kinetic energy

Summary - The essential conditions to be satisfied for work to be done are: Some force must act on the object The point of application of force must move in the direction of force W = F x S SI unit of work is joule Energy is the capacity to do work The two types of mechanical energyh..

Let us see what is actually taking place in the following examples: Steam engine- Here the coal burns and the heat due to the combustion of coal converts water into steam and the expansive force exerted by the steam on the piston of the engine moves the locomotive. Hydroelectric power plant- Here w..

We can see many situations in which energy is transferred to or from objects and systems, similar to money being transferred between accounts. In each situation, we assume that the energy that was involved can be accounted for, that is, energy cannot appear or disappea..

According to this principle, work done by a force in displacing a body, gives the measure of the change in kinetic energy of the body. When a force does some work on a body, the kinetic energy of the body increases by the same amount. Conversely, when an oppo..

Concept of Activation Energy - For a reaction to occur, reactant molecules must collide with each other. Only those collisions result in product formation which have energy equal or more than a certain minimum energy. This energy is called the threshold ..

Summary - The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical ene..

The Electric Potential Energy - The electric potential energy of the alpha particle at the distance of closest approach from the nucleus was found to be equal to Potential energy x charge on a partic..

>In a hydro power plant electricity is produced from water. Hydro power plants convert the potential energy of falling water into electricity. Wind Energy Moving air is called wind Wind possesses kinetic energy Wind energy can be used to sail boats,..
