    Chemistry is a subdiscipline of science that deals with the study of matter and the substances that constitute it. It also deals with the properties of these substances and the reactions undergone by them to form new substances. Chemistry primarily focuses on atoms, ions, and molecules which, in turn, make up elements and compounds. These…

    Power is a physical concept with several different meanings, depending on the context and the available information. We can define power as the rate of doing work, and it is the amount of energy consumed per unit of time. Formula of Power As discussed, power is the rate of doing work. Therefore, it can be…

    Energy is the ability to perform work. Energy can neither be created nor destroyed, and it can only be transformed from one form to another. The unit of Energy is the same as of Work, i.e. Joules. Energy is found in many things, and thus there are different types of energy. All forms of energy…

    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…

    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? 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.…

    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…

    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,…
