![]() Water and most biological tissues fall into this category. (Another method for simulating anti-gravity uses a “Random Positioning Machine” (RPM).) Some materials-diamagnetic materials-are repelled by a magnetic field. ![]() The method is called diamagnetic levitation. A team of researchers from several European institutions have used magnetism to offset the effects of gravity at the cellular level. There is a way to simulate weightlessness at a small scale in the lab. Therefore, it would be nice to have an anti-gravity machine in our Earth-bound laboratories to run experiments without the cost and scheduling constraints imposed by space flight. If a key step in carrying out an experiment on, say, the response of cells to lack of gravity, is “shoot the experiment into space and keep it there for two months” then it will take a very long time and a lot of money to get results one might need to make sense of low-gravity biology. Anyone who has spent time working in a laboratory knows that many experiments have to be redone numerous times just to get the procedures to work properly. Studying the effects of low gravity in space craft and space stations is expensive. These effects seem to get worse over time, so understanding the effects of gravity on human physiology is essential when planning long-distance space flights. Astronauts return from space with muscle atrophy and reduced bone mass. We’ve known for a long time that humans are harmed by long periods in low-gravity environments. ![]() Of course, gravity is only one factor, and other factors such as adhesion or buoyancy determine whether an organism falls off the ceiling, say, or how long it takes an organism to settle to the ground. One final component of this lab, found within the Discussion section, will be the demonstration of how the application of key concepts within physics can lead to the derivability of any number of equations, which is a very useful aspect of the study of physics.Gravity potentially affects all biological processes on Earth, even though this may be hard to believe while we watch flies walking around on our ceilings as though gravity did not matter to them at all. The effects (if any) of mass on gravitational acceleration are tested by dropping a second sphere, different from the first, and measuring how long it takes to fall. Measuring how long it takes the sphere to fall, it is then possible to calculate gravitational acceleration. This all will be accomplished first by dropping a silver colored metallic sphere from several pre-established heights. The question of whether or not heavier objects fall faster will be answered yet again, determining if Galilco's experiments at the Leaning Tower of Pisa were right. The main objective for this experiment is to calculate the acceleration 7g of a free falling object manifested due to the force of gravity In addition to this objective, this experiment will also determine if mass or the distance that an object falls influence the gravitational acceleration that object experiences. If one were to ask people the first name that pops into their mind when they hear the word "physics", most likely it will be Sir Isaac Newton and his allegorical apple falling from the tree), or Albert Einstein (whose theory of relativity modifies and extends Newton). ![]() In fact, two of the most well koown names in physics found their fame in dealing with gravity. M9c: Free Fall Acceleration Introduction: Gravity represents one of the central concepts of physics. ![]()
