Matter
Define matter.
Matter is anything that takes up space.
Define energy.
Define the word "transfer."
To pass on. To give over.
What is a magnet?
A magnet is an object that attracts certain materials, such as iron (+steel, nickel, and cobalt).
What is the world's smallest magnet?
Electrons!
What is matter made of?
Atoms!
Define the difference between potential and kinetic energy.
Potential energy: stored energy
Kinetic energy: energy in motion
What are the three types of thermal energy transfer?
Conduction, convection, and radiation
Describe a magnet's poles and their properties.
Should include: 1) North and South 2) Properties of repulsion and attraction
south
What are the three states of matter?
Solids, liquids, gases
Give an example of kinetic energy.
What types of energy transformation occur when one plugs in a fan?
Electrical > mechanical > sound
How are electricity and magnetism related?
Magnetism creates electrical currents, and electrical currents create magnetic fields.
Who expanded our knowledge of the universe's invisible forces (specifically that invisible, magnetic fields exist and that magnetism and electricity are related)?
Michael Faraday
True or False: Matter cannot be created nor destroyed, only rearranged.
True
Give an example of potential energy.
Chemical energy, nuclear energy, gravitational energy
Describe a situation in which three stages of energy transformation occurs.
Answers will vary.
Where, supposedly, was magnetism first "discovered"?
Greece!
What was James Clerk Maxwell's contribution to Faraday's findings?
James Clerk Maxwell created mathematical equations that backed up his theories about fields of force.
Give an example of chemical energy found in the world.
Food. End of a match. Gunpowder.
Describe, in steps, how a thermal updraft tower functions.
When the sun shines on a thermal updraft tower, the heat gets trapped at its base. Because hot air is more dense than cold air, it rises inside the tower. The colder air is less dense and sinks. This creates constant circulation (also known as convection or an updraft). The wind turbine (or propeller in our experiment) moves from the constant air being sucked in, heating, and rising. This propeller’s mechanical energy is converted into electrical energy by generators.
Can objects interact with each other from a distance? If so, explain how such a thing is possible.
Objects can influence one another or interact with one another from a distance. Gravity is constantly exerting force on other objects without “touching” them. You’re not floating away, are you?! Magnets can force other magnets to move without touching them (if same domain poles get closer to one another).
True or false: Energy is stored in the electric fields between charged particles and magnetic fields between magnets.
TRUE!
