 # Aristotle's Theory Of Gravity Essay

Improved Essays
Acceleration, velocity, and gravity are important concepts that each played a role in this lab. Velocity is defined as the speed and direction of motion of a given object. The equation for this particular concept is: v=d/t which states that velocity equals displacement in respect to time. Acceleration is defined as how quickly and in what direction velocity changes. The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity, and ∆t represents the time interval. In addition, gravity is the force that attracts a body towards any physical body that has mass.
Galileo Galilei discovered that the distance a standard accelerating object travels is proportional to the square of the
It is a common misconception that a falling object of a greater weight would have a greater rate of acceleration than a falling object of a lesser weight. In fact, Aristotle himself believed that a heavier object would have a greater desire to be in its natural place. But in this case, Aristotle was incorrect. His logic can be disproved using Newton’s first and second laws of motion. Firstly, Newton’s first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an outside force. Nowadays, this law is also often referred to as the Law of Inertia. According to this law, the heavier object would have more inertia. Because it has more inertia, it also has a stronger resistance against changes in its state of motion. This larger amount of inertia offsets the larger amount of weight, so the two objects, although having different weights, would have the same rate of acceleration. In addition, Newton’s second law of motion—also known as the universal law gravitation—states that the acceleration of an object is directly proportional to the magnitude of the net force and inversely proportional to the mass of the object. Greater force on more massive objects is canceled out by the

According to Sir Isaac Newton’s second law, acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed(needed to accelerate the object). Everyone unconsciously knows the second law. Everyone knows that heavier objects require more force to move the same distance as lighter objects. The second law gives us an exact relationship between force, mass, and acceleration. It can be expressed as a mathematician equation, the formula is F=MxA.…

Velocity is the speed of something in a given direction. This is depending on how much force you have and how fast you’re going because of the speed of the song. However, it also depends on the direction. This only applies to marching because you can’t play in a direction but you can move in a direction. You can actually calculate the velocity by using s=d/t and adding a direction. That again is only for movement because you can’t play in a specific…

With the use of this equation he proved that objects that are heavier fall at the same rate towards earth as objects that are lighter because the earth pulls them down with the same force. To put it in perspective a car and a feather would fall at the same universal rate of 9.8m/s^2 even though one is much heavier. Newton also figured out that the moon is held to the earth by the same force that pulls an apple off a tree (Newton's famous story of the apple…

The relationship between acceleration and energy is that they are both related to speed and how it goes up to it. Acceleration is the rate of change in the object's velocity. Energy (kinetic) can be defined as the speed of the object.…

After solving for velocity, one can get the acceleration of the device as it drops from 75 feet. To calculate acceleration, the formula a = v / t, or in other words, acceleration is equal to velocity divided by the elapsed time. Substituting in the values, acceleration roughly equals 4.6259 m/s^2. With the acceleration, the force of the falling object is calculable using the formula f = ma, or force is equal to the mass times the acceleration. When the values are substituted in, the formula determines the force to be 5.3105…

2. Acceleration is dependent on the forces acting upon an object and the mass of the object. Therefore, if the force is increased, the acceleration is increased. And the more mass the object has, the more acceleration decreases. So the resultant force (F) is equal to mass (m) times acceleration (a) (F = ma).…

Such as when an accelerating object is moving in one direction, while being affected by a force in the opposite direction. At the top of the hill there are balanced forces because the forces in all directions are equal and therefore there is no motion. Force is a push or pull acting on an object. In this case one example of force in Candy Land is as you are going down the 100 foot drop there is a force pushing you down the hill. Air resistance is a frictional force, acting in the opposite direction of the moving object. For example, when you are going up a hill, the cart will slow down due to air resistance. Remember the funnel cake mentioned earlier? Well, as you are zooming in a circle around the funnel cake, centripetal acceleration is present. Similar to centripetal force, centripetal acceleration is when there is acceleration toward the center of the circle.…

Thus, leading Newton to come up with the three laws of motion. The first law of motion was the law of inertia. This law states that an object in motion will tend to stay in motion unless acted upon an outside force and an object at rest will remain at rest unless of course, acted upon an outside force. Newton’s second law states that the force of an object is equal to its mass times its acceleration. The third law of motion is the law of interaction. This states that for every action there is an equal and opposite reaction. For every actions force there is an equal force of action in the opposite direction. It took Galileo, Copernicus, and Kepler to prove Aristotle 's theory wrong. On the basis of this, Newton came up with the three laws that play a significant role in the unearthing of the concept of gravitational force but his laws do not completely explain everything necessary to know about gravitational…
