DESCRIPTION
3.11 PART A | POWER POINT
Citation preview
Mr. Smet’s Scientific Studies
STUDENT POWER POINT
3.11-3.22
This Power Point presentation has been made to walk you through the worksheet. It will answer a short number of the questions from your packet but also go through the key points of answering the other questions with examples.
The questions in this packet will be helpful for understanding the question on Thursday. This means that, by Thursday, you should be able to answer the questions on your own without the help of this PowerPoint.
Work with urgency!
HOW THIS WORKS
3.11PART A | POWER POINT
Kinetic EnergyKinetic energy is the
energy of motion.Anything that is moving
has kinetic energy.Kinetic Energy usually
has both: Mass Speed
Potential EnergyPotential energy is
stored energy.Anything that can become
lower has potential energy.
Potential Energy usually has both:
MassHeight
POTENTIAL AND KINETIC ENERGY
Fill in the definition part of your chart.
Potential EnergyAn airplane is flying
through the air. This has potential energy The airplane is above the
ground.
A skateboard is rolling on the ground. This does not have
potential energy. The skateboard is on the
ground and cannot go any lower.
PE AND KE EXAMPLES
Kinetic Energy• An airplane is flying in
through the air.• This has kinetic
energy.• The airplane is
moving.
• A skateboard is rolling on the ground.• This has kinetic
energy.• The skateboard is
moving.
KINETIC ENERGY EXAMPLES
Get ideas for what to draw.
POTENTIAL ENERGY EXAMPLES
Get ideas for what to draw.
Go ahead and draw your examples of kinetic energy
and potential energy.
Altogether, this should take 2-4 minutes to finish.
DIRECTIONS
Draw your examples for PE and KE.

PART D | POWER POINT AND PHET
Energy TransformationAn energy
transformation is when energy changes from one type into another.
Potential energy transforms into kinetic energy when moving down.
Kinetic energy transforms into thermal energy when something hits the floor and during friction.
Energy TransferAn energy transfer is
when energy moves from one place to another.
Thermal energy transfers to another object when two things touch (conduction).
Thermal energy transfers to objects far away through waves (radiation).
Thermal energy rises in liquids and gases when hot molecules rise (convection)
ENERGY TRANSFORMATION VS.ENERGY TRANSFER
Fill in the definition part of your chart.
Energy cannot be created or destroyed—which means that when we
“lose” one type of energy, it either changes into a different type (energy
transformation) or moves somewhere else
(energy transfer).
LAW OF CONSERVATION OF ENERGY
Read this slide
As the child moves down the hill, her potential energy transforms into kinetic energy. As friction slows her down, her kinetic energy transforms into thermal energy (and even sound energy). Energy is never destroyed.
