Change Of Momentum Lab Report

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

To determine whether the height at which a marble is dropped affect the size of the crater.

The Velocity Step Test measures gain and the time constant of the VOR by quickly changing the velocity of the chair when rotating left and right. Pre- and post-rotary nystgamus are measured at time constants of 60 and 240 degrees/second. Pre-rotary nystagmus time constant is measured during the 60- and 240-second velocity times and post-rotary nystagmus is measured during the 60- and 240-second stop times. The reason for using 60 degrees/second is to estimate the time constant and gain for the left and right horizontal canals. As the velocity increases, the time constant decreases and a percentage of VOR gain for the right and left can be compared. The test begins by accelerating the patient around 100 degrees/second2 stimulating the right peripheral system. The patient is spun to the right until maximum velocity is reached at 60 or 240

In the first experiment, “ How does mass affect your game?” it shows that the data on “Ball- Mass 3” that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. According to the data, on “ Ball- Mass 1” the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. On the other hand, the evidence shows that the 12 pound bowling ball in “ Ball- Mass 2” has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls.

Seven various household objects were chosen to measure using a digital gram scale. Each object’s mass was estimated by lab students and recorded in data table 4. A quarter, ball point pen, rubber bulb, large paper clip, green crayon, house key and a copper penny masses were estimated and recorded in data table 4. Each object was placed on the scale individually and its actual measurement was recorded in data table 4. As we started estimating the household objects we were often not correct in our estimations. As we measured more and more objects, we got better in our estimations by comparing objects with known masses and comparing them with the unknown

In order to draw conclusions in both situations, you need to determine what makes the marble or particle roll or travel the way it does. For example, in the experiments, if the particle went straight through the gold leaf and in our activity, if the marble rolls straight through the cardboard, you can infer that the particles and the marble didn’t hit the target. However, if the marble or particle bounced off of the target at an angle, you need to be able to use those angles to determine what shape and size the target is and where it is

The data collected agrees with Newton’s 2nd Law. Newton’s 2nd Law describes how the acceleration of an object is dependent on two things: the mass of that object, and the net force acting upon that object. As the mass of an object increases, its acceleration decreases. Our experiment directly relates to and agrees with this law of motion. The starting mass of our object was 653.7 grams, with an average acceleration of 0.8771 m/s².

Nevertheless, the momentum of the carts was conserved, showing that the sum of momentum before collision for the carts was 0.246 Kg.m/s, while after collision, the momentum was distributed between the two carts at 0.10 Kg.m/ s evenly, giving a total of 0.20 Kg.m/s and showing that the momentum was conserved. The small deviation in the decimal place value can be as a result of some experimental or calculation

Marble 5; 5.1g; total mass is 25.9g; total volume is 10.5mL, and volume of Marble 5 is 2 mL. Marble 6; 5.6g; total mass is 31.5g; total volume is 13mL, and volume of Marble 6 is 2.5mL. When analyzing the results it was discovered that as the number of marbles increase the total volume increased due to the increase of particles. The graph shows a straight line which also demonstrates how the ratio of mass and volume will not cause a change in the density no matter how much of the substance is being used. Possible errors that could have skewed the data include the water not being 30mL at first or a broken calculator. If the water was not originally 30 mL then the total volume of the marbles would be incorrect as the number wouldn’t be accurate because of uneven starting points. If the calculator used to find the answers is broken then the answers would all be inaccurate, which would mess up the data.

With our first hypothesis, we conducted an experiment where we dropped the same glass marble into a tray of sand at different heights of 20 cm, 40 cm, and 60 cm. The average width for each height were 2.8 cm, 3.5 cm, and 4 cm. The average depth for each were .7 cm, 1.5 cm, and 2 cm. Therefore, our hypothesis is correct because

We began our experiment by measuring out a piece of cardboard and determining its cross-sectional area. We then taped this piece of cardboard to our object and faced it so it would have drag. We then securely taped the motion detector to the end of the air track so it could accurately measure the acceleration of the object. We then massed the entire object with the tape and cardboard as well as the base and recorded this mass. We also measured the length of the air track in meters in order to calculate velocity later.

The discovery of these laws, laid down a basic foundation for the physics of motion. Newton's three laws of gravity changed the way in which the world was perceived, because of their accuracy in describing many unexplained phenomenons.3 They explained what happens as a result of different variables, but most importantly, they explained why and how these actions happen. Like many of Isaac Newtons ideas and theories, the three laws of motion had a profound impact on the scientific community. The three laws of motions provided an explanation for almost everything in macro physics. Macro Physics is the branch of physics that deals with physical objects large enough to be observed and treated directly.4 This allowed for many new advancements in physics because the foundation had been build for others to develop upon. Isaac Newton published these findings in his revolutionary book “The Principa”. The Principa was revolutionary book because it organized the bulk of his life’s work, More importantly the

The materials necessary for this lab experiment are a meter stick, an empty soda can, a graduated cylinder, a candy bar, and a gram scale. The meter stick is capable of measuring length. In the case of this experiment, the meter stick is to be used to measure one's height and their partner ’s height in inches three times. From there, they have to determine the average of their results, record the range, and uncertainty.

In this experiment, we experimented finding the fundamental quantities of length, mass, and time using many laboratory tools. We used a Vernier caliper, stopwatch, rulerm meter stick, wooden block, metal block, Dial-o-gram, different masses, and circular objects. We took into consideration the uncertainties of many different tools and objects into our experiment. The inherent uncertainties of different measurements and ways to propagate those uncertainties were learned during this experiment.

Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled by the downfall of different masses which will then tell how mass affects acceleration.
