After I finished my weekend homework, I decided to watch the NHL Network, and the NHL was doing a special on Connor McDavid, the phenomenal young captain of the Edmonton Oilers, who is only nineteen years old. During the special, the analysts of the program described Connor as the fastest skater in the NHL, and he accelerates at a rate of 3 meters per second squared, from a complete stop. Thinking of the rate of his tremendous speed, I was wondering how fast that he would get if he traveled at that rate of acceleration for 10 seconds. Connecting back to class and the kinematic equations, I remembered the equation that allowed me to figure out Connor’s final velocity: vf = v i +at. Knowing that Connor’s initial velocity is zero, that his acceleration is 3 meters per second squared, and the time that I wanted to figure out his speed for was 10 seconds, I filled these numbers into the equation to get, vf = (0 meters per second) + (3 meters per second squared)(10 seconds). Next, multiplying 3 meters per second squared by 10 seconds, and adding zero m/s for the initial velocity, I found out that Connor’s final velocity was 30 m/s, which is extremely …show more content…
After doing this problem, I found that I am very comfortable using the kinematic equation of vf = v i +at, when I use this equation I find that I always get the right answer for the problem, which is great, and I have no further questions to help me understand this
The purpose of this lab was to test the relationship between velocity, position and time. As well as identify how accelerations affects an object's velocity and time. In this experiment, we will collect data on velocity, speed, and time. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. In class we learned about the principles of acceleration, time, and velocity. Acceleration is an object’s increase in velocity. Velocity is how

This is established by analyzing the kinematics and activation levels at various speeds, positions and phases of the wrist shot and skating. These articles provide insight on how activation demands change throughout certain hockey skills and can be applied to a training routine to improve performance. By using electromyography, motion capture systems and comparing high caliber and low caliber athletes, results such whole body stabilization, increased muscle activation and joint motion amplitude were observed with athletes showing higher skill and
In the United States of America 64% of the population watch football, but no one ever thinks of the physics involved. One common misconception is people think that quickness and speed can go hand in hand, but in fact quickness and speed are 2 different things. Quickness is acceleration and that is the speed in comparison to direction. However speed is the rate of change per second. “Galileo was the first scientist to make a comprehensive study of kinematics” (pg. 27). How does physics relate to football? Football has many examples of how physics can be used to better understand it. another example is acceleration, even more acceleration versus speed. Speed velocity and acceleration are
41328.125 a = 41328.125 m/s^2 Then we take v = u +at where v is the final velocity of an object, u is the initial velocity, a is the acceleration and t is the time from u to v. u=0 v=230 m/s a=41328.125 m/s^2 230= 0 + 41328.125 x
Here, Sy is the displacement in the y (vertical) direction. Since the height of the cliff and the acceleration of the car (gravity) are known, time is the missing variable needed to find the horizontal displacement.
Many everyday activities, and sports involve physics. During the Olympics, you saw the graceful performance done by the figure skaters. Figure skating involves a lot of physics. These principles include friction, momentum, and Newton’s Third Law. These core principles plays a big impact on the performance of figure skaters. Before understanding the physics of the ice skater’s motion, the first thing to comprehend is the skates itself.
a game played on ice and it is done this way for a reason. This is because ice has a naturally low friction, making it easy for hockey player to glide across the surface. As we know, friction is the force that opposes the main force (the main force being the movement of the player). The coefficient of friction between skates and the ice is around .03. Furthermore the ice’s composition assists the player in stopping, speeding up, or turning. When skating, a hockey player doesn’t skate with their legs pointed forward. Instead, his skates are tilted at an angle away from his body. This is because, while moving on ice, the friction force is almost zero and the force being created by the motion is perpendicular to the blade on the skates. The hockey player will use one leg to push and the other to glide, while frequently alternating. If the hockey player wants to travel faster they will angle their skates more. This helps to make the force larger. When a hockey player skates
Speed and agility are integral components of successful performance in a variety of different sports. Speed refers to the ability to move the body as quickly as possible over a set distance. Agility, on the other hand, is the ability to accelerate, decelerate, and change direction rapidly while maintaining good body control and speed. By measuring speed and agility, a fitness professional can target the weaknesses in sport or task performance and use them to alter the training program to make it more individualized to the athlete.
Then I used the work-energy theorem to calculate the energy lost as heat, the work, as an object traveled a given distance on a sticky surface. Friction was a factor in that part of the problem so I drew a free-body diagram to indicate the net force acting on the object (WA-COMP-2009.SCI.1.1.3.H). Finally, I had to calculate the spring constant using the mechanical energy equation one more time, but replacing the gravitational potential energy equation with the spring potential energy equation to determine the spring constant (WA-COMP-2009.SCI.1.1.3.J). Problem eleven required the use of one simple kinematic equation, after I applied the impulse momentum theorem; once I determined the velocity of a skater, I used it to determine the time it took him to travel a given distance (WA-COMP-2009.SCI.1.1.3). Although I lost points on three multiple choice questions, they are no longer a weakness because I reworked the problems and have become proficient
Hockey is much faster and swifter than any other sport. As the players streak across the ice, their powerful shots and passes can send the puck faster than 100 miles [160 kilometers] per hour. A goalkeeper on each team defends his net from the puck going in. They must often make quick slides across the on their skates, stomachs, knees or backs to stop the puck from going into the net. A puck that
Hockey, claimed by many to be one of the most intense and brutal games professionally
“Skating combines elements of athleticism and artistry, requiring strength, flexibility, power, endurance, and grace” as stated by the International Journal of Sports Physiology and Performance ( 2007). Skaters much have adequate aerobic endurance for performances, which can last up to 10 minutes as well as anaerobic capacities that can sustain bursts of energy for the many different types of jumps they present. These athletes commonly incorporate interval training into their programs as it alternates activities between high and moderate intensities, similar to what they will encounter during a performance.
Newton’s Second law states that the acceleration of an object is directly proportional to the net external force and inversely proportional to the mass of an object. Force and acceleration are both vectors and will point in the same direction. Newton’s third law states that forces occur in pairs, so when a force acts on an object there will be a reaction from the object to where the force is applied. The second object will exert a force back onto the original object that is equal in magnitude but opposite in the direction. Newton’s laws are able to yield the equation F=ma. In the case of figuring out the hockey shot a=(Vf2-Vi2)/2Δx, and when you combine the equation together you get F=m=(Vf2-Vi2)/2Δx. All that is needed to figure out the force on the hockey puck is the initial velocity, the final velocity, the mass and the distance traveled. The mass of a hockey puck is .160kg and the length traveled is 17.3 meters. The initial velocity of the puck in my case was 0 m/s and the final speed of the puck was 87 mph measured by a radar gun which converted to 38.89 m/s. With all this information the force could be calculated. F=.160kg(38.89 m/s 2 – 0 m/s 2)/2(17.3m) which equaled 6.99 N or 7.00 N.
