- P1.2 Using energy
- Forms of energy
- Chemical energy
- stored
- released through chemical reactions
- Kinetic energy
- energy from a moving object
- Gravitational potential
- energy due to the position
- Elastic potential
- Stored in a springy object
- electrical
- transferred by an electric current
- Chemical energy
- conservation of energy
- energy cannot be created or destroyed
- useful energy
- energy transferred to where it is wanted
- wasted energy
- energy not usefully transferred
- energy and efficiency
- weight
- Newtons (N)
- Energy
- Joules (J)
- efficiency
- useful energy / total energy (x100)
- more efficient by reducing
- friction
- air resistance
- electrical resistance
- noise
- weight
- input energy
- useful energy + energy wasted
- Forms of energy
