What Do You Remember<br />
1. When using a can opener, what input force is<br />
involved What is the output force K/U<br />
2. Different types of physical systems are named<br />
for they type of energy they use. Give an<br />
example of each type of system and state the<br />
type of energy they use.<br />
(a) mechanical system<br />
(b) optical system<br />
(c) electrical system K/U<br />
3. Identify two components of the following<br />
systems:<br />
(a) the circulatory system<br />
(b) a can opener<br />
4. Social factors can influence the evolution of<br />
a system. For example, when more women<br />
joined the work force, the need for quality<br />
child care rose.<br />
(a) Name two systems, and for each one list<br />
two social factors that have caused those<br />

10. You can make an electromagnet by wrapping<br />
a coil of wire around a nail (Figure 2), and<br />
then passing electricity through the wire.<br />
Identify four components of this system and<br />
tell the function of each. K/U A<br />
