Next we will take two raps of the string on the anchor point and measure the distance from the anchor to the center of the bob and record that measurement. We repeat the process of pulling the bob out a couple inches and start the stopwatch and let it swing ten times and when the bob reaches the same side it started stop the stopwatch again. Repeat this process until you can no longer get an accurate measurement of the swinging bob. Once you complete this process you should end up with a set of data that looks like the list
I found that as the mass load was increased the displacement from the reference position increased. After measuring the displacement from the reference position, we studied periods of vibration. We started by suspending 10 g from the mass holder and recording the total weight on the spring (10 g plus the weight of the mass holder). The mass was displaced about 3 cm from its equilibrium position and released. A total of 15 oscillations were counted and the time it took to complete those was measured.
Measure the weight on the ruler and record it in the data table 7. Put the third mass in the spring and wait until it stops bouncing 8. Measure the weight on the ruler and record it in the data table 9. Repeat the measurement two to three time to get accuracy on the readings. Recording Raw Data: Mass/g (+/- 0.1) | (+/- 0.1) cm/1 | (+/- 0.1) cm/2 | (+/- 0.1) cm /3 | Average cm | 0 | 0 | 0 | 0 | 0 | 49.9 | 1.3 | 1.5 | 1.2 | 0.15 | 99.7 | 5 | 4.8 | 4.4 | 0.30 | 199.9 | 13.5 | 13.7 | 13.2 | 0.25 | 499.2 | 38.7 | 38.5 | 38.9 | 0.20 | Processed Raw Data: Force/newton’s | Average extension m | Error bar (+/-
After we had taken all of our measurements we had to decide which setting we were going to fire the ball at. We chose long. We took turns firing the ball out of the spring loaded gun and calculated the velocity by recording the position degree at which the pendulum swung after the ball had collided with it. We repeated this experiment for five trials and recorded our data. Data: Procedure 1 m = .0657kg | M= .2426kg | y1= .059cm | Trial | p | y2 (m) | y2-y1 (m) | V (m/s) | Xvo (m/s) | 1 | 39⁰ | .145 | .087 | 1.31 | .315 | 2 | 38.5⁰ | .144 | .086 | 1.30 | .315 | 3 | 38.5⁰ | .143 | .084 | 1.28 | .311 | 4 | 38.5⁰ | .144 | .085 | 1.29 | .313 | 5 | 38.5⁰ | .144 | .085 | 1.29 | .313 | Our m is the mass of our ball and M is the mass of the pendulum just by itself.
Place a 10g weight in the “weight bucket”. 5. Pull the string to a 20O angle on the protractor. 6. Using a stopwatch, carefully time 1 period (from A to C to A on the image on front).
Sundback increased the number of fastening elements from four per inch to ten or eleven, had two facing-rows of teeth that pulled into a single piece by the slider, and increased the opening for the teeth guided by the slider. The patent for the 'Separable Fastener' was issued in 1917. Sundback also created the manufacturing machine for the new zipper. The 'S-L' or scrapless machine took a special Y-shaped wire and cut scoops from it, then punched the scoop dimple and nib, and clamped each scoop on a cloth tape to produce a continuous zipper chain. Within the first year of operation, Sundback's zipper-making machinery was producing a few hundred feet of fastener per day.
Lastly we will explore standing waves and how string oscillations become affected by the string mass density. Theory As stated in order above, our first experiment of simple harmonic motion using an oscillating spring setup. By using a mass hanger attached to a rotary motion sensor, we are able to produce graphs and data to attempt to show the proofs for the theories and equations listed in the theory and graph section of the lab. The experiment started with adding 200g and progressively moved up to 350g for five trials. We then collected the data and analyzed the sine graph and the different portions of it and what they meant including the parameters and taking proper data.
Galileo used pendulums extensively in his experiments. Early in his career, he researched the characteristics of their motion. After investigating their behaviour he was able to use them as a time measure device in later experiments. Pendulums are mentioned in both Galileo’s Dialogues Concerning Two New Sciences and Dialogue Concerning the Two Chief World Systems. In these two works, Galileo discussed some of the major points he discovered about pendulums (Morgan, 1995).
As results, I had a VO@ MAX of 42.669, a population average of 37.295, a score of 84 and I was rated as “good.” Secondly, the muscular strength and endurance tests were: the plank (core strength) which was evaluated in 8 stages, the sit ups (30 seconds), the squats test, the push ups test and the standing long jump test. In the plank test, I succeed to do 7 stages on 8. For
Einstein was a physicist, He resided at many countries namely: Germany, Belgium, Italy, Switzerland, Hungary, and The United States of America. He has obtained citizenship in most of the places he resided. He has won some notable awards including a nobel prize in 1921 for his contribution in the field of physics. He acquired interest in science and mathematics at a very young age, When his father gave him a compass and he observed something made the needles move and he began experimenting on how it works. His father Herman Einstein was an Engineer while his mother was called Pauline Einstein.
