Need help on work-energy principle!
How do work relate to energy?
If a car which have kinetic energy of 10,000 Joules. A collide with a wall but the wall doesn't move so does the car do the work on the wall? But in the the book they state that energy spend = workdone.
only the wall that do work on the car in this case because the car chasee would collide backward
please help i am really confuse, i am grade 9 student
