Lesson Worksheet: Conservation of Energy Science
In this worksheet, we will practice describing the law of conservation of energy using energy chains.
The law of conservation of energy states that energy can from one form to another.
- Abe created
- Bnever be transformed
- Cbe transformed
- Dnever be transferred
True or False: In some energy chains, some of the energy is wasted in the form of thermal energy.
True or False: The mobile phone converts chemical energy stored in its batteries into sound and light energy, and it produces thermal energy as waste energy.
What is the scientific term for the change of energy from one form to another?
- AEnergy conservation
- BEnergy transformation
- CEnergy efficiency
- DTransfer of energy
The energy chain of burning wood starts with solar energy transformed into chemical energy that is stored and then transformed into heat and light. This energy chain proves the law of .
- Agravitational force
- Bconservation of energy
- Cefficiency of energy
- Dforce and motion
