In contrast, energy is only conserved when certain types of forces are exerted between the carts. Hypothesis: the momentum before and after the collision should be the same. Procedure: 1: Measure the masses of the cars. 2: St up the track and balance it. 3.
After all the trials are completed for the six distances, find the average time it took the ball to reach the end from each point. Repeat this process for the incline of the ramp set at 15°. The independent variables of this experiment are the distances from which you release the ball. The dependent variables are the times at which it takes the ball to roll to the end of the ramp starting from each distance. Cowan 2 At the 10° incline of the ramp for the distance of 96 centimeters (cm), the average time was 1.04 seconds (s).
Jump up again for the next repetition. Step 5 - At the completion (the last rep) of the required set, blast off as high as you possibly can. For example, if you are required to do 1 set of 15 repetitions, you will do 14 Squat Hops (3-5 inches per jump) and on the 15th Squat Hop, you will blast off as high as you possibly can. Leapups (with/without rope) This exercise can be done without the use of a jump rope if you desire. When jumping, keep your hands by your side or in front of you for assistance in jumping and follow the same procedures just described.
Lab 7: “Newton’s Second Law” Newton’s Second Law Purpose: To find the graphical and mathematical relationship between the Net forces applied to an object, its mass and acceleration. Variables: Independent: -Hanging mass Dependent: -Acceleration -Force pulling on cart Materials: * * Dynamic Cart with pegs * Force Sensor * Motion Detector * Computer with Logger Pro * Lab Pro * Ramp with Pulley * Mass Sets * String Procedure: 1. Assemble the Ramp and pulley system as shown. Attach proper length of String to the Force Sensor, and add a loop at the opposite end for attachment of various weights. 2.
5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
AP Physics C Lab Report i. Purpose: To investigate the relationship in Newton’s Second Law ii. Materials: Pasco track and cart, endstop, pulley, string, washers, lab pro with motion detector, logger pro iii. Procedure: 1. Assemble the materials as shown in the diagram to the left.
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
Compare the serving size to what you would normally eat. For example, if you food item is a candy bar and you’d typically eat the whole candy bar, yet the serving size is 2 servings (4 points). • The serving size is 1 cup which is around the same amount I would probably eat in a bowl at one sitting. 10. Define nutrient density (4 points).
Three repeated trails for each mass (Step 5) 7. Removing the previous clay and apply the 15 g clay. 8. Repeat step 5-6 for all the other clays. 9.
A total of 15 oscillations were counted and the time it took to complete those was measured. This was repeated and the average of the two times was taken and divided by the number of oscillations to find the period. The procedure was repeated using masses of 20 g, 30 g, 40 g, 50 g, and 60 g. It was found that as the mass load on the spring increased the period also increased. From the data collected at this point in the experiment, it could be concluded that both period and displacement from the equilibrium position are directly proportional to the mass load on the spring. Following the observation and calculation of the period, the mass load M was plotted against the displacement x with data from the first part of the experiment.
