Purpose The purpose of this lab is to find the mathematical relationship between the height from which a round object is dropped, and the speed at which it travels when it reaches the ground. This experiment will achieve the goal by measuring the height at which a sphere will be released on a ramp, and recording the time and distance the sphere will travel when it reaches the ground. By analyzing and projecting the quantitative data on a graph, and finding the best fit line will indicate the existing relationship between the two variables, height and speed. Background The experiment will require the measurement of height, time, and distance. Height is measured as the amount of elevation from the ground and up to the point where the ball will be released. Time is the …show more content…
To set up the photogates, click on the “Open folder” icon that is located at the top left corner. Select the “Probes & sensors” folder. Then, select the folder labeled “photogates”. Thereafter, click on “Pulse time- two gates”. Make a data table to record the variables of height in centimeters, time in seconds, and distance in centimeters. Complete the data table with a total of six different heights, and three time trials for each height. Include the height of zero centimeters in the data table. Have one experimenter stand next to the ramp. The other experimenter at the end of the runway to catch the ball after it passes through the last photogate. Find the 20 centimeter mark on the meter stick next to the ramp, and transfer that same height to where it would be on the ramp, and hold the ball on the ramp at the height of 20 centimeters above ground. Click on the green collect button on the logger pro program to begin recording. Release the ball from that height, and allow it to travel down the ramp, under the first photogate, and then under the second photogate. Once it passes the second photogate, immediately stop and catch the
During the bounce test, the ball may have been released from different points. Although it was supposed to be released from its bottom, human error may have compromised the precision of this measurement. To improve the design of the bounce test, the ball’s bottom point should be marked, and the ball should always be released from there. During the ramp test, the ball may also have been released from different points. Although the ball was supposed to be placed on the ramp so that it would be released from the front, human error may also have compromised the precision of this measurement. In addition, human error may have caused unintentional and unnecessary force applied to the ball. To solve these design issues, a door should be made that holds the ball at a certain position for a fixed amount of time before the experimenter released the ball. During the catapult test, the ball may have been held back for an excessive amount of time. To resolve this experimental design issue, a fixed time to hold the ball back should be
The ball uses this kinetic energy to move up the usually 6 to 7 degree incline to the top of the playing field. The kinetic
Find from the “Starting” and “stopping” locations of where you are going to measure. i.e., I am going to have Charles lay down and I will measure from the bottom of his feet to the top of his head
13. Use the ruler to measure the length, width, and height of the magnet in centimeters. Record the measurements in Data Table 5.
1. The ball has potential energy while momentarily at rest at the top of the path.
Hold one ball beside the top of the meter stick so it does not touch. Drop the ball. Have your partner record the height of the first bounce.
2. Using the protractor, measure the angle of the ramp making sure the angle of the ramp is 10˚.
Following the calf measurement and before the actual vertical jump, the vertical jump height was predicted. The calf measurement was found on the x-axis then the measurement was
5. Tie one end of the 60-cm string to the mass. Place the mass on a table below
The variable y represents the height h, and the variable x represents time t; also the coefficients a, b and c have the values:
Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes. Another key measurement of this lab was to teach the
8. Conduct experiment a second time with catapult pulled back to 90 degrees. (Half way back)
First step is the easiest concept ever and it is placing the on the ground. Your second step is approaching the ball. When
In order to perform this lab, the students will require a measuring tape and calculator.
Theory states that T and d are related by the equation: T2 = kd3+ (4π2 l)/g where g is the acceleration of free fall and k is a constant.
