Which statement describes how a machine can help make work easier? It can put out more force than the input force by decreasing the distance over which force is applied.
It can increase the amount of work performed if the output force is in the same direction as the input force.
It can apply a greater output force over a greater distance compared to the input force and distance.
It can increase the distance over which output force acts by applying less output force than input force.
