Energy Sources
What is a fossil fuel?
Fossil fuels are formed from the remains of ancient plants and animals, buried deep inside the Earth for millions of year. They are a nonrenewable energy source.
What is the difference between kinetic and potential energy?
Potential energy is energy STORED in an object as a result of its position or state. Kinetic energy is the energy an object has because it is MOTION.
What is energy transfer?
When energy passes on from one thing to another.
What is the power or ability to make something work or be active
Energy
18 x 5 = ?
90
Name the 3 types of fossil fuels.
Coal, natural gas, and oil.
What is mechanical energy?
Mechanical energy is the energy which is possessed by an object due to its motion or its stored energy or position. Example: any machine.
What is energy transformation?
When energy changes from one form into another form.
Describe collision.
An act or instance of coming together with force or a crash.
What are the steps to long division?
Divide, multiple, subtract, bring down, and repeat.
What percent of the world's energy is supplied by fossil fuels?
80%
An archer's stretched bow
Elastic energy
Name an example of energy transfer
When a bat hits a baseball
How is a catapult energy? What type of energy is a catapult?
Elastic potential energy.
Name 1 way you can save energy.
Turning off the lights when leaving a room
Name the 5 types of renewable energy.
Wind power, solar power, geothermal, hydroelectric, and biomass.
Describe the difference between kinetic and potential energy.
Kinetic is the energy an object has because it is in motion. Potential is energy stored in a object as a result of its position.
Give a specific example of energy transformation.
Flipping a light switch (electrical) to lights turning on (light)
What is the Law of Conservation of Energy?
Energy can neither be created or destroyed.
What does SCPA stand for?
Show respect, Contribute positively, Perform honorably, and Act safety and responsibly.
Describe the difference between renewable and nonrenewable sources.
Nonrenewable means we can't make more, so eventually they will run out! Renewable is any form of energy that come from natural sources and will never run out.
Name ALL the forms of energy (10 forms)
Chemical, nuclear, gravitational, radiant/light, electrical, mechanical, elastic, thermal/heat, magnetic, and sound
Describe how a firework is energy transformation.
When fireworks are ignited, the chemical energy stored in the substances inside transforms into movement (kinetic), light, sound, and thermal energy.
Energy is the ability to....
do work!
