The rolls of paper used are thermally reactive, like typical cash register paper, not plain adding machine tape. The mass must fall gently into padding and never knock against metal parts. The bob should hang slightly toward rear of center in the pocket. This must be done every time the device is moved since the floor and rolling base are not uniform. ALWAYS USE PLUMB BOB TO PLUMB APPARATUS PRIOR TO TEST DROPPING THE MASS. Always connect the power supplies properly and route wires neatly. From the reference spark, carefully measure the positions of all the. The time interval between sparks is then t 0:0333s. The spark timer is timed to spark 30 times per second. Label the posi-tion there as y 0 0:000m and the time associated with it as t 0 0:000s. From this, the acceleration due to gravity can be found: Also required. Select the rst clear and well dened spark as your reference spark.

Be prepared to install new wiring if any of the old are loose or fatigued. Download the Lab Manual for this experiment (4 pages PDF) from. Move and store the apparatus with great care. The wires on the freefall tape generator are very fragile. Some instructors prefer fresh tapes that have not had points circled or numbered previously.
Power Supply, Freefall Spark Generator/Timer Thus, the acceleration due to gravity may be found by finding the difference between at least two instantaneous velocities and dividing that by the time interval between them (friction being considered negligible). In this experiment I set my spark timer to 60 hertz. Since acceleration due to gravity is uniform, the average velocity is also equal to the instantaneous velocity at the midpoint of the chosen interval. Therefore proving acceleration due to gravity is the same for any mass. Students measure the distance between marks on the paper in order to calculate the average velocity of the mass. Discussion: An object dropped near the earths surface will. Measuring acceleration due to gravity using a freefall apparatus. Theory: Acceleration is defined as the change in velocity of an. The position of a freely falling mass is recorded by a high voltage discharge through the mass and an adjacent strip of paper every one-sixtieth of a second. In addition, one will be able to compare theory with experiment for constantly accelerated motion. Apparatus: The apparatus needed include an acceleration timer, paper tape strip, and a mass.
