The work and energy are closely associated terms in physics due to which it sometimes get hard to differentiate between them. The work is the process in which energy transfer takes place, and the objects travel in the direction of the force applied. On the other hand, energy is the ability of the body through which one can do the work. Moreover, the energy can neither be created nor be destroyed. The work is the compact process in the field of physics under which the energy conversion takes place, and the energy applied to the object leads the work done after it travels in the direction of the energy applied.

Energy is the strength needed to perform work, while the rate at which work is performed is called power. The unit of measurement in energy is termed as joules, whereas, a watt is the measurement unit of power. As in our day to day life, work entails the physical and mental strain, such as dancing, singing, cooking, bathing washing, learning, etc. However, in science work implies the outcome of force acted upon an object, to cause or stop-motion, which is measured in terms of joules. Energy and power are the two fundamental concepts related to work, which is used as the synonym, but they are not one and the same thing. Basis for Comparison Energy Power Meaning Energy is described as the object's ability to perform work. Power alludes to the rate at which work is performed upon an object.

If one object transfers gives energy to a second object, then the first object does work on the second object.

Energy is like a commodity; an economic analogy would be like money in your bank account. You can convert one form of energy into another. In the economic model you can covert rupees into an equivalent amount of dollars or you can withdraw from the bank account and put the cash in your pocket. The total amounts of energy and economic values remain the same. Work on the other hand is a specific form of energy transfer, one due to large-scale motions along the direction of an applied force. Work can either change the kinetic energy e. Follow-up on this answer.

Physics is not a subject most of us are comfortable with. As a subject during high school and as a subject during college, we often scratch our heads and wonder why we should study this subject. From computing the distance up to measuring velocity, we often wonder if we can use this as ordinary citizens of the world. If riding in a car while computing the acceleration will help us get ahead, even the unsurprising traffic is in sight. But in physics, these two words do not come easy as it is. It is a broad concept in which a lot of explanations can be derived. He is a French mathematician.
