FAQs on Fun Video: Work and Power Video Lecture - Physics for Airmen Group X - Airforce X Y / Indian Navy SSR

 1. What is work in physics?
Ans. Work in physics is defined as the measure of energy transfer that occurs when an object is moved through a distance by an applied force. It is calculated by multiplying the force applied to an object by the distance it is moved in the direction of that force.
 2. How is work related to power?
Ans. Work and power are closely related in physics. Work is the amount of energy transferred, while power is the rate at which work is done. Power is calculated by dividing the amount of work done by the time it takes to do that work. In other words, power measures how quickly work is done.
 3. What are the units of work and power?
Ans. The SI unit of work is the joule (J), which is equivalent to a force of one newton acting over a distance of one meter. The SI unit of power is the watt (W), which is equal to one joule per second.
 4. How can we calculate work when the applied force and displacement are not in the same direction?
Ans. When the applied force and displacement are not in the same direction, we can calculate work by taking the component of the force that is in the same direction as the displacement. This is done by multiplying the magnitude of the force by the cosine of the angle between the force and displacement vectors.
 5. What is the relationship between work, power, and time?
Ans. The relationship between work, power, and time can be expressed as follows: Work = Power x Time. This equation shows that the amount of work done is directly proportional to both the power exerted and the time taken to do the work.
