Simple Machines. Simple Machine - a device that changes the size or direction of a force being used to do work.
What is Matter? Chapter 2 Section 1. Matter What do all of these objects have in common? These objects all have volume and mass. Matter - is anything.
Work and Machines Work – energy transferred when a force makes an object move 2 conditions must apply for there to be work: The object must move Movement.
