Using Gravitational Force as a Measurement Tool Answer the following questions about the results of this activity. Record your answers in the boxes. Send your completed lab report to your instructor. Dont forget to save your lab report to your computer Activity 1 Record your data from Activity 1 in the boxes below. Enter the data for the sample you used in each trial (5000 rpm, 10000 rpm, etc) in the appropriate columns and the corresponding g-force, number of layers, and position of layers position results. You will need to use the following formula to assist with your laboratory report G-force 0 00001118 x radius of centrifuge arm x (rpm)2 The radius of the centrifuge arm for this instrument is 10 cm.

The aim of this experiment was to determine the relationship between three angles of incline, three masses of a trolley cart and the acceleration of a cart down an inclined plane. The results received from this experiment show that no matter how heavy the cart is; it still has the same rate of acceleration. This is due to the angle not changing during this experiment. Therefore, hypothesis 1 was supported. The results also show that the bigger the angle of incline, the faster the acceleration rate of the cart. Subsequently, hypothesis 2 is also supported. The cart goes faster down a ramp with a larger angle of incline because of the steepness of the slope. The steeper the slope, the more the cart can accelerate.

Using Vernier, we clicked collect while releasing the cart after motion detector starts to click. This was done moving the hand quickly out the path. Using logger pro, indicated which portion was to be used by dragging across the graph to indicate the starting and ending times. Then the linear button was clicked to perform the linear regression of the selected data. The Linear Button was used to determine the slope of the velocity vs. time graph, only using the portion of the data for times when the cart was freely rolling. We found the acceleration of the cart from the fitted line. Record the value in the data table. These steps where repeated 5 mores times. Measured the length of the incline, x which is the distance between the two points of the ramp. Measure the height, h, the height of the book(s). The last two measurements was used determine the angle of the incline. Raise the incline by placing a second book under the end. Adjust the book so that distance, x, is the same as the previous reading. Repeated these steps with 3, 4 and 5 books.

Click on Run Now. Adjust the settings on the simulation for zero damping, high tension, manual operation & no end. Wiggle the left end up and down by moving the mouse vertically one time returning to the rest position.

The last steps the website provides are the easiest to follow because it is something I would've guessed myself; just pull at the loops to even it all out and adjust accordingly.

Once the eye relief distance is known the scope mount may be adjusted to the correct slots on the base and secured. The shooter will then place the top portion of the scope rings on both mounts and finger tighten the screws as this allows for finer scope adjustments. This will allow for the scope to move slightly in a; rotation, back and forth manner so that finer adjustment can be made. The scope should be adjusted to allow for eye relief from recoil.

(4) Remove the bolt cam pin by turning it one-quarter of a turn and lifting

6. Balance tires. Now that the tire has completely aired up and is ready to go it has to be balanced. The balancing machine is a very complex machine that calculates the spin of the tire to the nearest ounce. There are many different cones that are put on the inside of the tire so that it can properly spin without coming out of track. Once the wheel has been secured on the machine you remove all the weights from the inside of the wheel. You can do these either by a weight clamp or a weight knife. You then push the lid down on top of the tire and wait for the machine to figure out if the tire is spinning in a direction that it shouldn't. You then either use tape weights or tack weights, depending on the size of the lip of the tire. Once you push the lid down again and get the balance on the tire to be 0 it's ready to be bolted back

5.Use one hand to hold the tube, and use another hand to support the hanging mass.

Conclusion After reviewing the results from this experiment I can say that my hypothesis was supported. The car travelling the fastest was white car number 4 because it took 2.87 seconds to cover the 50 metres. Once we calculated the average speed of this car we found that it was 62.64km/h, which was above the speed limit in the area. Furthermore, the blue car finished the 50 metres in 4.12 seconds, making it the slowest car that we recorded data on.

Upon reaching the Main Stand, lock down the wheels of the Roll Out Stand (figure 22) so that the Triple Threat has returned to its retracted state (figure 21).

Discussion: When objects are placed under the microscope, it appears upside down and backwards. In part A, the letter E is placed right side up. But, when viewed through a microscope it looks as if it was placed upside down and backwards. In part B, the cotton strands with low power appears sharper when there is less light from the diaphragm. This is because with less light there is a sharper focus and when there is too much light coming from the diaphragm, the object can get blurry and out of focus.

Objective: During this lab Newton’s Law of static and kinetic friction was studied. The static and kinetic frictional coefficients were found for a block while sliding down a track through experimental trials.

with the accepted value of 9.8m/s^2. In the second experiment, acceleration of a cart traveling down a slight incline was measured with a two photogate method. Gravity was calculated and yielded a value of 8.7429, a bit lower than the accepted value of 9.8 m/s^2. The third experiment was

In order to perform this lab, the students will require a measuring tape and calculator.
