IV. ANALYSIS Calculations
The average time that the basketball took to reach the ground was 0.99 seconds ± 0.09 seconds. The average was calculated by adding all of the times from both trials and then dividing by the number of time measurements. The uncertainty was found to be 0.09 seconds by calculating the standard deviation of all the times with a TI-84 calculator. The distance the ball dropped was measured to be -255.25 inches, with an estimated uncertainty of 1.00 inch. The distance was converted to meters: -255.25in (2.54cm/1in) (1m/100cm) = -6.48 m. The uncertainty was also converted to meters: 1in (2.54cm/1in) (1m/100cm) = 0.03 m. This results in the distance being -6.48 ± 0.03 meters.

The measured value for the force of gravity was -13 ± 2 m/s2, while the accepted value is -9.8 m/s2 1. The sources of uncertainty for the value included the uncertainty of the measurement when using a tape measure, and the random uncertainty that resulted from variations in the timing. The uncertainty was amplified when the values were manipulated in order to solve for the acceleration. Because the timers were operated by humans, the time measurements were not completely accurate. The timer was often started slightly after the ball was released, due to a delay based on human reaction time. The timer would be stopped at a more accurate time because the operator could see and anticipate when the ball was about to hit the ground. Since the timer was started late and stopped on time, the time measurements were shorter than they should have been. As a result this increased the calculated force of gravity, because the distance was divided by a smaller amount. If the experiment was to be done again, the trials could be recorded to produce more accurate time measurements. The recording could be started before the ball is released, with the timer in frame and also started. The time when the ball was released would be subtracted from the time when the ball hit the ground to determine the total time the ball was falling. This method should produce a value closer to the accepted force of gravity of -9.8

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.

The force of the pass was found by Newton’s 2nd law, F=ma, where .1 kg was multiplied by 10 m/s^2. If the force of the pass was 1 N, this means that the stick caught the ball at +1 N, and the ball ‘caught’ the stick at -1 N. The force has the same magnitude and is constant and equal during the pass, but have different directions. Newton’s 3rd Law relates to the equation, momentum= mass X velocity.

However, the evidence supports the contrary. Lincoln Bagley, a member of the Rigby High School Varsity Boys’ Basketball team, endorses the shot clock and states, “It would give the game a faster pace, which would force players to sharpen their skills, become more aware, and become more adept at creating their shot.” The lower amount of time would give athletes a sense of urgency. They would be looking to score unceasingly during their possession. Newly created ways to put points on the board would become part the players, or they would develop better and faster techniques in their current methods.

Hockey Stick Lab Report

If the stick is pulled further back from the the start line then, the puck will travel a greater distance with a greater velocity than if the stick was pulled back a shorter distance from the start line. For example, the Bauer Vapor x60 Composite Stick cause the puck to travel an average distance of 1.432 meters at an average velocity of when +0.716 meters per second when launched from the -0.15 meter mark. However, when the stick was pulled back to the -0.20 meter mark (an increase of 0.05 meters between the starting point and the stick’s launch point), the Bauer Vapor x60 Composite Stick was able to cause the puck to soar an average distance of 2.171 meters at average velocity of +1.086 meters per second. This is much greater than when the stick was only pulled back to the -0.15 meter

I used a stopwatch to measure the time in seconds. I measured the time from when I threw the ball in the air until it landed back on the ground. I faced two problems while testing my hypothesis. One problem I faced was trying to avoid hitting the cars parked in my driveway with the balls. One of the balls did hit the car, but luckily it didn’t damage the car.

Egg Drop Lab Report

550 Words | 3 Pages

To find the momentum of the highest drop, the mass of the container with the egg inside it, 0.600 kg, was collected, and the final velocity of 15.0 m/s was calculated. This velocity was calculated by multiplying gravity by the time it took for the container to fall this distance. The final velocity and mass were then multiplied together to get the momentum, which is 9.00 kg m/s. Impulse is the change in an object 's momentum and can quantify the overall effect of a force acting over a specific time. To find the impulse for the highest drop, the value of the force exerted on the container was calculated by multiplying the mass with gravity, which equals 5.89 N. This force was then multiplied by the time it took for the drop, 1.53 s, which equalled an impulse of 9.01 Ns. The impulse and momentum is the same because, in a collision, an object experiences a force for a specific time interval that results in a change in momentum.

How High A Ball Bounces Lab Report

Marble was 69.76% efficient and wood was 61.34% and glass was 49.00% efficient this shows how marble conserves much more energy whitch increases the rebound height of the ball. The data shows both marble and wood are close to each other in terms of the rebound heights of the balls but on the other hand the results for the glass was very far from the results for wood and marble showing that wood absorbs more energy from the falling ball resulting in the rebound height being less than the marble but what was unexpected was for the glass to have a less rebound height than the wood. The data also shows that there is some random error which might be due to manually dropping the ball. the coefficient of restitution for marble is 0.8289, for wood 0.7832 and for glass is 0.7000 this expresses the elasticity of each material showing that marble conserved the most amount of energy during the collision allowing which allowed for the highest rebound

How High Can A Basketball Bounce Ball

581 Words | 3 Pages

When a basketball is held in the air, it has potential energy and no kinetic energy. When it starts to fall, it starts to losing potential energy and gaining kinetic energy. The bounce factor between a basketball and bowling ball is different in many ways, basketball is inflated with air and made with rubber that are able to bounce with a force on it. Bowling balls are made out of dense hardwood that are not able to bounce. Many more ways that affects a way the ball bounces are the height which the ball is dropped, the ball’s level of inflation, the temperature of the outside, and the surface the ball bounces on.

Measuring Projectile Motion In Baseball

1753 Words | 8 Pages

Kevin Irwin Physics SL: Period 7 May 5th, 2017 Measuring the Backspin of a Baseball and the Maximum Height Reached Exploration: Introduction: Projectile motion is a form of motion in which an object is thrown near the earth’s surface, and moves alone a curved path under the action of gravity only. It is implied that all other external forces, such as air resistance and drag, are neglected, and gravity is the only force acted upon the object, in a downward motion. Due to Newton’s first law of Inertia – “Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it” (Philosophiæ Naturalis Principia Mathematica) – there is no horizontal force needed to maintain

Acceleration Due To Gravity Lab Report

647 Words | 3 Pages

To verify the acceleration due to gravity, a toy car, with various masses hung onto it, was used to calculate acceleration using the formula a = slope x 2. The slope was calculated and graphed by rearranging and using the formula d = vi t + ½at2. After rearranging this formula, the acceleration, or slope, for each mass was calculated, and then after multiplying the slope by 2, the acceleration was used to verify acceleration due to gravity. The hypothesis that was given was that the mass will accelerate close to 9.81m/s2, which is the acceleration due to gravity. The hypothesis was supported by the knowledge that friction was a present force in this lab, acting against the toy car as it traveled across the table.

The Importance Of Air Pressure In A Soccer Ball

My project deals with adjusting the air pressure in a soccer ball, and seeing how far it travels when the same force is applied with varying measurements of air. I am testing this topic to show the pros and cons of having a soccer ball correctly and incorrectly pumped while using it to practice and during games. With my project idea there would have been to many variables while testing, I would have to worry about the amount of pressure and how hard I would have to kick the ball. However, I fixed that with adjusting one of the variables... While kicking a soccer ball it is nearly impossible to kick with the same speed, strength, and accuracy, every time; so I will be making a pendulum like contraption to hit the ball with the same amount
