## Picket Fence Free Fall

Thus, falling through an atmosphere without a deployed parachute, or lifting device, is also often referred to as free fall. The experiment also discusses different properties of light rays. To find our average we took 9. Throwing the picket fence downward would change the velocity and time, but not the acceleration due to gravity. Data Tables: Data Table 1: Food Item - Observations. Acceleration, Classical mechanics, Force 651 Words 4 Pages Physics Lab Report: Parallel Force Aim: To test the principle of moments.

Discussion of Principles In this experiment you will measure, with the aid of computer-based instruments, the position of a falling body as a function of the time elapsed since it was released. G can't vary greatly at different locations, but the difference can be slight. When performing a quadratic fit of a Distance vs. At the north pole end, the compass would point down into the earth. Purpose of Experiment: The purpose of this experiment of to measure the velocity and acceleration due to gravity of a picket fence and to verify the acceleration due to gravity using the picket fence with Logger Pro and Photogate.

Free Fall Lab Natalie Soria Lab Partners: Ryan Michaely Iqra Haji Yan Huang 1. This was a helpful lab that was very interesting. Extinction of species was previously thought to be caused by natural events, such as asteroid strikes, climate shifts and volcanic eruptions. The A value for this graph is 4. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature ΔT , its mass m , and an intrinsic characteristic of the material forming the body called specific heat cp. This number should have been 4. We were given formulas to solve the problems.

The percent error between the average acceleration in the six runs and the accepted value for gravity was only 1. Theory Everything , regardless of mass, fall with the same acceleration due to gravity assuming that there is no air resistance. The expected A value would be 4. A second objective of this experiment was to learn how the specialized equipment such as the photogate and the picket fence worked. Adding air resistance would change the results. While the picket fence is passing through, the photogate will measure the time it takes for the leading edges of two black bars to block the beam. The sign for the acceleration when the picket fence was thrown upward is negative, not positive like the first seven runs, because the fence was going in the opposite direction.

Method Used: 1 Place the steel ball on the drop box. Complete four more trials of this experiment so that you have saved a total of five data runs. Autoscale and examine your graphs. The acceleration when thrown downwards run 7 is 9. The entire length of the Picket Fence must be able to fall freely through the Photogate.

The materials that we would need for this activity are a lab cart on a flat track, a timer. This created the possibility for the tape to be released slightly before or after the timer was activated. After we got everything set up we started our trials. You drop a small steel ball from various heights and use an electronic timer to measure how long it takes the ball to hit the ground. Any lab report should have the following features:. For this reason, you are required to thoroughly read through the experiment information presented in the lab manual, and complete a pre- lab for each experiment you do.

Free- Fall Lab Assignment Nishad Gothoskar Physics Online Experimental Design: In order to design an experiment to measure free- fall acceleration, the researcher must construct a wooden tower with height 10 meters along with a trap door system to release a tennis ball from rest position. The control variable is the mass of the pendulum. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. One or both surface usually has a spherical curve. This was a fun lab over all. Collect a seventh data run where the Picket Fence is gently thrown downwards through the Photogate, instead of being dropped. Today the greatest risk to species extinction are human activities.

The drop times between the two different sized balls are very similar. Dropping the picket fence from higher above would change the time, and velocity, but it wont change the acceleration. During this experiment, you will drop an object called a picket fence; this is a sheet of clear plastic with equally spaced black bars on it. In a uniform gravitational field, in the absence of any other forces, gravitation acts on each part of the body equally and this is weightlessness, a condition that also occurs when the gravitational field is zero such as when far away from any gravitating body. The parabolic shape of the graph shows that the picket fence had a constant acceleration as it fell. There are many ways to do this. To simulate projectile motion, a ball was tossed in the air and analyzed using video software.

Theory: All objects, regardless of mass, fall with the same acceleration due to gravity assuming that there is no air resistance. Our average number was 9. You will drop a piece of clear plastic with evenly spaced black bars on it, called a Picket Fence. Any differing results can be attributed to human error of timing as well as to air resistance minimal. Time graphs for your first five stored data runs? In this lab our goal was to see if we can prove if the acceleration due to gravity is 9. This proves that none of these circumstances had any effect on the acceleration of the fence and that only gravity influenced its fall.
