The instability of the roller coaster creates a spring constant. This means that as the car travels through the roller coaster, it loses energy because the track shakes and moves. For example, when viewing the videos it became apparent that when the car entered the loop, the track shook violently making it difficult to determine when the car reached each location. As the car went through the track, going up into the loops it grew in height, decreasing in kinetic energy while increasing in…

Moment of Inertia for Rotating Objects Lab Report For this lab, the guiding question that needed to be answered was: For the system shown below, is there a functional relationship between the rotational inertia of the rotating object and the time required for the hanging mass to fall a known distance that can be determined experimentally? (as seen in Figure 1) Before beginning to attempt to answer the question, the lab had to be set up correctly. First, the rotating object was set tangent to…

Over the past 5 weeks I have taught myself to play and practice golf to a decent capability. I have done this by researching the skills and techniques on how to drive a rubber golf ball 60 to 100m, which I have achieved. I have applied knowledge from biomechanics, anatomy and sport psychology. A big part of helping me to achieve this unit was the the goal setting and visualisation aspect of sport physiology. This helped me from the start to see what I wanted to achieve as I strived to reach my…

According to the Figure 1 and the chart above, it clearly shows that the time it takes the object to hit ground did being impacted by the surface area and mass. The greater the mass, the more time it takes the object to hit the ground. While the larger the surface area, the faster it hit the ground. Because of the air resistance, larger surface area caused the object to fell faster than the object with smaller surface area. Although the background research proved that the mass doesn’t affect…

I read an article about tennis stances that was written by a tennis couch in Japan. He strongly stated that the player who used proper tennis stance could control the game. For example, Rafael Nadal and Lleyton Hewitt are pro tennis players who are especially good at using footwork in a game. They use appropriate stances when they return the ball, so they seem to run very fast and can cover wide range of the court. In the article, he introduced four kinds of stances and when should we use.…

In particular a pitcher. This is because out of all the positions on a baseball team they generate the most speed and power from their throws. I also chose baseball pitchers as my ideal athlete because the mechanics of pitching a baseball is one of the most researched and documented motor skills in sports. Slide Five The ideal technique. As you can see from the picture the ideal technique that I found is from a skeleton. The two key things that make it the ideal…

Makayla is talking to Mia about the whether we ever landed on the Moon. Mia says,” I have a theory about that.” Using 3 – 4 complete sentences, what is wrong with Mia’s use of the term “theory” in this instance? Mia is wrong to use the word theory because the word implies that you have some scientific evidence to back up whatever your theory states. She is implying that she went through an experiment and gathered information about her theory. She should gather evidence to use the word…

As mentioned before, pitching requires several joints and muscles. Shoulder and elbow are two of the joints that are involved in the movement. Of the six phases of pitching, arm cocking, acceleration and deceleration are the three phases when elbow and shoulder joints experience high magnitudes of forces (Oyama 83). Windup is the phase that occurs when the pitcher places the non-throwing hand is in front of the target. In the beginning of the arm cocking phase, the non-throwing shoulder is…

Propulsion is a force that pushes forward or drives and object forward. This concept can be seen in action with the use of a balloon powered car; this car demonstrates a type of propulsion system in which it produces thrust and potential energy and uses the kinetic energy that it will gain from the movement to push the car forward. The thrust is obtained from the balloon which applies Newton’s third of motion that states, “for every action, there is an equal and opposite reaction.” Specifically,…

The Physics of Cheerleading The sport I chose to do my essay on was cheerleading, because of the physics shown all throughout the sport. There are stunts, tumbling, and jumps. Cheerleading is a sport that involves all these tasks and much more. Cheerleading consists of many concepts of physics, such as Gravity, Newton Laws of Motion, momentum, torque, potential and kinetic energy, velocity, force, gravitational acceleration, free fall. I will explain the definitions of each concept, so readers…
