PE = - 100 PE= Part II Now redo steps (1) through (v) with an object that is either much lighter or much heavier than the object you used in the first part. Did you get a value close to the accepted value of 9.8 m/sz? To see how close you got we will compute a Percent Error labeled PE accepted value - your measured value accepted value NOTE: This formula has an absolute value which means your PE should always be o or positive. Step (iv) Compute the acceleration due to gravity from your average time in step (iii) using the kinematic formula a 2(distance travelled) acceleration = (average time) a= EIN Step (V) In step (iv) you have scientifically determined the acceleration due to gravity. Step (ii) From your 3 times compute an average time, call it Tavg Sum of three times Targ = ty+tz+t, 3 Tavg =
Measuring acceleration due to gravity lab trial#
Trial # Timets 1 2 3 Question(!) Explain why your times may have differed by a small amount if they did? NOTE: In your lab write up, write out the question before answering. NOTE: Create a similar looking table for your lab write-up. Do this three times creating and filling in a table as below. You now have the height of the ball in meters Step (ii) Drop the ball and with a stopwatch ( your cell phone should have one ), measure the time it takes for the ball to go from that highest hand position to the ground.
Take a long string from the ground to the ball and cut off that string segment, and measure its length in meters. independent of the object's mass) Procedure Part 1 Step () Take a ball or other solid heavy object and put it as high above your head as possible. toward the earth's center ) causing them to accelerate that is speed up) at the same constant rate of 9.8m independent of how heavy the object is (i.e. Transcribed image text: Measuring the acceleration due to gravity Lab Objective You will measure the acceleration due to earth's gravitational force near the earth's surface Theory (i) Acceleration is the time rate of change of velocity and its metric units are or 1s (ii) Earth's gravity is a force that pulls objects toward the ground ( i.e.
