Yes, the steel ball rolling on the counter top moves with a constant velocity.The steel ball took 0.4 sec to cover a distance of 20 cm. The formula to calculate average speed equals to total distance over total time. So, 20 cm divided by 0.4 sec equals to 50 cm/sec. So the speed of the ball is 50 cm/sec. Next, at the distance of of 60 cm the ball rolled across the counter top in 1.2 sec. So, the speed of the ball is 50 cm/sec. Furthermore, at the distance of 100 cm the ball rolled in a total time 2 sec. So, the average speed was 50 cm/sec. In addition to this when you graph all of these points it creates a straight line. The scientific principle states that velocity is speed and direction. It is clearly stated that the speed is constant at

The acceleration for each mass varies in number but are fairly close to each other as seen in table one. Table 2 displays the average acceleration and deviation of each mass. Figures two and three give sample position and velocity time graphs of each mass. Figure four displays the error margins for each mass. From the graph you can conclude that acceleration is not constant because a straight line cannot be drawn between each error margin.

Pennings then took his dog to the park and threw the ball into the lake. He found that the dog took the path with point D, and using his dog’s three fastest swimming and three fastest running times, he found that dog’s fastest average running time was 6.40 meters/second, and his fastest average swimming time was 0.910 meters/second. Next, Pennings plugged these averages into the equation above and simplified to find y = 0.144x. This proportion would be true if Pennings’ dog took a mathematically perfect

The independent variable is temperature. Temperature is either something that is cold or hot. How hot the object or how cold the object. The thing that is changing is the temperature of the tennis ball.

In order to apply our understandings of kinetic and potential energy, we built a rollercoaster. This helped us get a real life understanding as to how these scientific concepts work. Some things that we learned while doing this lab is that having different sized hills in different areas of the coaster will help the marble to keep moving. When building our coaster, we had a lot of trial and error as to how we would build the two hills. We put the first hill immediately after the loop to give the ball enough momentum to keep going.

This is shown in baseball when the fielders are standing or waiting for the ball to be hit. During baseball, when the ball rolls down the field after a ground ball, it is called rolling friction. Rolling friction is the resistance to the sliding, rolling, or flowing of an object due to its contact with another

We conducted our experiment outside so wind might have also affected our results. Air resistance might have affected the ball because the balls might have had small holes and cracks that could have slowed down or sped up the time it took to hit the ground. Also there could have been a systematic error from the device. To improve this experiment we would need equipment that could measure the results more precisely, if the balls used were checked for cracks and holes before and during the experiment and if we conducted the experiment in a room with no

Column1 Spring Constant(N/m) Orange 1416.809091 ±193 Light Blue 1387.899091 ±190 Green 1421.951364 ±193 Using that force to find the spring constant from the tweaked equation mentioned before. Conclusion This experiment confirms the relationship of the spring constant between the objects when projected with a certain field of force. Even with their difference in mass, each ball showed similar results when launched with 620 ±80N proving that spring constant has a relationship between if experimented properly.

A few minor changes but the formula can still be used today to determine an average movement time in almost any scenario. Fitts’ Law implies an inverse relationship between the “difficulty” of a movement and the speed which it can be performed. Fitts’ law has been fundamental in describing one particular aspect of the speed-accuracy trade-off, or the performer’s capability to change the control process so that speed and accuracy are kept in some balance (Schmidt & Lee, 2011, p.278). In soccer you have to outrun, outsmart and outplay your opponent, while controlling the ball, and trying to score. All that can be found by finding the amplitude of the movement, the targets width and the resulting average time will be determined.

I. INTRODUCTION When something is accelerating, the first picture that usually enters our minds is an object that is either speeding up or slowing down. While this may be the case, it is not always true. Acceleration, by definition, causes a change in velocity. As a vector quantity, velocity has both magnitude and direction, so it is not always true that the speed, the magnitude part, is the sole aspect that is changing.

Imagine a ball sailing into the back of the net and the crowd going wild. Do you ever wonder why it got there with such power? Of course you do! Think of Newton’s First Law of Motion. It states that an object at rest will stay at rest, and an object at motion will stay in motion unless acted upon by an outside, unbalanced force.

onclusions made during this inquiry to my knowledge of the game. Having never taken physics in my academic career I do foresee some challenges but I hope to expand my knowledge of both basketball and physics. The aim of this investigation is to determine several different values of the projectile of a basketball shot with fixed angles. III) Parameters and Measurements To simplify the process of identifying an optimal shooting angle and initial velocity to get a ball in the hoop, there are several assumptions and rules that must be made. These assumptions are as follows: • Shots that count are those which go through the hoop without touching the rim • Air resistance will be ignored • Ball spin will be ignored • Terminal velocity will be ignored • The trajectory has no sideways error • The initial shooting velocity remains
