simple machine - a basic mechanical device used to make work easier by changing the direction or magnitude (size/strength) of a force., input force / effort - the force used to operate a machine (the force you apply to the machine to do the work)., output force / load - the force that a machine creates (to move a load) (the force the machine applies on another object)., mechanical advantage - a measure of how many times easier a task is made when using a simple machine., force advantage - applies a small input force producing a large output force., distance advantage - applies a large input force over a small distance to produce a small output force over a large distance., speed advantage - applies a large input force over a small distance (low speed) to produce a small output force over a large distance (high speed).,
