Answer 1

work :- When a force act on a body or object, it causes the object to move to cover a distance. Furthermore, sometimes it happens that the direction of the moving object is not as same as the direction of the force. Moreover, in these cases the component of force that acts in the direction of the movement causes work to be done.

work formula

In simple words, work refers to the force you apply to an object to cause a change in its position or when the object moves and cover some distance. Besides, the S.I unit of work is Joules (J). Most noteworthy, joule and newton-meter (N) is the same thing. In this way, the unit for work and energy is the same.

Transfer of Energy

When we do work we transfer energy from one object to another. Also, work links with expansion and contraction of gases. Moreover, when gas tries to expand it exerts an increasing force on the surface of the container and might make that surface move.

For example, suppose you heat a balloon then the air molecule inside the balloon will gain energy and strike each other. Also, this will cause the molecule to hit the surface of the balloon with more force causing its surface to expand. In this way, the air does work and transfer energy to the balloon.

Answer 2

Answer:

work is something which can be defined when a force produces motion.

for example:-

• a horse pulling a cart.
• when engine of train pulls the boxes.
• when you move a substance.

etc.
