2. Energy and its types
• Energy is defined as the capacity of a body for doing work
• Energy can take a variety of forms:
• Mechanical energy – potential and kinetic energy
• Electrical energy
• Electrical energy can be stored in a capacitor
• Chemical energy
• Both mechanical and electrical energy can be converted into heat
which itself is a form of energy

3. Sources of Energy
Renewable and Non-renewable

4. Sources of Energy
• Renewable
An energy source that can
be replenished in a
short period of time
• Non – Renewable
An energy source that we
cannot replace
