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.
