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…

In this world all of us have different views on activities, food, and a number more. There are various activities, like snow sports. When choosing a snow sport, a person needs to know the difference between snowboarding and skiing. First, a person needs to know the difference in the learning curve involved in snowboarding and skiing. Skiing is probably the harder one to master. In skiing, a person can clock at least 80 miles an hour on a head wall(this is the steep face of a hill; also it is a…

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…

We can easily convert this into Cartesian form by replacing z by x+iy |(x+iy)-(-3 +2i)|=5 |(x+3) + i(y-2)|=5 √(〖(x+3)〗^2+〖(y-2)〗^2 ) =5 or 〖(x+3)〗^2+〖(y-2)〗^2=25 Which is the exact form of a Cartesian equation of a circle with a center of (-3, 2) and a radius of 5 We could check if a particular point lies on the circle Ex. z2=1-3i Substituting into the equation of the circle, with z replaced by z2=1-3i |(1-3i) - (-3 + 2i)|=5 |4-5i|=5 √(4^2+〖(-5)〗^2 ) =5 41=5, which is not true, thus z2 does not…

Summation of forces is the use of the right muscles in the correct order to get the best most efficient result. This is achieved by using big muscles before small muscles, from the initial start of the swing too the follow through phase at the end. This was applied…

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…

things that make it the ideal technique in my opinion is in the second phase it has a nice wide base stride and its center of gravity is nice and low. The second thing is in the third phase. As you can see the skeleton has created a lot of elastic force at its elbow joint. This is where the main source of power is created when throwing a ball. Slide…

When teaching the power clean there are three phrases that must be taught in order to be successful with this lift. The three phrases are the rack position, jumping position and hang position. All three phases when combined will result in perfect form and complete the lift of a power clean. When teaching this lift the lifters must not use any weight, it is recommended to use an empty bar to properly learn the movements. The teaching progressions starts with the hang position then progresses to…

surface area by 16 and get 8,235,496,645 km away. • The sun’s mass is about 2.7 x 107 times greater than the moon’s mass. The sun is about 400 times farther from Earth than the moon. How does the gravitational force exerted on Earth by the sun compare with the gravitational force exerted on Earth by the…

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 abducted and it’s elbow extends. The deltoid muscle…
