Unit Award Scheme

demonstrated the ability to

1. describe how at least two simple machines, eg ramps, pulleys reduce the force needed to move objects by using the key terminology such as force, distance and work

2. construct a working simple machine to measure how altering a key variable, eg changing the ramp gradient, adding extra pulley wheels, affects the force required to move an object

3. describe how their simple machine works using the key physics terminology, eg force, work, mechanical advantage

4. describe how at least two forces such as friction and air resistance hinder the efficiency of a simple machine.
