## Acceleration Due to Gravity & Velocity of an Object in Free Fall Lab Answers

If the velocity and time for a free-falling object being dropped from a position of rest were tabulated, then one would note the following pattern. Villanueva Performed 9 September 2015; submitted 16 September 2015 Abstract-Limit the abstract to four to five sentences stating the following: a statement of the problem, b methodology, c pertinent results, and d conclusion. An object in the technical sense of free fall may not necessarily be falling down in the usual sense of the term. I measured and recorded the displacements corresponding to the 6 dot intervals in table 1. You end up with a table of data giving distances.

## Introduction to Free Fall

Therefore, the data collected was very accurate. This time throw it horizontally and notice how its horizontal velocity gradually becomes more and more vertical. I would measure the time it took them to fall form a balcony to the ground. Astronaut David Scott released a rock hammer and a falcon feather at the same time during the Apollo 15 lunar mission in 1971. As I said earlier, this concept will be discussed more thoroughly in a of this book. When this happens, an object may be falling, but it is not in free fall. Gee, Wally As was discussed earlier, don't confuse the phenomena of acceleration due to gravity with the unit of the same name.

## Acceleration of Gravity

Well it all has to do with acceleration due to gravity. Include: a the names and lab duties of each of the participants, and short abstract b the organized data tables for all experiments c the graphs you drew, and the calculations of the slope of the velocity vs. We found that our experimental values differed from the accepted value for gravity by less than ten percent, which can be attributed to experimental error. Free fall occurs whenever an object is acted upon by gravity alone. Furthermore, even on the Earth, this value varies with latitude and altitude to be discussed in later chapters. Due to change in velocity, there was a change in displacement.

In a tale that may be apocryphal, Galileo or an assistant, more likely dropped two objects of unequal mass from the Leaning Tower of Pisa. With careful handling, this can support at least a kilogram weight. Hold the top of the Picket Fence and drop it through the Photogate, releasing it from your grasp completely before it enters the Photogate. We used this software to determine average velocity and instantaneous velocity. The fluid is known as hydrostatic fluid. While the quantity g has a value that depends on location and is approximately 9.

Time graph, the gradient of which should equal the constant force acceleration due to of gravity. The acceleration due to gravity is effectively 9. Performing this experiment, you will become more familiar with the effects of gravity-you find the acceleration of bodies in free fall yourself and you will learn more about gravity in later chapters. There are also local variations that depend upon geology. We determined many solutions using video analysis.

## The Free Fall Experiment

Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. . For most applications, the value of 9. That is why the astronauts were able to hop around on the surface easily despite the weight of their space suits. To establish the reliability of your slope measurement, repeat Steps 2 and 3 at least five more times.

Physics Free Fall Lab By: Jordan Martin, Qusay Multani, Erika Lipford, and Allison O'Brien The purpose of this lab is to find the gravitational acceleration of the objects falling freely and to prove that it is the same with any type of object Purpose We are using the following: 1. And the velocity time graph will be a straight line. Use the Gravitational Fields widget below to investigate how location affects the value of g. Acceleration is the rate at which an object changes its velocity. Instead of seeing a stream of water free-falling from the medicine dropper, several consecutive drops with increasing separation distance are seen.

The two quantities are independent of one another. Record the slope in the data table below. The values of a a gt 2 should all be equal within the accuracy of your measurements. Be careful when releasing the Picket Fence. That is, heavy objects fall fast and light objects fall slow. Together, they should have twice their original acceleration. Reinforce the tape by doubling a strip of masking tape over one end and punch a hole in the reinforcement one centimeter from the end.
