Which of the following is the best definition of work?
Work=Force x Distance
Power is the amount of work that is done.
Work and Time
Moving pulleys are attached to the object and move with the object. Fixed-position pulleys are connected to a fixed point and
Simple machines keep the work the same but make the work easier
Same amount of work in less time
Work occurs when a force acts on an object and it causes displacement of that object
Multiply the input Force
What is power the quotient of?
Work=Force x Distance
Power is the amount of work that is done.
