Worksheet time: 35mins
movement of energy from one object to another or one place to another
when energy changes from one form to another
What is the difference between energy transfer and energy transformation?
Energy transformation involves no movement of energy.
Energy transfer is energy moving from place to place or object to object, and Energy transformation is when energy changes from one form to another.

energy transformation
gravitational energy
kinetic energy
What evidence shows that energy has transferred?
ball moves from a kick
light comes on from a flashlight
a sound is heard from an explosion
a cup gets hot when soup is poured into it
What changes when energy transfers?
Hint: ( you kick a soccer ball in the grass)
nothing changes, no energy is transferred
the object that is touched moves or changes position
the object that is touched will stay in the same spot
all the above
What different forms of energy are used in hydroelectric power plants?
(Put this in order, carefully think about it)
hydro means water
a flow of water down hill
flowing water pushes on the turbine blades turning them
turning turbine blades transfer energy to the generator
generator transforms energy into electrical energy for power plant
The person in the picture is listening to sound made by someone talking. This is evidence that energy can be
Transferred from place to place
Transferred through contact between objects
Transformed from sound to work
First created and then destroyed.
Explain how energy transfers and changes to matter related?
Beam of light from a flashlight providing evidence of light transferring from a source:
Chemical energy in the batteries in the flashlight is changed into electricity.
Explain how energy transfers and changes to matter related?
Melted ice cubes in the sun
Heat energy from the sun transfers to the ice cubes causing it to change from a solid to a liquid.
Explain how energy transfers and changes to matter related?
Connect and disconnect a charger to turn on and off an electronic device?
Energy transfers from the outlet is transferred to the charger through the charging cord and into the electronic device
What happens to energy during a collision?
Energy moves from one object to another.
Energy of motion of one object may be transferred to another during the collision.
Some energy of motion is transformed into other forms of energy.
Speed always means the same thing as how fast?
How does the weight (mass) of an object affect its energy of motion?
Hint: A baseball pitched at 100 mph and a street bike racing at 100 mph.
Which object will have more energy?
The weight(mass) of an object affects its energy of motion. Greater the weight, greater the energy of motion.
What is going on in a Newton's Cradle?
It shows transfer of energy through collisions in a predictable pattern.
Most of the energy of motion is transferred back and forth between the balls.
Some of the energy of motion in these collisions is converted (transformed) to sound.
all the above
Changing the conditions in a collision changes the outcome of the collision?
example: If the speed of a car increases, it will have a more forceful impact with more energy transfer.
A kid holding a basketball. What kind of energy is this?
Kinetic energy
(also known as energy of motion)
Thermal energy
(also known as heat energy)
Potential energy
(also known as stored energy)
A kid dribbling two basketballs? What kind of energy is this?
Kinetic energy
(also know as energy of motion)
Thermal energy
(also known as heat energy)
Potential energy
(also known as stored energy)
When you add hot soup to a cold bowl, _______ energy transfers from the soup to the bowl.
kinetic/motion
potential/stored
thermal/heat
If a book is falling off a shelf, the book has _______ because it changing its _______?
energy of motion; position
Playing a drum produces _______, which is a form of energy that you can hear.
When a bowling ball hits the bowling pins, a sound rings through the bowling alley. The change from motion of energy to sound energy is an example of __________?
Energy is the ability to cause _______?
Heat, light, and sound are examples of ________?
forms of energy
forms of mass
forms of force
forms of matter
A marble at the top of a ramp has _________, because at any moment it can move down the ramp.
energy of motion
stored energy
Computers are powered by _______?
________ is a measure of how fast an object is moving, and ______ is a measure of how far apart objects are.
When light energy is converted to heat energy, this is known as ________.
energy transformation
Maria has been studying sound energy at school. She has written an explanation of sound using an example from her experience. Maria says, "Sound energy only travels over long distances. When I am on the playground, I can hear the bell that rings across the field that lets me know recess is over." Do you agree with Maria? Use you own evidence to support your answer.
No, I do not agree with Maria, because sound can travel over long or short distances.
Yes, sound energy only travels long distances.
What is the relationship between the speed of an object and its energy of motion?
Energy of motion decreases as speed increases.
As speed increase, the amount of energy of motion increase.
You roll a toy car down a ramp into a stack of four blocks. the top block falls off the stack.
You add some weight to the toy car and repeat the test, changing ONLY the weight of the car. This time, the top two blocks fall off the stack.
Based on this pattern, explain the result in terms of energy change?
The increase in weight of the toy car leads to greater energy of motion, resulting in more blocks falling off.
The weight of the car decreases the energy of motion, causing fewer blocks to fall.
The school cafeteria keeps cooked food under lamps until students pick it up to eat. The top of each portion of food stays warmest.
What two kinds of energy are the lamps transferring to the food?
chemical energy, food energy
mechanical energy, electrical energy
nuclear energy, light energy
A student named Maria made a sketch of her solution to a problem. Maria's solution includes plugging a lamp into a timer that works in a wall socket. At the same times each day, the timer switches the lamp on an off. Her solution also includes a container of water that allows water to drip slowly through a hose down into the planter. The container of water sits on a stack of books so it is positioned higher than the planter.
Complete the labels on Maria's diagram to identify the types of energy that are converted in her design. (select two answers)
stored energy to energy of motion
(plant)
electrical energy to light energy
(lamp)
chemical energy to light energy
(lamp)
energy of motion to stored energy
(plant)
