### Difference Between Power and Work

// Nov 23rd, 2011
Power vs Work   Power and work are two very important concepts discussed in mechanics. Power describes the rate of energy transfer. Work describes the amount of energy transferred. Both of these concepts are very important in fields such as engineering, physics, thermodynamics and even human biology. In this...

### Difference Between Enthalpy and Internal Energy

// Sep 26th, 2011
Enthalpy vs Internal Energy For the study purposes in chemistry, we divide the universe into two as a system and surrounding. At any time, the part we are interested is the system, and the rest is surrounding. Enthalpy and internal energy are two concepts related to the first law of thermodynamics, and they describe...

### Difference Between Newton and Joule

// Sep 24th, 2011
Newton vs Joule Joule and Newton are two units, which are widely used in the SI system. These units are extremely important, and a sound understanding in them is required. Read on to know, what Newton is, what Joule is, what are their definitions and finally the differences between Newton and Joule. What is Newton? To...

### Difference Between Energy and Force

// Sep 17th, 2011
Energy vs Force Force and energy are two fundamental concepts in both classical and relativistic mechanics. It is important to have a clear interpretation of these terms in order to excel in such fields. This article we will discuss the basics of the two concepts, force and energy, their similarities and finally...

### Difference Between Force and Momentum

// Aug 25th, 2011
Force vs Momentum Force and momentum are two concepts that are used in mechanics to describe statics or dynamics of bodies. Force and momentum are among the foundation and basic concepts involved in physics. It is vital to have a good understanding of both force and momentum in order to excel in any field even remotely...

### Difference Between Work and Heat

// Aug 3rd, 2011
Work vs Heat Work and heat are the two most important concepts of thermodynamics. Work and heat are highly interrelated, but they are not quite the same. The quest to understand work and heat goes way back. With these two concepts cleared, classical thermodynamics became one of the “completed” fields in physics....

### Difference Between Enthalpy and Heat

// Jul 28th, 2011
Enthalpy vs Heat For the study purposes in chemistry, we divide the universe into two; as a system and surrounding. At any time, the part we are interested is the system, and the rest is surrounding. Heat and enthalpy are two terms describing the energy flow and properties of a system. Heat The capacity of a system...

### Difference Between Workdone and Energy

// Jul 2nd, 2011
Workdone vs Energy When you hit a golf ball with a golf club, you exert force on the club which in turn exerts force on the ball. So the energy of the golfer is transferred into energy in the club and finally into energy in the ball. We all know that the energy can neither be created nor destroyed and the total...

### Difference Between Task and Activity

// Jun 13th, 2011
Task vs Activity Task and Activity are two words that are often confused due to the appearing similarity in their meanings. Actually they are two different words that give two different meanings. The word ‘task’ refers to ‘work’ or ‘a piece of work to be done or undertaken’. On the other hand the...

On the other hand the word ‘job’ refers to an occupation for which you are paid a salary. This is the main...

### Difference Between Power and Torque

// Feb 11th, 2011
Power vs Torque Torque and power are two terms commonly misunderstood even by engineers, leave alone common people. Both terms describe the ability of a device to do work, but whereas torque is the twisting force applied to an object, power is the application of work within a finite time. Power of an engine is...
