what is the formula for work? | work = force x displacement |
what is the capacity to do work? | energy |
what is internal work? | if a part of a system exerts a force on another part of the same system and motion in the direction of the force occurs |
what is external work? | a system as a whole exerts force on its surroundings and a motion in direction of force occurs |
what is the work-energy theorem? | formula showing work done on rigid body by net force changes energy of the body; work done by all forces acting on a particle (the work of the resultant force) |
what is joule? | a unit of work equal to one newton-meter |
what is scalar? | work is a (scalar/vector) quantity because it depends on the net distance involved, regardless of the direction |
