![]() ![]() In your own experiments, you can collect data from shorter or longer distances. ![]() Use your own data to calculate the acceleration of the flashlight you drop. Albert Einstein described gravity as a curve in space that wraps around an objectsuch as a star or a planet. Earth's gravity is what keeps you on the ground and what makes things fall. The time it takes to make that change is 0.33 sĪcceleration = (3.33 m/s – 0 m/s) / 0.33 s = 10 m/s 2 The answer is gravity: an invisible force that pulls objects toward each other. In our case, at time 0.297 to 0.33 s (time = 0.033 s), the distance traveled is from 0.4 m to 0.51 m (distance = 0.11 m). Physicists Measure the Gravitational Force between the Smallest Masses Yet A laboratory experiment captured the pull between two minuscule gold spheres, paving the way for experiments that probe. V initial is the flashlight’s velocity just before it’s dropped, or 0 m/s V final is the velocity of the light at the end of the drop. Students will apply the principles of momentum and impulse to build housing for an egg so that it will survive. Here’s an example using our data (see the table above): It increased understanding of the principles of rotational equilibrium through the calculation of rotational equilibrium in numerous experimental scenarios. If your flashlight leaves a streak of light, only record the location at the bottom of the streak (the streak is a 1/30 th of a second record of the light's fall).Ĭalculate the acceleration due to gravityĪcceleration describes how fast the rate of something changes.Īcceleration = ( V final – V initial) / the time to make this change This lab activity taught the concepts of rotational equilibrium and torques. Notice that, during the first few steps, the flashlight doesn’t fall very much. In the experiment the value of g will be determined using. Now, step by step, record the distance in meters dropped and the corresponding time of the flashlight’s fall. time is thus a straight line, the slope of which is the acceleration, a. The frame you’re now at is time 0s and distance 0m.) This type of assignment is usually shorter than a research paper. The main purpose of a lab report is to demonstrate your understanding of the scientific method by performing and evaluating a hands-on lab experiment. (Note that frame-by-frame players usually let you move forward or backward via arrow keys. A lab report conveys the aim, methods, results, and conclusions of a scientific experiment. That means each frame will add an additional 0.033 seconds.ĭistance Data: In your video player, find the frame just before your flashlight drops. Time Data: Since your camera records 30 frames a second, each frame represents only 1/30 of a second, or about 0.033 seconds. Jessica M Nguyen Partner: Miriam Alvarado Acceleration. Label the columns “Time in seconds” and “Distance in meters.” (See the sample table below.) View Lab Report - Physics 201 Gravity Lab Report.docx from PHYS 201 at Indiana University, Northwest. Make a table with two columns to record your data. Place a marble at the very edge of the table, right next to an open end of the tube. Use a book to angle your paper towel tube to make a ramp near the edge of the table. PHYS LAB 5. CUNY New York City College of Technology. Redo it if you didn’t get a clear view of your flashlight’s light falling straight down. Part 2 Gravity and Mass In this part, you will measure the acceleration of gravity in another way, and also look at the effect of the mass of the falling object. NYC COLLEGE OF TECHNOLOGY PHYSICS LAB REPORT LAB 6: Acceleration Due to Gravity Conducted by: Sean Munusami Lab. Digital video is easy to erase and reshoot. The objective of the lab was to determine the gravitational acceleration constant, g, by measuring the change in velocity of known masses sliding down an inclined plane. Have someone else film the drop with a digital camera (in HD at standard 30 frames per second).Ĭheck your video to make sure you got the shot. If possible, use only one finger to hold the flashlight still until the time of release. Place the light as close to the 0 cm mark as possible and against the measuring tape. Make sure your flashlight is on a non-blinking setting. Turn on the flashlight and point it upwards. \) rather than a rough estimate.Have one partner stand next to the measuring tape.
