Unit and Examples of Work
The SI unit of work is Joule (J). For example, if a force of 5 newtons is applied to an object and moves 2 meters, the work done will be 10 newton-meter or 10 Joule. It should be noted that 1 J = 1 N ⋅ m = 1 kg ⋅ m2/s2. Example of Work…

Formula of Work
The work done by a force is defined to be the product of component of the force in the direction of the displacement and the magnitude of this displacement. W = (F cos θ )d = F.d We understand from the work equation that if there is no displacement, there is no work done, irrespective…

What is Work?
What is Work? For work to be done, a force must be exerted and there must be motion or displacement in the direction of the force. The work done by a force acting on an object is equal to the magnitude of the force multiplied by the distance moved in the direction of the force.…

Examples Of Motion
Now let us understand motion clearly with the help of a few examples. Our daily activities, like walking, running, closing the door, etc. involve motion. There is a change of position of the object involved in these activities. The flow of air in and out of our lungs is also an example of motion. The…

Types Of Motion
We might have noticed that different objects move differently. Some objects move in a curved path, some in a straight path and a few others in a different way. According to the nature of the movement, motion is classified into three types as follows: Linear Motion Rotary Motion Oscillatory Motion Linear Motion In linear motion,…

What is Motion?
We can define motion as the change of position of an object with respect to time. A book falling off a table, water flowing from the tap, rattling windows, etc all exhibit motion. Even the air that we breathe exhibits motion! Everything in the universe moves. We live in a universe that is in continual…

Introduction
When we talk about motion or rest it is with reference to some point known as the origin. So, now with respect to the change in the position we have two quantities which can be used to describe that change in position. They are distance and displacement. So now the question is, what is the…
