Mayra Veintimilla PHY 2001- Professor Miraj Uddin Lab Report #2 Free Fall Objective: To measure the acceleration due to the force exerted by the earth. To find the total force on a mass in mechanical equilibrium. Apparatus: Material Object Drawing Explanation Tape timer A device that marks with graphite dots a paper strip in intervals of 40hz (40 dots a second) or 10hz (10 dots a second). 1 Meter Ruler 1 Meter Ruler: A measuring tool that counts to 0-100 cm and have divisions on millimeters of 10 mm for each cm. Tape A strip of paper used to record the motion of an object over time 100g weight A steel weight with a known weight normally used for generating a known force 200g weight A steel weight with known weight normally used for generating a known force. A force table This is a round, horizontal, circular table, with angles marked from 0 degrees to 360 degrees. It has a metal bolt in the center to keep a small ring (see below) from escaping. • A small circular plastic or metal ring.

Journal: One pulley was initially positioned at 0°. The positions of the other two pulleys were 140° and 270°. These angles were referred to as. Every calculation was done in centimeters and seconds (s). The final findings must be expressed in cm/s^2. To generate a downward slope for the measurements, first assemble the tape timer and position it at a 90-degree vertical angle. After that, cut 20 1.2 m (or 120 cm) long pieces of tape. Next, attach the 100g weight with a strip and run it through the tape timer. After that, release the weight and configure the machine to run at 40 Hz. Gather the strip and count the number of dots in 1 meter for every 100 centimeters. Repeat 9 more times using the 100 g weight and 10 times using the 200 g weight. Once you're done, plot all the data on a graph and use the following formula to determine the average and cm/s^s2. Equation (2xD/(dots/total hz)^2). The following distances should also be measured: 0–4 dots, 1–5 dots, 2–6 dots, and so on, until you reach 8–12 dots.

Conclusion: The purpose of this experiment was to familiarize us with acceleration and the relationship between mass and speed of an item. This is useful because it will tell us how quickly things are moving and how far they can move in each length of time. To do this, we learn how to adjust to various weights and time frames and how to use hz and cm to detect this in little items. Overall, this experiment taught us how to quantify acceleration and demonstrated how a seemingly insignificant detail can have an impact on the study's results.
