Solution
Work
Work is the product of a component of a force on an object times the displacement of the object while the force is being exerted in the direction of displacement. Work is a scalar. Work is done on something or by something. Another way of understanding Work is that Work is a change in energy via a force. (There are other ways of changing energy, such a through thermal contact).
The point is that work changes the energy of something and the change is through application of a force. Work can increase or decrease energy. In most classical scenarios, work will change either the kinetic or potential energy.
Work is usually defined as W=F*delta(x) where the * is the dot product.
x is displacement.
Energy
There are many kinds of energy. There are two important things to know.
Energy is the ability to do work. It doesn't mean work is being done, but that work can be done. (So you can see there is an intimate relationship between work and energy).
Energy is conserved. That means the total amount of energy is always constant. If the energy is a system changes somehow, that means some work was done in order to move the energy from one system to another. Difference between Work and Energy 1. Work is the transferring of an energy’s amount via a force through a distance by the direction of the force.
Energy is all defined as the ability to push
or pull by exertion in a certain path or distance.
2. An example of Work: A block displaced along a table by force (F) and distance (D).
Examples of Energy are nuclear energy, solar energy, electrical energy, and a lot more.
