Simple Machine Joemarie A. Martinez 1-D CE Simple machine Simple machines make work easier by multiplying‚ reducing‚ or changing the direction of a force. The scientific formula for work is w = f x d‚ or‚ work is equal to force multiplied by distance. Simple machines cannot change the amount of work done‚ but they can reduce the effort force that is required to do the work! As you can see by this formula‚ if the effort force is reduced‚ distance is increased. These simple machines
