Pg.3-6 Conclusion…………………………………………………………………………….………………… Pg.6 Bibliography………………………………………………………………………….………………… Pg.7 Claim All objects regardless of their mass, fall to the ground at the same rate. Rationale This claim states that all bodies with varying masses fall towards the ground at an equal rate (9.81 ms-2.) For centuries, this topic has been debated, with famous scientists Newton and Galileo supporting …show more content…

All objects are pulled towards earth at a constant rate of 9.81 m/s2, this is called gravitational pull. If a heavy object and a light object is held in either hands, it would seem the heavier object would fall faster. Bodies with a greater mass require more force to be pulled towards the earth with the same acceleration. Objects with a greater gravitational force require more force directed in the opposite direction to keep it balanced. Equations can be used to prove this claim. For this example, an object that weighs 10 kg and an object that weighs 100 kg can be used. To calculate the acceleration of these two objects, we can use Newton’s second law of motion. The equation given in Newton’s second law is: F = ma To find acceleration, the equation must be re arranged: a = F/m Because all objects fall to the ground at 9.81m/s2, it can be substituted for the acceleration: F = m * 9.81 9.81 = …show more content…

As expected, the bowling ball hits the ground first, while the feathers take a significantly longer time to hit the ground. Then they repeat the experiment but lower the pressure immensely to form a vacuum. It was discovered that the bowling and the feathers fell to the ground at the same rate, proving that mass does not affect an objects acceleration, if air resistance is not present. Figure 1: An image taken from the inside of a vacuum chamber by BBC Two at the Space Power Facility, Ohio. The amount of air resistance something encounters depends on two factors, size and mass. Objects with a greater surface area will encounter more air resistance as there is more space for air molecules to collide. As for mass, objects with a greater mass will take longer to reach terminal velocity. Heavier objects also exhibit a greater gravitational force, meaning that it will take longer to reach terminal velocity. An experiment conducted by the State University of New York College of Environmental Science and Forestry (SUNY ESF) compares the time it takes for objects of varied sizes and masses to hit the ground when dropped from the window of a building. The results recorded are given

The acceleration for each mass varies in number but are fairly close to each other as seen in table one. Table 2 displays the average acceleration and deviation of each mass. Figures two and three give sample position and velocity time graphs of each mass. Figure four displays the error margins for each mass. From the graph you can conclude that acceleration is not constant because a straight line cannot be drawn between each error margin.

In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.

This means that the slope is going to be an upward positive slope. Since Fg=m*g, and acceleration due to gravity (g) (9.8m/s^2), the more mass there is the more weight there will

The pennies, however, would be slowed down by air resistance and would not gain any more speed. For example, in a significant article regarding how pennies fall, it states, “The pennies ‘reach terminal velocity and no matter how high we put the balloon, they never picked up any more speed’” (Stossel, Binkley 2). This was derived from a test where pennies were dropped by a balloon from hundreds of feet high and proved that no matter where the balloon was, the pennies didn’t pick up any more speed. Terminal velocity is the maximum speed a falling object reaches and is determined by the object's weight and air resistance (Stossel, Binkley 2).

In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.

Henry Cavendish was a British philosopher who was known for being very accurate in the experiments he conducted, such as the composition of atmospheric air, electrical attraction and repulsion, and calculations of the density of the Earth. Cavendish contributed to the universal law of gravitation whenever he developed the constant of “G” in his primary experiment, and he placed this constant G in Isaac Newton’s Law of Gravity, adding onto it. In Cavendish’s famous experiment, also known as the torsion balance, to find “G”, he hung a dumbbell from a string, placed two large weights below the dumbbell, saw that the string was twisting and was able to measure the force between the objects. After measuring the force, Cavendish documented the measurements

After the experimentation, you may ask yourself “Why did all of these spheres fall at a different rate when Galileo said that objects fall at the same rate (in a vacuum)?” The reason why the objects fell at a different rate in the fluids given was because the fluid’s viscosity varies. The viscosity of a fluid can impact an object that you drop into it, because there’s a resistance of some sort impacting the rate of which they fall. For example, when both spheres were dropped at the same time into a graduated cylinder of water, the steel sphere hit the bottom of the graduated cylinder before the glass sphere, because the viscosity of water is low. The viscosity of water is very dynamic based on the temperature, but both of the spheres were denser

As the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object.

How Gravity Works Gravity pulls objects down towards the ground due to the force of attraction that the earth has, and the way it works on different places or different planets. To start it off, gravity is able to keep objects from floating out into space and down towards the ground because of the gravitational pull that surrounds the world. The reason that gravity works like that is because it is around the world and it has a stronger pull than the gravity on other planets, that's why it seems like there is no gravity on other planets. The gravitational pull is something that covers the world and keeps objects from floating out into space. The gravitational pull provides gravity to keep mass, and matter from going out into space and floating

Newton’s laws state that every action has an equal and opposite reaction, so when the apple falls from the tree it causes a force on earth equal to its weight (F=mg). If you then drop a hammer on earth it will also cause a force equal to its weight (F=mg). These two examples show how gravity can be explained using Newton’s laws of motion. The hammer does not hit you because there is no reaction force acting on your hand, but because there is no reaction force acting on your hand it acts as if you were hit by the hammer.

Today virtually every child grows up learning that the Earth orbits the Sun, but four centuries ago the heliocentric solar system, where the Earth orbits the Sun, was so controversial that the Catholic Church classified it as a crime of heresy (UCLA). In the age of early philosophy, Socrates’ is well known. Between the Socratic method and his line of successful students, Socrates’ makes the history books. Galileo Galilei turned astronomers on their heads when he discovered moons around Jupiter. Giordano Bruno didn’t back down from any of his brilliant and different ideas.

Mickey Ngobeni Research Question: Is the movie ‘Gravity’, according to Newton’s laws and physics in general, accurate? Introduction: ‘Gravity’ is a sci-fi, techno-thriller movie that has its plot’s setting based in space. Astronauts (main characters: Sandra Bullock as ‘Dr. Ryan Stone’ and George Clooney as ‘Matt Kolwaski’) are sent into space, yet encounter a series of events, most of which is susceptible to occur in outer space (Foogray, 2015). Questions have risen as to how accurate the movie is according to physics and Newton’s law, and many have been answered.

These days Sir Isaac Newton is known as "the most influential scientist of modern physics", he is most recognized in two words apples and gravity yes he have more achievements but his more important and influential one was the gravity that he discovers while he was sleeping at the feet of a tree and an apple fall down and punch his head and with that "accident" he developed three laws of motion, he was a physicist and mathematician also he was knighted by Queen Anne of England, making him Sir Isaac Newton. What is more interesting there are conspiracies or theories that say that the falling apple is a myth, do theories say that the apple doesn't really fall on his head there are bot proofs of that yeah is a fact that the apple really fall straight down but there are complications that say that it doesn't fall on his head, that make us think that he sees the apple fall to the ground and that could inspire him to explore the theory of motion and gravity.
