Physics Lab Report On Using A Simple Pendulum Model

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

Corresponding to the visual aspect of Pendulum Music, four performers pull back strings in which the microphones attached at the end, after that they let these pendulums swing. In terms of the pendulum through physics, a simple

Q, the angle between two known masses is directly proportional with the of two known masses.

Why do some pendulums swing faster than others? Is it a heavier mass, degree dropped, or the string length? We determined that the shorter the string length, the faster the pendulum swings. The longer the string length, the slower the pendulum swings.

The angle used was small, so we assume that sinθ ≈ θ. This will be a source of errors, but it should be precise enough and it will make calculations much easier. As the pendulum is going to the right, we’ll assume the equilibrium position is 0, so the force acting on the mass is negative. Therefore

The force behind the pendulum can be viewed through the different trends throughout history. If, for example, we take a look at the Enlightenment era and how the literature and ideology morphs into that of the Romantic era, events and their reactions can be studied. The Enlightenment era was also referred to as the Age of Reason, due to people taking on a more secular and logical point of view. This was largely a philosophical movement, during which time there was also a great emphasis on causation versus correlation, and both of these are exemplified through Voltaire’s, satirical, Candide. Briefly, Candide follows the story of our main character, Candide, as the love of his life is taken away from him and he journeys in an attempt to get her back. He travels the world and comes in and out of riches, and all throughout this work there are competing philosophies at play, each portrayed by a different character. The character Pangloss represents the world of optimism, believing that

In our data, the least mass of 10 grams had an acceleration of -6.456 m/s2, followed by 50 grams with an acceleration of -9.133 m/s2, followed by 100 grams with an acceleration of -9.414 m/s2, lastly 200 grams had an acceleration of -9.614 m/s2. The group data did not have outliers in the average velocity values which were used to find the acceleration.

Gross. And…gross. Then our guy looks up: above, he notices that a picture of Father Time has been drawn on the ceiling, except that, in this case, his scythe has been replaced by a pendulum. Oh, and anti-bonus, the pendulum is slowly descending toward him.

Since this graph does not show any outliers, I thought that the line of best fit should be polynomial since the polynomial curve. I think this because the curve passes through most of the data points and is the closest R2. These are a bigger difference in the value of 0,02 cm and 0,04 cm. I think this happened because the holes that were being blocked by the overlapping of the cloth in value 0,04 were more than in the value of 0,02 cm. The more holes getting blocked by the overlapping of the cloth will cause the light to not be able to pass through which then causes the results to be low.

Gravity is responsible for a number of things such as our weight, rainfall, the turning of the planets, and why objects fall. Proven already, that if an object is in free fall the only force active is gravitational force. And when force is thrown into the mix and acts on gravity it cause an object to accelerate or speed up. Hence the purpose of this lab is to prove that an object under the impact of gravity will accelerate at a constant rate. Acceleration will also be measured and compared to its actual value 9.8 m/s^2 , the value is negative because gravitational acceleration is downward and noted by as a=-g. It is predicted and expected that the outcome for this lab is that the ball free falling would have a negative velocity and then become

where m equals the mass in kilograms and a equals the acceleration due to gravity, 9.81 m/s2. Record your calculations in your data table. Next, use the equation:

By definition from wikipedia, a pendulum is a weight suspended from a pivot so that it can swing freely. On the more spiritual aspect of a pendulum, it is exactly that, only the weight is normally a semi precious stone such as a clear crystal quartz, amethyst, citrine, smokey quartz or other various stones. A pendulum is usually six to eight inches in length, having the weight on one end and a pivot on the other that allows the item to freely swing.

To determine the acceleration of the pendulum, the equation for the period of a pendulum was used. Acceleration was derived so that g = L / (T / 2)2 (Appendix C Figure 1). The variable L represents the length of the pendulum to the center of mass, T represents the period of the pendulum, or the time of a full swing, and g represents the pendulum’s acceleration due to Earth’s gravity. In measuring the length of the pendulum, measuring tolerances occurred. The length of the pendulum was found to be 0.450 m, however because a meter stick was used, this measurement is inaccurate by +/-

The experiment concluded that the center of gravity of the meter stick did not change although the equilibrium was required to be re balanced once the masses were added. Depending on the mass at one end the distance further away from the center changed. If the mass on one side was greater than the mass on the opposite side the clamp from that side would have to move further away from the center in order to recover the equilibrium. There was a slight percent difference when the torque for both sides were calculated. The cause of this may have

Introduction: In this lab we were trying to prove right Newton 's Second Law which is F=ma. We had used mass and force to test if the law was would match up with our experiment. In the first experiment we used a car and put a certain amount of weights in it to see how much it would affect the mass, time and velocity. In the second experiment, we stretched a rubber band from 1cm to 5cm and released the car from the length of the rubber bands to calculate the time and velocity. In both problems to calculate velocity we used, 1 cm divided by the time calculated by the photogate. Our hypothesis was that if more mass is added, then acceleration will decrease and if force increases then acceleration will also increase. In both experiments we had calculated the velocity. Since acceleration is the rate of which velocity either increases or decreases, we could see if the car was accelerating or decelerating in the experiments.
