Factors Determining the Stopping Distance of Rollers Down a Ramp
Theory-
-------
When the roller is rolling down the slope then potential energy is
converted to kinetic energy that converts into heat energy.
MGH = ½MVsquared
The loss of kinetic energy on the carpet is ….
½MVsquared = braking force x braking distance
therefore….
½Mvsquared = F x
so MGH = F x

This relation ship can be tested for a fixed angle, roller mass and
fixed carpet.
Predictions-
In this experiment, before it was conducted and results were obtained
, I predicted that for all the rollers, that the stopping distance
would be directly proportional to the distance up the ramp. This
prediction can be tested by plotting a graph of the results.
Variables and Constants in the Experiment

Variables
Constants
Distance up ramp
Type of carpet
Distance along carpet
Angle 'G'
Mass of roller

To maintain a fair test these are the procedures I had -
· 1 fixed angle
· 1 set of rollers
· to make sure that the ruler was at the bottom of the ramp
· A fixed interval (3,6,9ect….)
To find out if my predictions were correct, I conducted an experiment.
It was set up as follows;

Ever wondered how roller coasters work? It’s not with an engine! Roller coasters rely on a motorized chain and a series of phenomena to keep them going. Phenomena are situations or facts that have been observed and proven to exist. A few types of phenomena that help rollercoasters are gravity, kinetic and potential energy, and inertia. Gravity pulls roller coasters along the track as they’re going downhill. Potential and kinetic energy help rollercoasters to ascend hills and gain enough momentum to descend them and finish the track. Inertia keeps passengers pressed towards the outside of a loop-the-loop and in their seat. Gravity, potential and kinetic energy, and inertia are three types of phenomena that can be observed by watching roller

Investigation of the Relationship Between Mass of a Vehicle and Its Stopping Distance Problem The problem to be investigated is "how does the mass of a vehicle affect its stopping distance when brakes are applied?" This problem is related to the conservation of energy and will be investigated through a trolley going down a ramp. A simple trolley will be used to represent the vehicle and weights attached to the rear of the trolley via a pulley system will act as the brakes. Throughout the experiment energy will be transferred into many forms but no energy will be lost or gained. As the trolley is raised it gains potential energy, when released down the ramp this energy is converted to kinetic energy.
Roller skating is said to have been born during the summer months when ice was not available. The first documented inventor of roller skates was John Joseph Merlin who was born September 17, 1735, in the city of Huys, Belgium. Merlin was well known for his abilities for making musical instruments and other interesting mechanical gadgets. Through various incarnations, roller skates strove to replicate the streamlined speed and maneuverability of ice skates, but without ball bearings or shock-absorbent wheels it would take 200 years before that dream was achieved. Even as late as 1960, the Chicago Skate Company attempted to market an inline skate that looked much like today's skate, but it did not offer sufficient comfort, stability or a reliable brake (Zaidman 1). Although the Chicago Skate Company’s attempt of the inline skate was not successful, it did play a pivotal role in the molding of what is now known as inline skating.
the length of the slope can be used to calculate the speed of the car
The convoy consisted of thirteen vehicles; 6 M-ATV’s and 7 Mine-Resistant Ambush Protected (MRAP) vehicles. The lead MRAP’s was configured with a Mine-Roller, an attachment on the front of the vehicle used to combat pressure plate Improvised Explosive Devices (IED). Lead vehicles within all patrols were outfitted with Mine-Rollers and proved to be extremely effective in combating pressure plate IED’s. I always knew that Mine-Rollers were essential in convoy operations but it never occurred to me until the morning of August 3, 2014 how much they changed the convoy’s ability to maneuver safely in enemy terrain.
The most noticeable concept of physics presented in the video is projectiles. The skiers start at the top of a ramp and then they slide down. They leave the ramp at an upward angle and take a projectile path that goes up and then down. The physics is clearly not broken because the skier is experiencing a constant acceleration in the vertical component, which is gravity. As the skier is on the ascent of the projectile path, gravity is working against and is negative. As the skier is on the descent of the projectile path, gravity works with the skier and is positive. In the horizontal component, the skier does not experience acceleration, but instead experiences a constant

A roller coaster is a thrill ride found in amusement and theme parks. Their history dates back to the 16th century. It all started in Russia, with long, steep wooden slides covered in ice. The idea then traveled to France. Since the warmer climate melted the ice, waxed slides were created instead, eventually adding wheels to the system. The first roller coaster in which the train was attached to the track was in France in 1817, the Russess a Belleville. The first attempt at a loop-the loop was also made in France in the 1850s. It was called the Centrifuge Railway. However, government officials quickly diminished the idea when the first accident occurred. Inventors since then have continued to capitalize on people’s love of a great thrill, always trying to make them bigger, faster and scarier!
Wheeled Coach is the world’s largest ambulance manufacturer. With multiple different products and around 3000 different raw materials there is huge potential for operating failures. In 1994 Wheeled Coach implemented a new MRP system called MAPICS. They hoped that by doing this that they would gain better control of their excess inventory that was becoming overwhelming.
