Inertia

Candy Land is a brand new, hydraulic steel roller coaster ride, using an abundant amount of modern technology, recently added to Hershey Park. Loops, a corkscrew around some delicious ice cream, and a 100 foot drop are all included in the ride. Not only is there scrumptious looking scenery, but also the roller coaster has an average speed of 60 miles per hour, and can reach speeds up to 85 miles per hour. If friction and gravity were not present during the ride all of the passengers would go…

This experiment was done to see what variables (weight, wind, friction etc.) affected the apogee of the rocket. The class did this by recording everyone's rocket weight and compared them to the apogee's after they had been launched. Due to different variables, the apogee might be affected in a variety of ways, one being the weather. After the class found all of the data, it was compared and analyzed for any patterns. The rocket had different forces acting upon it during the flight stages. The…

The scientific community throughout history and the scientific revolution have been focused on the legitimacy of scientific claims, as new advancements constantly change the way the scientists observe and understand principles. That which may have been true in the past could change to a false concept. Rossi explains this through Thomas Edison and his development of the light bulb. “Until the nineteenth-century invention of the light bulb it was an accepted truth that illumination was produced by…

• Wheel Diameter is taken as 26 inch (0.6604 meter) so radius of the wheel is taken as 0.33 meter.(5) • Drag co efficient is taken as 0.9 from book High-Tech Cycling by Ed Burke.(6) • Wheel Inertia is calculated by assuming the mass of the E-Bike tire which is 1.2 Kg and radius is 0.33 meter so the inertia of the wheel becomes 0.13068 and for two wheels it is taken as 0.2613 Kg.m^2. • Motor torque, Brake torque, Gear Torque values are taken my team mates who are designing Motor, Brake, Gear.…

in mind. The first is the lever arm that is pulling the string wrapped around the axle and is attached to the mousetrap. When choosing a length to have the lever arm the equation to find torque which is force*lever arm. Torque is then used to find inertia which is then used to calculate…

Breaks are not something people take the time to think about. Even if they are fundamental to the vehicles many people use every day. The functionality of breaks is contributed to physics and engineers ability to understand that physics. There is a lot going on when people press on the brake pedal in their car. The most basic principle of brake pads is in fact friction. This friction is the thing that transfers the energy of the car moving forward to heat energy. Brakes also use pressure as a…

Isaac Newton’s Laws of Motion and Crumple Zones Crumple Zones design and function The crumple zone is the front and the rear of a motor vehicle that is designed to crumple without difficulty and to absorb the force of the impact in a crash. Crumple zones are also known as crush zones and they absorb energy in a crash so that it doesn’t transmit to the occupants as much. The zones are now made in cars to prevent death for occupants or serious injuries when in a crash. The front of the vehicle…

deep within our nation’s history and still clouds the minds of those in present day. Inequality affects day to day interactions. Inequality barrages job opportunities. Inequality cloaks chances for education. Ultimately, racial inequality acts as an inertia for change and development as a society. Whether it be the statistics on incarceration, the ethnic distribution within communities or even the diversity within workplaces, there are countless examples…

exiting. although acceleration is also important for that fast, scary feel in general speed is more important. First of all doing corkscrews or going upside down you need to be going fast so that it is safe. This works by using centrifugal force or inertia. If it is too slow you wouldn’t be able to do it of have to need very heavy buckling for safety and, that wouldn’t be fun. Also I think that the main thrill factor in a ride is speed, when you take that away stuff that was fun becomes boring…

‘Push it to the edge’ (or on the edge (of the skateboard)) -Cesar Castro I used to hate people who rode those silly planks on wheels. However, as an attempt to learn something new and foreign I decided to meticulously study the dynamics between science and skateboarding (soon to be my second favorite thing). While doing my preliminary research (finding a skate shop, buying equipment, and finding skate spots) I learned that almost every aspect of skateboarding is scrutinized to the point where…
