    Physics plays an important role in the mechanics of a roller coaster. The thrilling ride cannot be appreciated, if the physics of a roller coaster is not understood. The loops, bends and hills are all affected by physics. The first hill of a roller coaster is the initial start of energy. Potential energy begins the transfer of energy on the first hill. A chain motor pulls the cars to the top of the hill creating potential energy. Potential energy being defined as the energy determined by its position compared to that of its surroundings. The potential energy is built up due to the height of the roller coaster. Although some of the energy is lost it is eventually turned into kinetic energy. Kinetic energy also referred to as motion energy is…

    My Slapshot In Hockey

    • 285 Words
    • 2 Pages

    Last Thursday, I had a hockey practice, and before anyone else came on the ice, my brother Michael and I were just shooting around. To see how fast my slapshot is, I had him stand at the other end of the ice, and using his phone, see how long it took for my shot to go from one goal line to the other, exactly 60.96 meters. Keeping the puck on the ice the whole time during my shot, changing just the position of the puck, my slapshot took 4 seconds to cross the far goal line, making my slapshot…

    Essay On Kinetic Friction

    • 612 Words
    • 3 Pages

    Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is…

    Essay On Roller Coasters

    • 2610 Words
    • 11 Pages

    Friction plays a major role in actual roller coaster physics. Once cars are lifted to the top of the hill, gravity takes over, and kinetic energy is transferred throughout the remainder of the ride. Mechanical energy is not consistent. Mechanical energy is the sum of potential energy and kinetic energy. Mechanical energy can either be potential or kinetic. The four types of friction are static, sliding, rolling, and fluid. The normal force is one component of the contact force between two…

    Mouse Killing Car Project While building and testing a mousetrap car the builder must understand a few simple but, vital mechanics. The vehicle will be propelled by the pulling force of a small mousetrap. The end goal of building this car is to have it go from one end of the room to the other on top of carpet. Leverage, kinetic energy, and friction; are things to take into consideration while testing and building the car. There are two types of levers to keep in mind. The first is the lever arm…

    Purpose The purpose of the lab is to design an experiment to verify the spring constant for an unknown spring, also known as k, how much a spring resists change (compression or expansion). We used a method changing a mass and measured the change in x.

    Marching Band Physics

    • 625 Words
    • 3 Pages

    Final Draft Marching band is a group of musicians who play instruments while marching together. Either to make shapes and pictures. Usually at some sports events and parades and are performed competitively as well. The Blue Devils are a well known, professional, marching band. Nevertheless there is a lot of physics involved. Whether it’s the tempo of the song, this would involve speed, other things are in factor too like velocity, acceleration, friction, and momentum. Mostly in the movement.…

    Final Momentum

    • 337 Words
    • 2 Pages

    Using the data obtained through the Labquest2 computer system, my group and I calculated exactly the initial momentum and kinetic energy, final momentum and kinetic energy, and percent of momentum and kinetic energy that was lost through these collisions. To calculate momentum we used the equation p_i=p_f which expands to m_1 v_1i+m_2 v_2i=m_1 v_1f+m_2 v_2f. We can say that our first hypothesis was accepted since in collisions 1 and 2 the total initial and final momentum was similar values.…

    Rube Goldberg Project For this Rube Goldberg project I am going to explain how my machine worked. My simple task was to pop a balloon. The item we used to pop the balloon was a mousetrap. I am going to go step by step through how I created my Rube Goldberg machine. First, we started out with a ramp that we dropped the ball on. That was our potential energy. Next, we had a ball drop down a tub at approximately 180°. That was mechanical energy. After that, the ball went through an elbow and…

    https://www.youtube.com/watch?v=NcmF5lDL8MM 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…
