Energy

What is renewable energy?

• Renewable energy is energy that comes from non-renewable sources.

• Renewable energy is energy that is harmful to the environment.

• Renewable energy is energy that depletes natural resources.

• Renewable energy is energy that is collected from resources that are naturally replenished on a human timescale.

Name three examples of renewable energy sources.

• Geothermal energy

• Nuclear energy

• Solar energy, Wind energy, Hydropower

• Biomass energy

How is energy transferred from one object to another?

• Through photosynthesis, respiration, and fermentation.

• By telekinesis, telepathy, and teleportation.

• Through mechanisms such as conduction, convection, and radiation.

• Via telekinesis, photosynthesis, and fermentation.

Explain the process of energy transformation.

• Energy transformation is the process of converting matter into energy.

• Energy transformation involves changing the color of light energy.

• Energy transformation involves converting energy from one form to another, such as potential energy to kinetic energy or electrical energy to light energy.

• Energy transformation is the process of converting energy into sound waves.

What are fossil fuels and how are they used as energy sources?

• Fossil fuels are man-made resources created in laboratories.

• Fossil fuels are renewable energy sources that do not harm the environment.

• Fossil fuels are natural resources formed from ancient plants and animals. They are burned to release heat energy for electricity generation, transportation, and heating.

• Fossil fuels are extracted from outer space and brought to Earth for energy use.

What is the difference between potential energy and kinetic energy?

• Potential energy is not related to motion, while kinetic energy is related to motion.

• Potential energy is energy due to motion, while kinetic energy is energy due to position or state.

• Potential energy is only present in moving objects, while kinetic energy is only present in stationary objects.

• Potential energy is energy due to position or state, while kinetic energy is energy due to motion.

How does solar energy work as a renewable energy source?

• Solar energy works by extracting geothermal heat to create electricity.

• Solar energy works by burning fossil fuels to generate electricity.

• Solar energy works by converting sunlight into electricity using solar panels.

• Solar energy works by harnessing wind power to produce electricity.

Describe the concept of energy conservation.

• Energy conservation is the process of creating new energy sources

• Energy conservation involves wasting energy whenever possible

• Energy conservation is only applicable to certain types of energy

• Energy conservation is the principle that energy cannot be created or destroyed, only transformed from one form to another.

What are the advantages of using wind energy?

• Expensive to implement

• Limited availability

• Causes pollution

• Advantages of using wind energy include being renewable, clean, abundant, reducing greenhouse gas emissions, creating jobs, and being cost-effective.

How is energy stored in batteries?

• Energy is stored as gravitational potential energy

• Energy is stored as sound waves

• Chemical reaction converts chemical energy into electrical energy

• Energy is stored as light particles
