This document outlines objectives and content about energy for a science lesson. It begins with objectives to define energy, discuss energy transfers, examine collisions, and explore moving stationary objects. It then provides an overview of the content to be covered, including re-examining forms of energy and focusing on energy transfer. Various topics within these areas are then explored in more depth, such as defining energy, demonstrating examples of energy transfer including through popcorn making and clothing insulation, examining collisions in videos, and investigating the transfer between potential and kinetic energy in a swinging pendulum.

1 - WHAT IS ENERGY?
Energy is an ability to produce a change and the
capacity to do work. We can’t actually see energy
but we can see evidence that energy exists and
that it is converted or transferred from one form to
another.
We can also observe how energy causes matter to
change in various ways, e.g.:
•a change from one state to another;
•a change in chemical composition, e.g. during combustion or
corrosion which happens during a chemical change;
•a change in temperature;
•a change in motion;
•a change in physical properties e.g. size, shape.

1 - WHAT IS ENERGY?
Energy does not remain in the same form always.
To cause change, energy itself changes from one
form to another.
During changes, energy is always conserved, i.e.,
it is not created anew nor destroyed.
Therefore, the total amount of energy in the
universe remains constant. You learned this Law
of Conservation of Energy in Grade 10.
So… all of the energy has to end up some-where,
either in the original form or in a different form.

Having watched those videos, what do you
understand by the term ‘energy transfer’? Does
energy transfer mean the same thing as ‘energy
transport’? Think about the terms and discuss them
within your group!
• TRANSFER of energy – involves energy conversion from
one form to another or inter-conversion of energy.
• Energy transfers take place all the time from potential to
kinetic energy. For example, potential energy in the
sun, wind, water, fossil fuels, batteries, foods, nuclei and
stationary objects can be changed to electricity, light,
heat, sound, mechanical and muscular energy.
• Energy transfers usually produce more than one form of
output energy. Check the diagram on the next slide.

Energy Transmission And Storage
Transmission is the “bulk transfer” or
transport of electrical energy from
generating power plants via ‘power’ lines
to electrical substations near towns/cities.
Interconnected transmission lines are part
of the power grid.
Stored energy - You learned that chemical
energy is stored in food molecules (when
you did photosynthesis digestion and
respiration).
Stored chemical energy is also in a battery.
Energy can also be stored in many other
ways. Gasoline, natural gas, food, water
towers, a wound up alarm clock, a Thermos
flask with hot water are all stores of energy.
They can be transferred into other kinds of
energy.

Review Activity 2.1 – An Example
Feedback to Question 2.1. - What energy transfers
occurs to make your pop corn?
1.When the pop corn machine is plugged into the
electrical mains and switched on, it changes
electrical energy to thermal/heat energy which
heats the corn.
2.The heat changes the stored chemical energy in
the corn, causing the corn to “pop” or burst open
and it also now has kinetic energy because some
popped corn “jump” as they pop and the popped
corn overflows the bag and forms a pile in the
machine.
3.Change to sound energy also occurs because
some corn make the popping sound you hear.

Question 2.2 How does thick woolen clothing like
this affect heat energy transfer?

Jacket, headwear and neck scarf keeps you warm in cold weather
because the thick woolen materials of the cap and scarf and the
filling between the layers of the jacket holds trapped air that
prevents heat energy transfer from your warm body to the cold air
outside.

ENERGY TRANSPORT
TRANSPORT of energy, unlike energy transfer or inter-
conversion, involves carrying an object that has
energy from one place to another, e.g. a ball
moving through the air or waves moving are forms
of energy transport.
You will consider various methods of energy
transport in the next lesson!

Have you ever played tennis? pool? cricket? football? If so,
you’ve experienced collisions e.g. between a pool stick and
the balls, between ball and bat, between your foot and the
ball.
Collision = The brief, direct contact between two or more
bodies that results in a net impulse on each body.

Feedback to Question: Was there any evidence of energy
transfers from the collisions seen in the videos? What? When?
For anything to happen, energy has to move, change form,
be transferred! Movement involves one form of energy being
transformed into another form (inter-conversion). Energy to
move the ball in these collisions comes from the footballer as
well as the tennis players. For example, the footballer
transfers some of his stored energy at the collision that occurs
when he kicks the ball and starts it moving with kinetic
energy.
Each tennis player transfers some of her energy to the
racquet. At the instant that the racquet hits the ball you
have a very violent collision with very large forces and
energy is transferred to the ball. The moving ball has a lot of
kinetic.
Every time a ball is kicked or hit, the ball actually compresses
and gets deformed from all the force that is applied to it. In
each process a lot of energy is transferred into the form of
heat, friction, sound and vibrations. Then the ball changes
direction and expands back into its original shape.
Do the activity on collisions as indicated in your SIM.

Vehicular Collisions
Feedback to Question 2: What energy transfers do you
think take place from the collision of the vehicles?
In (a) The total kinetic energy before the collision is not
equal to the total kinetic energy after the collision. A
large portion of the kinetic energy must have converted
to other forms of energy.
Did you notice? ….
In the videos the vehicles rebounded from the collision,
continued to move, then came to rest.
There was sound energy and fire (so thermal energy is also
inferred!). So kinetic energy is converted to other forms of
energy.

it typically hangs vertically in its equilibrium or
‘resting’ position, where it has gravitational potential
energy.

Activity 4.1 - A Swinging Sphere
26
Each time the pendulum bob swings,
starting from A, its kinetic energy
increases as the bob acquires velocity
and approaches the equilibrium
position at D.
Then the kinetic energy decreases as
the bob moves further away from the
equilibrium position to G.
At the same time, as the bob moves
towards its equilibrium position D, it
decreases its height and decreases its
potential energy. Then, it begins to
increase potential energy again going
up to G. Cont’d
When the bob is displaced from its equilibrium or resting position, and is
lifted above its resting position A, and released, the conversion or
transfer of gravitational potential energy into kinetic (motion) energy
occurs as it begins its back and forth movement. The movement is
regular and repeating.

A Spring Pendulum
28
The spring pendulum is a mass (brown)
suspended from a spring (blue). It is an
example of an object that undergoes
vibrational motion. The mass hangs at a
resting position. If the mass is pulled
down, the spring is stretched. Once the
mass is released, it begins to vibrate. It
moves back and forth, vibrating about a
fixed position. It has three modes of
oscillation and energy will slowly transfer
back and forth between the modes.
Watch the demonstration your teacher
has set up.

Compressing A Spring
Watch from 1.34 – 2.00 and try it also if you have a

One instance where energy is converted and
transferred would be when you press down a spring.
The energy (which is in the form of stored chemical
energy in your muscles) is converted to elastic
potential energy of the spring! If you let go off the
spring, it will jump back/spring up: the energy it will
use to spring up is actually the chemical energy
that was in your arms but which had now been
transferred to the spring
