Types of Energy
Name the type of energy something has when it is moving.
What is Kinetic energy
Where do living plants get their energy?
What is Sun / solar energy
A book sitting on a shelf has what kind of energy?
What is Potential energy
Chemical energy in a battery can become what type of energy in a lightbulb?
What is Light energy through electrical energy
Are wind and water considered renewable or non-renewable?
What is Renewable
Name the type of energy stored in food or batteries.
What is Chemical energy
Name a natural resource that provides energy by moving water.
What is Hydroelectric energy / moving water
A ball rolling down a hill has what kind of energy?
What is Kinetic energy
Mechanical energy can be changed into what two other types of energy?
What is Heat (thermal) and sound
What is one advantage of using wind or water to produce electricity?
What is They do not pollute the environment / they are renewable
What kind of energy travels as waves and lets us see things?
What is Light Energy
Give one example of a fossil fuel.
What is Coal (also oil or natural gas)
Explain briefly: How does potential energy relate to kinetic energy when an object falls?
What is Stored potential energy becomes kinetic energy as it moves
Name the energy conversions when wind turns a turbine to make electricity.
What are Kinetic (wind) → mechanical (turbine) → electrical)
What is one negative effect of using coal to produce energy?
What is Coal produces pollution and harms the environment ( acid rain, smog, destroys animal habitats)
What type of energy do we feel as warmth?
What is Heat or thermal energy
Why are non-renewable resources considered valuable?
What is They take millions of years to form
If a toy car is pushed harder, what happens to its kinetic energy?
What is It increases — the car goes faster and travels farther
Give an example of chemical energy changing to mechanical energy in everyday life.
What is Fuel in a car (chemical) → motion of car (mechanical)
What is one negative effect of wind turbines on wildlife?
What is They can injure birds and other flying creatures
What type of energy does a stretched rubber band have?
What is Elastic potential energy / potential energy
Name three natural resources that can provide energy.
What are Sun (solar), wind, water (hydroelectric); fossil fuels like coal)
The more potential energy an object has, the greater its ______ energy will be when released.
What is Kinetic
Describe, in one sentence, how electrical energy from a battery can produce light and heat.
What is The battery's chemical energy becomes electrical energy; the electrical current powers the bulb, producing light and heat
Explain why some energy sources are called renewable while others are non-renewable.
What is Renewable sources do not run out on human timescales (sun, wind, water); non-renewable sources take millions of years to form and can be used up (fossil fuels)
