You push against the back of your friends car that is stuck. You push and be become very tired, but the car does not move. Did you do work?
Yes, work was done
No, work wasn't done
If Jesse studies for hours, did he do any work?
Yes
No
In science, for “work” to be performed, a force must be used to move an object. Regardless of how much force is being used, if no movement occurs, no work is done.
For work to be done, according to physics, which of the following are true?
A force must be applied to an object.
The object must move a certain distance.
The object must move in the same direction as the applied force.
It takes energy to do work. And, if you do work on an object you give it energy.
