to a further distance. Friction Friction
She explains it’s because scientist are able to receive more accurate data from them. By this the scientist were able to innovate the car’s structure to improve safety in newer models.
Also, the equations for Potential energy and Kinetic energy are stated to get the Total Energy. They are respectively:
the load , the height of the ramp or the angle. I have chosen the

Rolling a Car down a Ramp Investigation PLANNING When planning my experiment, I will need to take into consideration. the following points: -Fair testing -Equipment -How many results will I get? -What range of variables I will experiment with I will be investigating, by varying the height of the summit of the ramp. is raised off the ground, if the average speed increases or decreases.
friction, affecting the speed and distance the ball rolls. Title: The Effects of Height, Length, Surface, Weight, Size, and Material on the Distance a Ball Rolls Down a Ramp Aim: The aim of this experiment is to investigate the factors that affect the distance a ball rolls when released from the top of a ramp. Variables:
be the height of the ramp which in turn would affect the angle of the
“How about we use a pulley system with a weight at the end to push the car forward?” my team member suggested. “Or we could use a hammer launcher,” I proposed. We went back and forth, contemplating different methods. We faced trials, tribulations, and troubles in the design process. Building and perfecting our designs took weeks, but our coach guided us throughout the process and encouraged us to “Never give up!” We researched the effects of different factors that could potentially come in the way of our success and analyzed all of the device possibilities. Even when research got arduous and we couldn’t agree on something, we never gave up on our dream of placing in the regional competition. This was one of the hardest challenges I’ve ever faced in my Science Olympiad career, but our unfaltering dedication and our belief in success helped us persist in the face of setbacks. Once we finished our plan, we began to build the device. It was exhilarating to see our plan come to
“Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).” Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included.

The golf cart truly is a work of art as it is addressed in the paper. There is now an initial concept in the development of the modern day golf carts, the importance of the development of Harley-Davidson on the modern day golf cart, and the basic comprehension of the gas and electric engines involved in the process of making the modern golf cart. The design of the modern day golf cart has changed immensely since its introduction seventy years ago. “He who has the fastest golf cart never has a bad lie.” –Mickey Mantle
I have learned quite a lot while constructing my mousetrap car. For example i learned that the friction that is active while the mousetrap car is in motion is rolling and static. Rolling friction occurs when an object rolls over a surface, in my case the CDs are rolling on the floor causing the car to move. Static friction occurs when one solid surface slides over another, for example my solid car sliding over a solid surface.Fortunately i didn't have very much problems related to friction.
This paper is a look at the physics behind car racing. We look look at how we can use physics to select tires, how physics can help predict how much traction we will have, how physics helps modern cars get there extreme speed, how physics lets us predict the power of an engine, and how physics can even help the driver find the quickest way around the track.
What type of ski wax will reduce the friction between ski bases and snow the best: rub on, paste, spray on, or hot. Skis slide because when pressure is applied to the snow it creates a thin layer of water in between the ski bases and the snow. Furthermore, skis repel water causing them to slide instead of sticking to the snow. If ski wax is applied by rubbing, pasting, spraying, melting, then melt on wax will reduce the most friction because it coats the skis more evenly, fills in small imperfections and provides a thicker protective barrier.
Fraction Friction is the title of this series of lesson designed for year seven students. It will build on previous basic knowledge of fractions and consider more advanced thinking including algebraic thinking and computation. Fractions have always represented considerable challenges for students and a lack of understanding is then translated into difficulties with fraction computation, decimals and percentage concepts and the use of fractions in other areas especially algebra. (NMP, 2008) as cited in Van De Walle, Karp & Bay-Williams 2010. These lessons are designed to further enhance students understanding of fractions and how they can be compared and adjusted to use in mathematical practice. The students will have the opportunity
