Tape a piece of cardboard on top of the glider, as shown in Figure 1.2. Raise the photogate so it is the cardboard, not the body of the glider, that interrupts the photogate. Use just one photogate and place it at x1. Set the timer to GATE. Now D is the length of the cardboard.
Cowan 2 At the 10° incline of the ramp for the distance of 96 centimeters (cm), the average time was 1.04 seconds (s). For the first trial at this distance, the time was 1.09s, the second trial time was .88s, and the third trial time was 1.16s. For the distance of 80cm, the average time it took the ball to roll down the ramp was .86s. For the first trial the time was .86s, the second trial time was 1.01s, and the third trial time was .70s. For the distance of 64cm, the average time it took the ball to roll down the ramp was .62s.
G. Take pulse for 10 seconds and multiply by 6. 120 H. Do 3 to 5 minutes of stretching exercises. I. Take pulse for 10 seconds and multiply by 6.110 J. Run for 440 yards.
Explain what a radian measure represents using the Unit Circle as a reference. A radian measure represents the distance of a radius on the unit circle from the positive x-axis. Radians are mostly associated with pi. 2) How do special right triangles directly relate to the circle? There are two types of special right triangles: 45-45-90 and 30-60-90.
9. Find the average time for each clay with different mass to hit the ground. 10.Find the speed of the parachute in each trial and the random uncertainty from the repeat trials. 11.Plot a graph of mass (x-‐axis) against time (y-‐axis) to look for a relationship. If the first graph is not linear it will be necessary to further process the data and plot further graphs to try to find a
Then drew two intersecting lines perpendicular to each other. 2. Using the protractor I drew the angles of incidences or rays measuring 10°, 20°, 30°, 40°, 50° and 60°. 3. Then I drew a semi-circle on the top of the intersection representing the flexi glass and placed the flexi glass over the semi-circle.
Pendulum Aim: To investigate the time for 1 oscillation for different lengths of pendulum and different masses for the pendulum bobs Hypothesis: The time taken for oscillation is proportional to the lengths of the pendulums Apparatus: * A retort stand * Strings * Masses( big, medium and small balls) * Metre ruler * Stopwatch Procedure: 1. Fix the iron stand on the bench 2. Hang the mass on the end of strings and the iron stand 3. Measure the lengths of pendulum with the metre rule 4. Displace the masses to cause oscillation 5.
In this experiment we studied the motion of a vibrating spring. For the first part of the experiment we hooked a 50 g mass holder to the spring and recorded the total mass on the spring as the reference point 〖 M〗_0. The reference or equilibrium position, x_0, of the spring was then observed and measured to be 21.2 cm. The mass load was then increased by 10 g until the total mass load was 110g. I found that as the mass load was increased the displacement from the reference position increased.
Determination of “g” by the use of a Pendulum This experiment is going to utilize a bob on the end of a string line to determine the value of little “g” by measuring the length of the string and the duration of time it takes for the bob to swing from one fulcrum point back to the same point after swinging 10 times. The justification for the bob swinging 10 times is to generate a more accurate measurement of time. To start the supplies that are required for this experiment are a stable stand for the string to be secured to. A minimum of a two yard line of string to that can be secured to the anchor and a bob and obviously a bob to be attached to the end of the string. We also need a stopwatch to measure the time duration and a measuring tool to determine the length of each experiment.
Physics 201 Section 401 ARCHIMEDES’ PRINCIPLE Jordan Nix Partners: Kelsey Carter and Taylor Pfau Date Performed: November 10, 2014 TA: Andrew Whitley Abstract Table 1 | Mass (g) | Mass Submerged (g) | Mass Apparent (m') (g) | Radius (cm) | Length (cm) | Length Submerged (cm) | Volume (cm3) | Aluminum | 58.50 | | 42.00 | 0.95 | 7.60 | | 21.32 | Wood | 30.50 | 8.85 | 20.00 | 1.15 | 9.89 | 2.90 | 12.05 | Table 2 | Theoretical Density(theo) (g/cm3) | Experimental Density(exp) (g/cm3) | Percent Difference(%) | Aluminum | 2.74 | 3.54 | 29.20 | Wood | 2.54 | 2.90 | 14.17 | Discussion In the first part, a 58.5 g aluminum cylinder was hung from a string attached to a scale and submerged in a graduated cylinder filled with water. The cylinder displaced approximately 17 mLs of water and had an “apparent mass” of 42 g while submerged. Two oppositional forces acted upon the cylinder: gravity drew it downward while buoyant force pushed it towards the water’s surface. Using Archimedes’ Principle that force on a body in a fluid is equal in magnitude to the weight displaced by the fluid, we were able to calculate the experimental density of the aluminum cylinder as 3.54 g/cm3. Measurements of the radius and length of the cylinder provided its volume and theoretical density of 2.74 g/cm^3 which confirmed Archimedes’ Principle.
