The purpose of this experiment was to understand kinetic and potential energy and verify the Law of Conservation of Energy. Kinetic and potential energy are both forms of energy that usually coincide with each other; potential energy usually changes into kinetic energy and vice versa. While potential energy results from an object’s position or arrangement of parts, kinetic energy results from an object’s motion. Together, the sum of an object’s kinetic energy and the potential energy at that instant is its total mechanical energy, which is given as: ME = PE + KE. In order to verify that the total mechanical energy if the system is conserved, the change in the mechanical energy of the system have to be zero. Two experiments were performed with different set-ups to test if energy was conserved in each system. In the first experiment, a projectile launcher was used to launch the object, a ball, vertically upwards. The computer program, LoggerPro, will determine the initial velocity of the ball. If the starting point is the point where the ball is launched, then the potential energy is equal to zero and thus, the initial kinetic energy would then be KEi = (1/2) mvi2. When the ball reaches its highest point, its final speed at the highest point is zero and the total mechanical energy at the highest point will be PE=mgh, where g is the gravitational force. Similarly in the second experiment, the air track will caused the glider move down the track and LoggerPro will obtain its…

Energy Thermodynamics is, the everything that happens due to the flowing of the heat from a hot locale to a cold locale, and nothing occurs without the flow of the heat. Additionally, thermodynamics is an exact science. Thermodynamic system is defined by volume, pressure, temperature and chemical make-up. When conditions change the thermodynamic system will respond by changing its temperature, volume, pressure, or chemical make-up and will adjust accordingly in order to reach its original state…

observe adherence to the conservation law. The conservation law states that should be equal to zero, and as this wasn’t observed in any trial, it can be said that the conservation law was ineffective in this system. This is also replicated in the loss of kinetic energy. Kinetic energy is being lost in the form of sound as the collision takes place. However, kinetic energy is a scalar quantity, therefore the difference between the initial kinetic energy and the final kinetic energy is the actual value…

all three of Newton’s laws and the associated ideas of collisions, momentum, energy, forces, and friction. There are two fundamental laws used in this game that are very important. First, the law of conservation of energy states that in an isolated system, the total energy remains constant. This game uses mechanical energy specifically, and also the conservation of energy in an elastic collision. If there are no external forces acting upon the system, the amount of total energy present before the collision…

Energy is a property of objects that can be converted in plenty of different forms or be transferred to another objects. Energy comes in these different forms that may seem different, but they all amount to the same thing. Energy is one of the true constants of universe because as long as the universe has been existent, energy was existent. Due to it being a true constant energy can never be created or destroyed, this is called the law of conservation of energy. This law states that the total energy…
