Energy, work, Power
The process of transferring energy from one form to another is called work. In badminton, work is done in many different ways. For example, you are lifting the racquet to hit the shuttlecock or you are running to retrieve it. Assume that you are lifting a badminton racquet vertically at a force of 20.0 N for a distance of 2.0 m. How much work is done? To calculate this question, you must use the formula W= Fapp* Δd where ‘W’ represents work done, ‘Fapp’ is force applied, and‘d’ is distance. 
The confusion of work and power is much anticipated but they are two different things. Work is the amount of energy that is transferred while power is the rate or speed in which the energy is transferred at. Power can be modeled by the equation: P= W/ Δt, where 'P' is the power, 'W' is work and 't' is time. Assume that a shuttlecock is smashed with 1600 J of work in 4.0 seconds. What is the power?
