Flocabulary – Energy Study Jam – Energy and Matter

3. Energy Energy can be described as potential and kinetic energy.
Energy is a property of all matter.
A change is involved in energy transfer.

4. Energy
The total amount of energy remains constant in all transformations.
Change in the state of matter  motion and arrangement of atoms.
Change of statemass is conserved.

5. Energy Energy is involved in all changes of matter.
Energy is transferred constantly

7. Potential energy
Potential energy is energy that is stored and used later
The object has the ability to do work/ make things happen
Ex: A stretched rubber band has the ability to do work.

8. Potential energy Types of Potential Energy:
Gravitational, elastic, and chemical
Do Brain Pop on Potential Energy.

9. Force
A force is a push or pull on something it is needed to change the motion of something.
(From resting to moving.)
Weight -force of gravity acting on an object.
Newton- is a metric unit that measures force.

10. Mass has an effect!
Mass- Is the measure of the amount of matter in an object.
The mass of an object remains the same no matter what the gravitational pull.
Ex: Astronauts on the moon have the same mass on the moon, even though they are floating!

11. Motion Motion is a changing of position.
It can be described as changes of distance, time and/or direction.

12. Variable
Variables- are the properties of things that can be changed or vary in an investigation.
Examples are: changing of the time, distance or temperature.
Think about an experiment with the ramps. The variable was the height of the ramp.

13. Energy transfer
When energy is transferred from one system to another, the energy input equals energy output Conservation of Energy -Energy is neither created nor destroyed

14. Kinetic energy -energy that is involved in something that is moving
converting potential energy to another form.
Anything that is moving has kinetic energy.

15. examples OF KINETIC ENERGY
Wind
Rolling objects
Falling objects
Flying objects
Anything that is moving

16. Kinetic Energy
Do Brain Pop on Kinetic Energy.

17. Energy transfer
Different forms of energy can be transferred from place to place by…
Radiation
Conduction
Convection

18. Radiation
Radiation -a form of energy transfer that involves light and heat, such as the radiant energy of the sun.

19. conduction
Conduction - a form of energy transfer that involves the passing of heat energy directly between two objects that are touching.

20. convection
Convection - a form of energy transfer that involves the transfer of heat energy through a gas or liquid.

21. Heat transfer
The transfer of heat from warmer objects to colder due to the motion of molecules.
Heat energy- energy associated in the difference in temperature between objects. (Heat can change things!)

22. Study Jam - Heat

23. matter
Matter changes from state to state through the motion and arrangement of molecules.
Matter is composed of tiny particles in motion.
Matter is neither created nor destroyed.

24. States of matter Solid – close particles Liquid – some space Gas
Add energy to become liquid
Liquid – some space
Add energy to become a gas
Subtract Energy to become a solid
Gas
Far apart, fast moving particles
Subtract energy to become a liquid

26. mass
The mass remains the same as matter changes from state to state.
