Angular Versus Linear Relationship

428 Words2 Pages

He went over 4 types of relationships between linear and angular kinematics – 1 Displacement (s or d=Θr), 2Linear Velocity resulting from length of radius (v=rω), 3Linear Velocity resulting from angular velocity(v=rω), and 4 Angular velocity resulting from manipulation of length of radius (ω=v/r). Relationship #1 – Displacement S or d=Θr (Θ, the angle measured in degrees or radiants or revolutions and (r) radius measured in meters). In the video he used figure 11-15 from our text (the baseball bat). If the angle stays constant, you can increase the radius and have greater displacement, shorter radius less displacement. Relationship #2 – Linear velocity (v) resulting from length of radius …show more content…

The longer the bat (r) the greater displacement. However, keeping with the bat example, the athlete must be able to swing it while maintaining an angular velocity and not at 0. Relationship #3 – Linear velocity (v) resulting from angular velocity (ω) V=rω The greater the angular velocity, the greater the linear velocity to the object. Longer radius and greater angular velocity creates a greater linear velocity. Relationship #4 – Angular velocity (ω) resulting from manipulation of length of radius ω= v/r An increase in radius (or the length) results in a decreased angular velocity and shortening the radius increases angular velocity. I really liked the professors take on this concept. He gave two awesome examples of this relationship one he used a fly swatter on fruit flies versus a bigger insect and another example of boxing – the jab versus the

The measured tensions were normalized relative to the maximum tension and the lengths were normalized relative to the length at which maximum force was generated (Ln = 29 mm). The measured data and expected data were plotted together (Figure 3). Correlation between measured and expected tensions at the same normalized lengths was determined for the three expected segments of the length-tension relationship.2,3,4 This was done using piecewise linear regression and yielded r2isometric = 0.956033. The fitted curve for the isotonic experiment resulted in r2isotonic = 0.960557. The F0 was 19.5 N for the fit and 6.35 N for the guess.

Rotating objects Rotating an object allows you to move an object around in a fixed position of the screen in short it allows me to move the object without altering the position the object sits in on the world. 1.4. Transformations – move Transformations can be accessed by right clicking the object that is selected. The transformation move allows you to move an object around freely from the currently viewed aspect.

First the ball had a small hole directly in the center and the rod had an uneven end these presented challenges for getting an accurate measurement in step III. Second the errors in the measurements were carried through and expanded by the calculations performed. The obtaining the volume via the displacement method was only one step without calculations. Thus I believe the displacement method produce better measurments. 4.

In the first activity, I determined the circumference and tangential speed of points on spinning DVDs to demonstrate the rotation curve of a rigid body. For instance, the DVD with a radius of 4 has a circumference of 25.13 cm and a tangential speed of 1933.08 cm per second. During the activity, I noticed as the radius increased, the tangential speed also increased. I also noticed the shape of the rigid body rotation curve was linear.

The distance after contact is usually less with a wood bat. Statistics say that a wood bat has a slower exit velocity than metal which translates to less distance. The average speed the baseball comes off the wood bat came out to be 98.5 miles per hour (Russell). On the flip side of that, metal bats have a larger sweet spot on the bat which creates a higher exit velocity. The higher exit velocity averages between 100.3 miles per hour and 106.5 miles per hour (Russell).

In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.

As the arm rotates, the things in the thing experience centripetal acceleration which causes it to move out. The initial release position is such that the beam on the counterweight side makes an angle of 45° with the vertical. There is a lot of math required in finding the trajectory of the arms through. The trebuchet reached Europe during the early Middle Ages, or Dark Ages, in 500 AD and was used extensively by the French.

Students have to measure the distance between centers of the pole to the center of radial at the range of one. Use the length and diameter measurement to find out the radius of the rotation (R). After measuring the mass of the hanging mass, reattach the hanging mass to the string and attach the spring from the top of the cross arm. Before attaching the spring to the hanging mass, have to adjust the hanging mass to the pointed tip of the cross arm, it has to be exactly over the radial indicator.

Topic: What’s Better Aluminum or Wood bat? With baseball being one of the most popular sports on the planet, many people are familiar with the different types of bats, which are wood and aluminum. Though many people argue the aluminum bat is better it rises the question, which is truly better, wood or aluminum? This papers will focus on the analysis of wood and aluminum bats.

The specific motion used for this analysis is a baseball pitch by Jake Arrieta who plays for the Chicago Cubs (https://giant.gfycat.com/BelatedWeirdKookaburra.gif). His characteristics: male, height is six foot four inches, weighs 225 pounds, pitches and bats with right hand, age is 30 years old, and has been playing for seven years. In order to produce enough force, the pitch has to go through multiple phases in order to generate it.

Slope formula is Y2-Y1/X2-X1. This means that any two points picked, once subtracted and divided will give us the velocity units. It can also be concluded that x = vt +x0 is the equation of motion for a constant velocity. This is true because the equation was derived from the x vs. t graph that was linear. y

These dimensions, combined with the type of ball each sport uses, results in batters having roughly the same amount of time to react to the ball (at the professional level). Softballs do not travel as fast as baseballs because of their size, but the shortened distance makes hitting a softball just as hard as hitting a

This simile can go two ways. One way it could be presented is the young boy being spun during the dance and is trying to hold on tight. On the contrary, this simile can also be taken as the young boy was staying strong through excruciating pain. Finally, the final way Roethke presents his somber tone is through a possible extended metaphor.

My career goal is to one day become a lawyer. My road on this career path began when I attended Queensborough Community College majoring in Criminal Justice. At the time my aspirations was having a career in law enforcement. After receiving my associate degree, I continued my education at SUNY Old Westbury majoring in Criminology. It is here, where I learned more about criminality from a systematic perspective; but also from a sociological view.
