In what ways is the word "work" as used in everyday language the same as it is defined in physics? In what ways is it different? Give examples of both.

In physics we say that the force is doing the work if, when acting, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement).
In everyday life work is said to be done every time there is some effort included. For example if you are pushing against the wall, in everyday language it is said that you did some work, but in physics unless you have moved an object, you did not do any work according to the definition above. So in physics work is this part of work from everyday language that moves an object in the direction of the force.
The word “work” is similar to the one defined in physics, because it just about includes every physical activity that we do and observe in our day-to-day life. Example: Swimming, walking, writing etc are analogous to the fact that a force displacing a body is said to have done work.
