Question

How do simple machines make work easier? A. They add energy to the work. B. They change the strength or direction of a force. C. They reduce the speed of work. D. They increase the distance of applied forces.

Answer 1

your answer should be B

Answer 2

Out of the choices provided I would choose B, this is because A is wrong due to simple machines making our work easier and require less energy, C is wrong due to the work actually being done faster due to simple machines. Now D and B felt like they were both correct but  D just doesn't make much since when you apply it to the topic of Simple machines so I found B.
