What does the word ‘energy’ mean?

Energy is the ability to do work.

We need energy to do everything.

Without energy, nothing can move or change.

Energy is everywhere and takes all sorts of forms.Slide10

Types of Energy

For each type of energy, use the pictures to help you write your own definition for the energy type.

Your definition should be in a full sentence and use at least one example from the pictures.Slide11

Peer Mark

Can you help your partner improve their definitions?

Tick any scientific keywords they have used.

Add any useful additions in purple pen.

This is BEST work because…

You can transform your work by…Slide17

Check your group!

ou may wish to STOP AND USE the alternative ‘Energy types, examples and transfer’

Power point

USE from SLIDE 25 onwards from current Power point WITH LESSON 5Slide18

Energy storage

Energy can be stored in 3 main ways

:

Chemical potential

Gravitational potential

Elastic potentialSlide19

10.4 Potential energy

What does ‘potential’ mean?

Any form of stored energy is called

potential energy

Potential means

the ability

to do something that hasn’t been

done

yet.Slide20

10.4 Potential energy

Elastic potential energy (EPE)

This is stored in elastic materials such as rubber, metal springs and elastic.Slide21

Chemical Energy

Chemical

potential

energy (CPE)

Energy

is stored

in the bonds between

atoms.

W

hen

the bonds are broken, often by burning (oil, gas, wood) or by a chemical reaction (digesting food, battery) the energy is released

.Slide22
Slide23

10.4 Potential energy

Gravitational potential energy (GPE)

Gravitational potential energy is energy an object has because it is high up

.

This is due

to gravity pulling it down

It only releases this energy when it falls down.Slide24

10.4 Potential energy

.

So what happens to the energy in the rock when it falls?

GPE is transferred as kinetic energy (KE) in the movement of the falling rock.

The energy is then transferred to

the

ground when the rock hits the floorSlide26
Slide27

Label your diagram - where is gravitational

potential energy and where is kinetic

energy?

Gravitational potential energy (GPE)Slide28

Materials and equipment

Step by step

method

Fair testing, what you will measure and record

How could you test this question?

Aim: How does height affect the amount of gravitational potential energy in a ball?Slide29

How does height affect the amount of gravitational potential energy in a ball?

Method

Hold

the ball 10 cm above the ground

. Use a meter stick to measure this.

Drop the ball in a straight

line.

Measure how high the ball bounces back up.

Record your results

.

Repeat two more times at 10 cmRepeat for 20 cm, 30 cm, 40 cm, 50 cm, 60 cm etc.Slide30

Calculate averagesDraw a graph of your results – use your averages column. Put the height dropped along the x axis and the averages height bounced along the y axis How does height affect the amount of gravitational potential energy in a ball?Slide32

How does height affect the amount of gravitational potential energy in a ball?

Quick check

What is gravitational potential energy?

How

did we investigate this?

What

did we find out? Slide33

How does height affect the amount of gravitational potential energy in a ball?

Write a conclusion to explain what you have found out. – what do you results show and why is this?

Use the sentence starters to help structure your

conclusionSlide34

Plenary

Write one question in your book to answer before this box disappears!

What energy types can you see in use in this picture?

What energy transfers are happening?

What energy stores are present?Slide35
