Uniform Motion Lab Report

In this series of experiments, we examined the back and forth motion. We analyzed the motion of five objects which included a mass attached at the end of a spring, a swinging pendulum, a ball thrown up in the air, a jumping student, and a cart rolling up and down an incline. Using the motion detector and a computer we were able to come up with graphs of position VS time and Velocity VS time from which it was possible to tell where the velocity or the acceleration were maximum, and whether they were changing or not. Besides that, the graphs also helped to notice objects that exhibited a similar type of motion.

The purpose of this lab was to test the relationship between velocity, position and time. As well as identify how accelerations affects an object's velocity and time. In this experiment, we will collect data on velocity, speed, and time. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. In class we learned about the principles of acceleration, time, and velocity. Acceleration is an object’s increase in velocity. Velocity is how

Observe the what happens when you vary the rate at which your hand moves or vibrates.

1. Record: Select the BAR CHART tab, select Acceleration from the dropdown menu, and turn on Show numerical values. The bar on the left shows the magnitude of the acceleration, or |a|. The units of acceleration are meters per second per second, or m/s2.

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,

The lab five B was about friction and how its always present. The purpose of this lab wat to explore how friction affect motion. There are three types of friction we discuss like air, rolling, and siding.

Using a measuring tape on the wall each member of the lab group separately stood with either side against the tape and extended the arm beside the wall as high as possible. This height was recorded in centimeters. Next each lab member separately applied chalk to their fingertips, crouched down beside the tape on the wall, and jumped as high as they could while hitting the measuring tape at their highest point. This measurement was again recorded in centimeters. Then the height the lab member’s arm extended while standing was subtracted from the height when they jumped. This number denoted the vertical height jumped. For the jump height measurements a scatter plot was constructed. In order to do this, the data was again entered into excel, highlighted, insert chart and the first scatter plot choice was chosen. It was then that it was necessary to edit our axes and other parts of the graph. The x-axis was right-clicked and format axis was selected and fixed was selected and 20.0 was entered into the blank. Following this, a trend line was added to the graph by right clicking on a data point. A drop down popped up, and from there add trend line was selected from the choices.

9) Since you are plotting displacement on the y-axis and time on the x-axis, this is an example

The movement that makes this object is a uniformly varied movement, because it is subject to the acceleration of gravity. In these types of movement, the position of the body with respect to time, is described by a quadratic function of the form:

axis be parallel to the ground and the positive y axis point upward. In the time interval from

The simple harmonic motion shows that both velocity and acceleration vectors move in harmony when the speed of the ball is increasing in a linear direction. When speed is decreasing, the vectors become

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

When the mousetrap car moves down the track, the speed of the mousetrap car decreases, therefore my hypothesis was supported. At 1 second, the mousetrap car was traveling at a speed of 3.2 m/s. At 2 seconds, the mousetrap car was traveling at a speed of 2.35 m/s. At 3 seconds, the mousetrap car was traveling at a speed of 1.53 m/s. At 4 seconds, the mousetrap car was moving at a speed of 1.2 m/s. At 5 seconds, the mousetrap car was traveling at a speed of .98m/s. “A car will eventually come to a stop if just allowed to roll as the friction between the road surface and the wheels causes friction that causes the vehicle to stop,”(Examples of Rolling Friction). The evidence supports the claim because the wheels of the mousetrap car are moving

To test Newton’s seconds law if whether changing the mass or the force affects the acceleration of an object or a trolley in this case to increase or decrease.
