- A machine is a system that changes the relationship between effort (the force applied) and load (the weight lifted or moved)
- Machines make our lives easier.
- Machines help us to lift,push,pull,turn,cut & join things.
- Wheels, rollers,levers,gears,and pulleys all make it easier to move a heavy load by reducing friction or magnifying forces.
