To record and compare two methods of measuring the acceleration due to gravity. Using the simple pendulum and ticket timer experiments to gather these results Background Research:
Motion with constant acceleration may be described by the following relationships: Consider the following scenario: A motion sensor is located at the top of the track, so the cart accelerates away from the motion sensor. Include the following in your ejournal: Sketch the following graphs: Position change in x vs.
Answer the following questions: Will the position vs. What will the slope of the velocity vs. What will the slope of the acceleration vs. Constant Acceleration on an Incline: Plug the motion sensor into digital channels 1 and 2. Make sure the yellow-banded plug is in channel 1. Raise one end of the track by resting it on the lab jack.
Make sure the lab jack is set to its lowest position. Mount the motion sensor at the upper end of the track. Tilt the sensor so it's directed along the track. It should have a clear view to the end of the track.
Open Capstone and open the Hardware Setup tab, which is on the left side of the screen. At the bottom of the screen, set the sample rate to 50 Hz. Go to Recording Conditions, select Stopping Conditions, and set the stop time to 3 seconds. Set three of them to be graphs. Make one of them position vs.
Make sure the standard deviation box is selected. Place the cart just below the motion sensor. Point the spring-loaded bumper downhill, away from the motion sensor. Click the Record button the instant after the cart is released from rest.
Try not to move your hands in front of the motion sensor, as the sensor may track your hands instead of the cart. Insert a screenshot of your graph into your ejournal.
|gravity | Definition, Physics, & Facts | ashio-midori.com||Computer with Excel unless you want to graph by hand! Procedure Stack some books and set one side of the molding on the books to create a ramp.|
Discuss with your partner what is happening to the cart in each section of the three graphs. Call over a TA or instructor and explain your conclusion to them.
Directions for Measured Mean Acceleration On the graph of acceleration vs. It's fine if it's somewhat noisy. Record the mean and standard deviation of the acceleration graph.
The mean in the statistics box may only display one digit beyond the decimal point. If so, open the Data Summary tab on the left and select Acceleration. You will see a gear button come up. Click on it and under Numerical format increase the number of fixed decimals.
Measure from the table to the lower edge of the track.Department of Physics, University of Utah, Salt Lake City, , UT, USA (Dated: March 6, ) Using a simple pendulum the acceleration due to gravity in Salt Lake City, Utah, USA was found to be ( +/) m=s2.
The model was constructed with the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum. Experiment to measure the acceleration due to gravity Introduction. To measure this acceleration we will drop a magnet and measure the time taken for the magnet to travel between two points.
From my physics text book I know that a simple pendulum has a period that depends only on its length, l, and the constant acceleration due to gravity, g: I measured T = s and know that g = m/s/s, so I can solve for l, the length of the swing.
The purpose of this experiment is to have you determine the acceleration due to gravity L02 Acceleration Due to Gravity on an Inclined Plane 4 Hold the cart, flat side facing the sensor, 50 cm away from the sensor.
Determine the acceleration for these carts the same way you have previously. Main Concept. Galileo Galilei is considered to be one of the fathers of modern science due to his extensive research in astronomy and physics.
One of his greatest contributions involved accurately measuring the effect of gravity on free falling bodies. Physics Lab Report Guidelines Summary The following is an outline of the requirements for a physics lab report.
A. Experimental Description 1. Provide a statement of the physical theory or .
