Lab Report Acceleration Of Gravity

Once in the gym, Rachel set up the popper with the small wooden ball, Jonah again holding the meter stick nearby. I again recorded a video of the ball’s flight but from a greater distance. The group then watched the video in slow-motion and determined the peak of the ball. The height was determined by setting up a proportion; for example, if the meter stick was about .005m tall on the video, and the ball flew to a height of about 0.02m on the video, then the ball flew to a height of 4.00m. This method removed much of the precision of the measurements: the group could not see the ball well from the distance at which the videos were taken and the measurements of the meter stick and height on the videos were estimated rather than truly measured. Despite lack of control over the values, here are the values we recorded for each ball, adjusted to 3 sig

Moving along, to the second experiment, “How does force affect your game?” concludes that using a 10 pound ball applying strong force provides a velocity (m/s) of 3.2, a result of 25 (J) for the kinetic energy, and 5 bowling points

There were many opportunities for error within this lab due to the procedure the group decided to follow. However, the percentage error was not very significant, with a 1.12% to 6.71% difference between the actual and predicted velocity. The slight difference between the percentages could have been a result of parallax, instrument resolution, environmental factors, and the lack of trials. Once major source of error was the group’s decision to bypass collecting many data trials in the interest in time. This may have introduced biased sample fallacy into the conclusion because there were only two trials per a flying toy and which was little evidence to support the statements made about the relationship between velocity, acceleration, and circular motion. For the next lab, the group plans to conduct at least three trails and then use the average to avoid this bias. Environmental errors present during this lab included classmates walking into the flying toy while the group was collecting data,

An experiment was set up with the goal to prove a hypothesis created, which stated that the mass of a marble would not have any effect in the acceleration of that specific marble as it moves down a ramp. During the testing of the hypothesis, the data collected demonstrated that the acceleration of three different marbles with different masses were nearly identical, which reinforced and proved the hypothesis. Acceleration is the rate at which the velocity of an object changes, and velocity is the speed of an object in a specific direction. To test the hypothesis, a marble had to be released right behind a photogate on a ramp, which was placed on the tenth hold. As a consequence, it was impossible for the marble’s time to be recorded with an

An object that has rotational equilibrium, or is balances, has a net torque of 0. The torque of an object is directly proportional to the distance from the applied force to the pivot point, the applied force and its angle; and the formula is T=F*d*sinθ. In this laboratory, we unbalanced and balanced a meter stick by hanging different masses from different distance of the pivot point. In addition, the mass of the meter stick was found using the torque formula.

This great invention had to have a lot of thought put into it because precautions must be made to assure that the pendulum is not acted upon by any outside forces besides gravity. Constructing a mini pendulum for an experiment is very hard to do because of the precise measurements that must be made to ensure the ratios are correct and that it will swing where it is supposed to swing. For example, to start the pendulum moving, it is usually held at an angle by a string, and then burned to release the pendulum. Letting go from one 's hands, or cutting the string, could give the pendulum momentum that is not right in a particular direction creating a variable and inaccurate results. A heavy pendulum on a long, rigid wire will continue going for long periods of time, but air resistance will eventually cause the motion to lessen and stop. Museums usually use an electromagnetic drive to keep the pendulum moving. This provides additional energy to the pendulum but doesn’t affect its direction of motion.

Galileo discovered, if you drop two objects of the same mass from the same height, they will hit the ground simultaneously, as Earth's gravitational pull on all objects is with the same force (9.807 m/s²). Knowing this, the mass of a pendulum will not affect the length of the period. If I drop a pendulum from a higher angle it should have more potential energy and move faster than if I dropped it at a lower angle making the period shorter, right? Well, yes and no. In this case, the bob is moving faster, but it's a longer distance to travel. So the pendulum will move faster but because it is a farther distance to go these factors will even out making the period the same length no matter the drop angle. The book and video specifically mentioned the length is the single factor that will change the period and speed of the pendulum. This can be proved because the bob has a farther distance to go without going any slower or faster. The actual speed isn't varying but due to the farther distance, it takes longer to complete one cycle. From this information, I can conclude some pendulums swing faster than others due to the length of the pendulum and nothing

The air pressure inside a basketball has the biggest affect on bounce. The purpose of conducting this experiment is to determine if a basketball with a greater air pressure (psi) inside the basketball will bounce higher. The hypothesis for this experiment is 'If air pressure is decreased inside the basketball, then the bounce height will decrease as well'. I have participated in numerous inflatable ball sport activities and from personal experience this has enabled me to make an opinion on the results of the experiment, which is expressed in the hypothesis. A video camera was set up on a tripod, this was the main means of collecting the information by recording the bounce of the basketball after being released from a height of 2.7 meters in front of a measuring stick. The experiment was commenced with the basketball inflated to 12 psi and then the psi was decreased by one unit until the basket ball was measuring zero psi. It was essential that at each level of psi the basketball was dropped three times to gather an average resulting in more reliable data. When conducting this experiment the findings revealed the hypothesis was proven correct. When the basketball had the greatest amount of psi (12) it bounced the highest with a average height of 186.7cm. When the basketball had the least amount of psi (zero) it bounced the lowest height of 16.7cm. The results of this experiment provide valuable information to basketball players as it identifies that having the right

When the experiment is undertaken the distance from the ramp to the landing position of the ball is recorded (value d in diagram 1). This means that the formula, Xv= X1+Vvt +12at2 can be used to find the vertical component, however, (t) time is required for this formula. Using the equation v=dtthe time can be found.

A pendulum is a bob suspended by a string from a fixed point and behaves in an oscillating manner. When released from an angle away from its equilibrium, it swings side-to-side in a periodic motion. The time it takes to complete one full swing is considered the period and the purpose of this investigation is to discover the effect of the string length on the period of the pendulum. This will be accomplished by recording and analyzing data with the use of data tables and graphs.

Kassandra Whiteford Dr. Ruzhitskaya Foucault Pendulum Experiment 1-30-18 Support of Foucault’s Pendulum The Foucault’s Pendulum was named after French Physicist Leon Foucault (Sommeria). He created the experiment to prove that the Earth is in a constant state of rotation. The experiment was simple, a Pendulum was created with a weight on the end of a wire which was attached to a fixed point on the ceiling, once set in motion it continued to move and slowly rotated its position.

The pendulum was pulled to about 15 cm from the motion detector. In case of the mass on a spring, the mass was pulled till just a few inches away from the motion detector.

A simple pendulum consists of a mass that is attached to a string of length ‘L’ that is fixed to a point, in this case, a cork suspended by a clamp stand. This allows the mass to be suspended vertically downwards and allows it to be displayed at an angle that it swings. A period ‘T’ of oscillation is the time required for one complete swing. For this to happen ideally its mass must swing from an angle that is
