ENERGY TYPES
Where does all energy find its source?
THE SUN
Is a pencil on a table potential.
TRUE
If a ball is thrown in the air, where does it have the most kinetic energy and why?
The ball has the most kinetic energy as it reaches the ground because this is where it has the highest velocity.
All of the following are nonrenewable resources, EXCEPT A. Water B. Coal C. Natural Gas
WATER
As kinetic energy increases what happens to potential energy?
DECREASES
Define potential energy
Potential energy is energy that is stored.
Is a rolling ball potential?
NO
If a ball is thrown in the air, where does it have the most potential energy and why?
The ball will have the most potential energy when it reaches its maximum height, as height increases so does PE
What is energy transfer?
Energy moving from one thing to another and staying in the same form.
As potential energy increases what happens to kinetic energy?
DECREASES
Define kintetic energy
Kinetic energy is the energy of motion.
Does a rollercoaster[going down] have kinetic energy?
YES
What is the law of conservation of energy?
Energy is neither created nor destroyed; it is only transferred or transformed
What is energy transformation?
Energy changing form.
When we drive our cars we are increasing our _____ footprint.
CARBON
A ball sitting on a shelf 5m high has what kind of energy?
POTENTIAL ENERGY
Give an example of potential energy?
YOUR PICK KID
Give an example of the law of conservation of energy.
Gas is put into the car as chemical potential energy; the engine transfers the PE to KE as the car moves.
What is the energy transformation for a toaster?
ELECTRICAL TO THERMAL

A horse running across a field has what kind of energy?
KINETIC ENERGY
GIVE AN EXAMPLE OF KINETIC ENERGY
YOUR PICK KID
Explain how the energy you use throughout the day is really solar energy.
Energy from the sun causes plants to grow, animals and people eat plants, people eat animals thus our energy comes from the sun. Energy from the sun causes plants to grow, plants become fossil fuels, people use fossil fuels for power, gas, etc. Thus our energy comes from the sun.
What is the energy transformation for a television?
Electrical to sound to light. Wasted thermal energy.
In what ways are PE and KE different?
KE depends on Velocity. PE depends on gravity and height
