Effect of Force and Mass on Acceleration Essay

Abstract In this science science research laboratory there were two principals investigated. The low was the blood surrounded by applied stroller and speedup. The game was the human relationship mingled with plurality and acceleration. To battlefield these two relationships, my partners and I used a dynamic carriage with added big money on it. This stroller was thusly attached to a pulley musical arrangement on a frictionless track where it was pulled by a string bearing stack eitherplace the edge of a t fitting. In the beginning(a) relationship tested, applied pass and acceleration, plentitude was moved from universe on the pushcart to being on the end of the pulley. My partners and I measured the acceleration with the research labQuest computer every time the cart was released. In battle array to test the relationship between visual modality and acceleration, my group added divergent amounts of spile to the cart and measured the miscellanys in acceler ation. From each of the information collected we concluded that force and acceleration assume a direct, linear relationship. We similarly controld that people and acceleration have an inverse, quadratic relationship.Background When my lab partners and I started this lab, we came in knowing some desk slide by information on what we were doing and the concepts involved. We knew that we had to determine the relationships between acceleration in a strategy and the net force acting on the system. We also knew that we had to discover the relationship between acceleration and mass in the system. some major concepts we had to understand antecedent to the lab were Newtons Fist justness of Motion, acceleration, net forces, and inactivity. Newtons first law states that an intent at put down depart lie at hiatus, and an object in motion go out remain in motion, with the comparable speed and nidus unless acted on by an softheaded force. This is classical be apparent moveme nt we were awargon that when an object is moving at constant velocity there is a net force of zero.This gave my group our elemental understanding of acceleration, a rate of change of velocity over time because we recognise that when there is an unequal net force the object must be accelerating/ decelerating. This also allowed my group to understand how net forces work, which is in particular important since this lab consists of net forces that are not zero. Because the track the cart rode on was considered to be frictionless, my group used our prior knowledge to assume that the only unbalanced force in the system was from the naiant tension in the string. My groups understanding that inertia is an objects tendency to stay at rest and resist motion helped us during the lab as well. With this background knowledge we were able to perform the appropriate experiments to gain the even up results for our lab.Purpose The purpose of this lab was to determine the relationship between mas s and acceleration. another(prenominal) purpose was to determine the relationship between the acceleration in a system and the net force that is acting on the system. We wanted to deepen our understanding of these relationships by proving already known theories for ourselves.Hypothesis If the mass of the cart is unploughed constant tho the net force of the system increases ( pause weight unit over the pulley), then the acceleration will increase. The acceleration will increase because a larger force will cause the object to move faster. This is because as the forces bewilder much unbalanced in the plain axis the easier it is for an object to overcome its inertial tendency to stay at rest. However, if the mass of the cart changes but the force is kept constant, then the acceleration will decrease. This will happen because the heavier the object is the more force needed in shape for it to move. Adding mass would increase the objects inertial tendency to stay at rest.Lab Drawing Procedure To test the relationship between acceleration and force (constant mass) my lab partners and I set up a metal cart on a metal frictionless track. The cart had a string attached to it that ran over a pulley, alongside the edge of the table, where it was connected to a hanging mass (as the preceding(prenominal) draftsmanship indicates). We hooked up a LabQuest info logger to the track in order to document the carts acceleration while being pulled by the hanging weight. My lab partners and I then placed two ergocalciferol chiliad blocks on the cart in addition to five 50 gm mess. On the end of the string hanging was a 50 gram mass. The cart was then released from its held position on the track, and the hanging weight caused the cart to accelerate. This acceleration was enter by the LabQuest info logger. My partners and I performed trio trials and then bring the average acceleration. at one time the average acceleration was calculated, we took a 50 gram mass from on top of the cart to the hanging mass. The cart was released and the LabQuest data logger documented this new acceleration. We did this tierce times as well. My partners and I did this until all of the 50 gram masses were transferred from above the cart to onto the hanging string (6 different forces, 15 different trials). After this was established we found the applied force by multiplying the hanging mass by 9.8 m/s2 (acceleration due to gravity). We then plot the points and graphed the data to discover the relationship.To test the second relationship, mass and acceleration, my lab partners and I used the same cart and pulley set up on the frictionless track. We calculated the mass of the cart prior to adding any more mass, which was about five hundred grams. Once we sight this number we added five 500 gram masses to the cart. We released this cart triad times, using a constant force, and had the LabQuest document the acceleration. We then found the average acceleration for the 3 kg cart. After, we removed one 500 gram mass from the cart. We released the cart three times with this new mass and found its individual and average acceleration. We repeated these go until all of the 500 gram masses were removed from the cart, and then tested the cart with no added mass (6 different masses, 18 different trials). Once completed, this data was plotted and graphed, and the relationship determined.
