Physics Lab Report 2016

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.

For example, for trials one and four, trial one had a greater slope and a greater y-intercept. By finding the velocity we were also able to locate when the object was accelerating and decelerating.

2. Read the background information found under the “Question” area first, and then continue on to reading the “Procedure” information posted there as well.

This was due to the formulas used to calculate the actual velocity and acceleration: 2πr/t for speed and v2/r for acceleration. As for the other forces identified within the lab, the force of air resistance equaled the net force and allowed the flying cow to travel at a constant velocity.

T= 40ms, I figured this by guessing cause I could not find any information on how to calculate. So I used the equation for t and plugged in different numbers until I got the 10ms that was already given in the table. t= T x 0/360= 40ms x 90/360= 0.01 x 10^-3= 10ms

1. (6 points) Use the controls under Show Vectors to draw arrows for several different quantities. The velocity vector is drawn in a special way: a big, bold arrow showing its direction and magnitude, plus smaller arrows for its horizontal and vertical components.

13) An airplane increases its speed from 100 m/s to 160 m/s, at the average rate of 15 m/s2. How much time does it take for the complete increase in speed?

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

33. Why is it that a cat that falls from the top of a 50-story building will hit a safety net below no faster than if it fell from the twentieth story?

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:

s, the trajectory of the car along a certain section of the track is given by

After doing this problem, I found that I am very comfortable using the kinematic equation of vf = v​i​​+at, when I use this equation I find that I always get the right answer for the problem, which is great, and I have no further questions to help me understand this

A Betz manometer is used to measure the tunnel pressure, which is given in mm0, which can then be used to calculate the wind tunnel speed. This pressure was given as 20.25 mm0. The barometric pressure was recorded to be 761.5 mmHg, which will be converted into Pascals. The ambient air temperature was taken to be 23.5

J) The altitude decreased by 13 degrees since the previous observation, and the azimuth increased by 13 degrees.

There are two assumptions of the motion analysis technique. Firstly, the bodies are assumed to be rigid, meaning the bodies will not deform under applied forces. By assuming rigid body, parameters that describe the configuration of the system to the translation and rotation of reference frames attached to each body are
