PHYSICS PROJECT FOR Physics department TERM 1 Acceleration due to gravity of a freely falling body Grade (11 General 5 ) : . . . . . . Time: – 45min. Mleih School Free fall Lab Name : wedad abdulla Using the simulation provided in the following link https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html Objectives: 1. Study the nature of uniformly accelerated motion. 2. Determine the acceleration of gravity (g). 3. Learn to analyze graphical results. INSTRUCTIONS: 1Open the following link: https://phet.colorado.edu/sims/html/projectilemotion/latest/projectile-motion_en.html 2From the home page of this link, click on lab, from lab window use the provided controllers to adjust the height (y) and the velocity of the lunched ball, the mass, the objects shape. 3Adjust the first height at 2m and the velocity must be at zero. 4Release the ball and use the time meter (control the time meter and fix it at the final point of the ball) to measure the time needed for the ball to travel 2m in vertical direction. 5Record your data in table 1. 6Change the height (y) to 4m, release the ball and measure the time needed to travel 4m in the vertical direction. 7Record the new values in table 1. 8Repeat step 3 to fill table 1. 9Use Excel software to plot the relationship between Β½ t2 and y or you can manually plot the graph using a graph paper. 10- Calculate the slope using Β½ t2. trial Y(m) 1 2 3 4 5 6 2.0 4.0 6.0 8.0 10.0 12.0 t(s) 𝟏 𝟐 2 𝒕 (𝑠 ) 𝟐 7 14.0 β€’ Attach the y and 1/2t2 graph below β€’ Find the flowing: – The slope – The 𝑔𝑒π‘₯𝑝 – Define the term β€œfree fall”. ———————————————————————————————————————————————————————– Hints: Watch the you tube video to perform the simulation. https://www.youtube.com/watch?v=XI-DjTKKK0E
