The marble roller coaster is an energetic fun experiment a lot of people will like. slow and clanking, the string of cars is pulled up to the crest of the tallest point of the roller coaster it goes after the loop the loop but before it hits it realizes it needs to figure what kind of speed the marble needs to make the loop.

Roller coasters can be very different, but they usually follow the same basic track to make the ride more thrilling.The ride starts when the chain pulls the cars up the first hill. The first hill is the tallest, so the potential energy is at its most at the

to review what they can and cannot do. In normal braking, a vehicle slows as its wheels are

The cars on a typical roller coaster are not self-powered. A standard full circuit coaster is pulled up with a chain or cable along the lift hill to the first peak of the coaster track. The potential energy accumulated by the rise in height is transferred to kinetic energy as the cars race down the first downward slope. Kinetic energy is then converted back into potential energy as the train moves up again to the second peak. This hill is necessarily lower, as some mechanical energy is lost to friction. Not all rides feature a lift hill, however. The train may be set into motion by

ground, so it accelerates. If the track tilts up, gravity applies a downward force on the back of the

What do you think about when you're on a roller coaster? Do you ever think how you're being pulled up this huge hill or down the hill?

Next, the independent variable was the sail car and shed car. The speed acceleration was the dependent variable. The constants marble distance of photogate the angel of the track.

When the mousetrap car moves down the track, the speed of the mousetrap car decreases, therefore my hypothesis was supported. At 1 second, the mousetrap car was traveling at a speed of 3.2 m/s. At 2 seconds, the mousetrap car was traveling at a speed of 2.35 m/s. At 3 seconds, the mousetrap car was traveling at a speed of 1.53 m/s. At 4 seconds, the mousetrap car was moving at a speed of 1.2 m/s. At 5 seconds, the mousetrap car was traveling at a speed of .98m/s. “A car will eventually come to a stop if just allowed to roll as the friction between the road surface and the wheels causes friction that causes the vehicle to stop,”(Examples of Rolling Friction). The evidence supports the claim because the wheels of the mousetrap car are moving

A roller coaster’s popularity depends mainly on many different basic elements which are parts that are usually on roller coasters such as the headchopper, the launch track, and the lift hill. The headchopper is any place where the roller coaster overlaps itself or appears to come very close to the passenger’s heads. The launch track is a part of the coaster where the train is accelerated to its max speed within a few seconds and drastically increases the train’s kinetic energy. The lift hill is similar to the launch track by increasing the train’s potential energy by raising it to the roller coaster’s

Lights, cameras, action! This new coaster is gonna have everyone running towards the entrance! There is a new coaster coming to town called the Hollywood Coaster of Fame! Hollywood Coaster of Fame is a coaster based on the bright lights and stardom of Hollywood. Riders will experience a speed from 0-75 miles per hour which will shoot the riders up a 195-foot hill. Before dropping down the hill the riders will feel a bit of suspense on the very top of the hill, which is where the potential energy is the highest. Then riders will feel the weightlessness of dropping down the 195-foot hill into the first loop where gravity pushes down into their seats. The momentum of the loop will take them around a sharp turn making

While you are going up the first hill you will be traveling at a constant speed of 8 miles per hour. The machine in the roller coaster has to use a certain amount of work to get the mass of the people and cart up the first hill. Right before you start to spin down the first hill there will be gravity and acceleration pulling you down the spinning hill. Once you stop spinning while going down that first hill you will be at a spot right before the first hill where you will be experiencing terminal velocity. After you finish that loop you are gonna get pushed right up another hill and as you are falling down the hill you are gonna loop forward and be weightless while going through newton's 2nd law as you near the bottom of the hill. You will start going up another hill like the one on Track A and twist down in a corkscrew type way. During the twists you will experience very much centripetal force. You will go around another little turn like you did on Track A then instantaneous speed will be slowing you down right before you go back into the station.

On the other hand, potential energy is defined as energy of position or stored energy. The roller coaster utilizes potential energy, which is dependent of the mass of the train and the height, when the motor lifts it up the hill and then, this transfers to kinetic energy when the roller coaster suddenly drops, gaining speed. Therefore, the sum of kinetic and potential energy forms the mechanical energy of the roller coaster, energy which is occasionally lost throughout the ride due to friction. Potential energy is transferred into kinetic energy at the beginning of the ride as the roller coaster undergoes its first descent. When the train of the roller coaster is at the peak of the hill, it possesses a lot of potential energy and much less kinetic energy because it is at a high altitude and moves slowly. Conversely, when it is at the bottom, it has a lot

Near the top of the ramp, the car’s speed was around 102 centimeters per second. In the middle of the ramp, the car’s speed was around 156 centimeters per second and near the end of the ramp, the car’s speed was around 196 centimeters per second. No one in the group pushed the car at any time. The slope of the ramp was also constant the entire time. There had to be an explanation for why the car’s speed was faster as the car went on. What we came up with was that as the car traveled down the ramp, it picked up speed. Once we plotted these points on the graph, it was extremely evident that this was in fact what had happened. The graph clearly showed that the speed of the car was increasing as it went down the
