Kinetic energy

An exothermic reaction gives off energy in the form of heat, light or sound and can occur spontaneously. When used in a laboratory exothermic reactions may generate heat or even an explosive. In the other hand, an endothermic reaction absorbs energy and cannot occur spontaneously. When heat is absorbed a temperature drop and is measured throughout the reaction. Endothermic reactions have a…

Energy is the ability to work, more, or elicit change in matter. Energy cannot be formed or impaired; it’s always preserved. Potential energy is a kind of spared energy that objects have because of their position or configuration. Energy comes in many forms, and can be converted from one form to another. Kinetic energy is energy of mass in motion, and the formula is E=1/2mv^2. The most important property of kinetic energy in the ability to do work, and it can be transferred from one body to…

The Egg-Drop Device Process The process of dropping an egg is more complex than a normal person would believe. The egg-dropping process requires knowledge of history, engineering, and mathematics and physics. To fully understand how an egg drops, the knowledge of the history of physics, the engineering behind a device, and the mathematics and physics of free-fall is needed. Physics originates in its classical form in Ancient Greece. Thales was the first physicist. The theories Thales made gave…

Introduction: Every company wants to improve the quality of their product which in turn will increase the market potential of their product. Food companies are also among those companies those have always tried to develop new ways to provide fresh and healthy foods to their customers. In this process, they have to face some difficulties. These difficulties usually happen in the sorting phase of foods. Everyone knows after the passage of time, every food item loses its freshness. As a result, it…

Madame Chill Gloria E. Myers was born on September 23, 1992 in Tampa Bay, Florida. Her parents are Thomas and Linda Jarrell, both came from wealthy families. Growing up in a rich household Gloria had almost everything. The only thing she missed the most were her parents they were always gone her mother always had “business” trips and her father was hidden away in the basement working on his science project. Gloria didn’t have many friends but she did have a nanny named Eli Nora who was always…

trial temperature was closest to internal body temperature, 38℃, and as catalase is present in all body organs (T. Fouad, Antioxidants). Temperature affects chemical reactions by increasing the kinetic motion of molecules and changing the rate of collisions between them. In lower temperatures, kinetic motion is decreased and there are not enough collisions between the molecules for enzyme activity to be maximized. However, as temperature reaches above 40℃, the excessive motion of the enzyme…

1. C Why: according to Newton’s first law of motion, an object that is free from all outside forces travels at a constant velocity, covering equal distances in equal times along a straight-line path, C is true. 2. D Why: not matter an object is still or is in motion, the object has inertia all the time. Inertia is a nature/property of any objects. 3. D Why: the ship is moving at a constant speed, which is in a balanced status. For the athlete, it would be likely to do a long jump on ground.…

the conversion of movement into useable energy, in this case to power of the turbines and generate electricity. Motion is affected by displacement (the final difference in position), instantaneous initial velocity and instantaneous final velocity (the rate of change in position), acceleration (the rate of change of velocity) and time. Each of these variables are interrelated as one can be calculated as long as three others are known. Newton’s…

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,…

potential energy, kinetic energy, and mechanical energy. Potential energy is a type of energy an object has because of its position. For example, elastic potential energy of a rubber band depends on how far it is pulled back from rest. The farther it is pulled back, the higher its potential energy. Once the rubber band is let go, the potential energy is then converted into kinetic energy, the energy of movement. The held end of the rubber band snaps to the other end. Mechanical energy is the sum…
