Energy Basics and Forms
The scientific definition of energy.
What is the ability to do work or cause change?
This famous scientific rule states that energy cannot be created or destroyed, only changed.
What is the Law of Conservation of Energy?
Thermal energy always moves in a predictable path from this type of object to a cold object.
What is a hot object?
This general term describes energy resources that cannot be replaced once they are used up.
What are nonrenewable energy sources?
This vocabulary term means using less energy to complete the same everyday tasks.
What is conserving energy
This form of energy travels in waves and can move through empty space, like light from the sun.
What is radiant energy?
When plants use photosynthesis to make food from sunlight, radiant energy transforms into this form of energy.
What is chemical energy?
Your hand feels cold when holding an ice cube because heat is moving in this direction.
What is from your hand into the ice cube?
Coal, oil, and natural gas are group together under this category of nonrenewable resources.
What are fossil fuels? (Uranium is also accepted as nonrenewable)
Doing this to electronic devices when they are not being used saves power, because they use energy even when turned off.
What is unplugging them?
This is the scientific name we use for "heat" energy, which comes from moving particles inside matter.
What is thermal energy?
When you use your muscles to ride a bike, your body is transforming chemical energy from food into this movement energy.
What is kinetic energy?
This type of modern light bulb is highly efficient because 95% of its energy becomes light, and only 5% is wasted as heat.
What is an LED bulb (Light Emitting Diode)?
This renewable resource uses giant turning turbines to capture the movement of air caused by uneven heating from the sun.
What is wind energy
This simple action saves energy at school because manufacturing new materials from scratch requires significantly more power.
What is recycling (paper, plastic, or metal)?
X-rays at the dentist and microwaves heating your food are both everyday examples of this specific form of energy.
What is radiant energy?
When wood burns in a fireplace, chemical energy transforms into these two ending forms of energy.
What are thermal energy and light energy?
This old-fashioned type of bulb wastes 90% of its electrical energy by turning it into heat.
What is an incandescent bulb?
This nonrenewable energy source was formed from ancient sea creatures buried millions of years ago and is used to make gasoline for cars.
What is oil (or petroleum)?
Swapping out light bulbs that use a lot of energy at home for light bulbs that use less energy is an example of this concept.
What is energy conservation?
This happens to the individual particles inside an object as its thermal energy increases.
What is they move faster?
Wind turning a turbine or moving water spinning a wheel to create electricity are examples of mechanical energy transforming into this form of energy.
What is electrical energy?
This is the specific reason a metal spoon gets hot when left inside a warm bowl of soup.
What is heat transfers from the hot soup into the cooler spoon?
This renewable energy source relies on large dams to use the mechanical energy of falling or moving water to spin turbines.
What is hydroelectric energy
Keeping these closed during a hot summer day helps conserve home energy by blocking outdoor thermal energy from entering.
What are doors and windows
