Here are the correct words to fill in the blanks on your worksheet, organized by section.
Law of Conservation of Energy
* Energy can be neither
created nor destroyed by ordinary means.
* Energy can be
transformed (or converted) from one form to another.
* The total amount of
energy is the
same before and after any energy transformation.
Energy Transfer
* Energy
TRANSFER is the
movement of energy from one object to another object.
*
Example: A cup of hot tea has
thermal energy. Some of this thermal energy is
transferred to the particles in cold milk, in which you put to make the coffee cooler.
Energy Transformation
*
Single Transformations
* Occur when
one form of
energy needs to be
changed into another to get work done.
*
Multiple Transformations
* Occur when a
series (or chain) of energy transformations are needed to do work.
* An objects energy can be:
* As velocity
increases, kinetic energy
increases and potential energy
decreases.
* As velocity
decreases, kinetic energy
decreases and potential energy
increases.
*
WHAT IS THE TYPE OF RELATIONSHIP KE AND PE HAVE?
*
Inverse relationship (As one goes up, the other goes down).
Roller Coasters
* Does energy get transferred or transformed?
Transformed
* As you move up to the first hill on a roller coaster the distance between the coaster and the Earth
increases, resulting in an increase of
Gravitational Potential Energy.
* At the top of the first hill you have the
maximum (or most) Gravitational Potential Energy.
* As you begin your trip down the hill you
increase your speed resulting in a transformation from
Potential Energy to Kinetic Energy.
* At the bottom of the hill right before it goes back upward the
Kinetic Energy is at its maximum, but the
Potential Energy is at its minimum.
* As it starts to move up the next hill or loop KE is
transformed back into GPE.
Parent Tip: Review the logic above to help your child master the concept of kinetic and potential energy worksheet answers.
