Vocabulary
Energy that is in motion.
The crest
Potential energy is at its highest at what point?
At the highest point
Opposite poles
attract
What is the purpose of the coil in an electromagnet?
The more coil wrappings the stronger the magnetism.
What is Potential Energy
Energy that is stored up.
What is the bottom of the wave called?
The trough
Kinetic energy is at its highest at what point?
At the lowest point before hitting the ground
Like poles
repel
What are the parts of an electromagnet?
Battery, nail, coil wire, paper clips
What is amplitude?
The height of the wave, that is also responsible for the energy of the wave.
If students are creating a wave with their jump rope and they move the jump rope faster and faster what will happen to the jump rope?
An increase in energy and amplitude
At what point does potential energy turn to kinetic energy
When it no longer goes against the gravitational pull and goes with it
Two like poles being pushed together create what type of energy?
Potential because it is going against the force
What determines the amount of paper clips that can be picked up by an electromagnet?
The number of coils wrapped around.
What is wavelength?
The distance of the wave from Peak to Peak.
If there is low energy which part of the wave is also low?
The amplitude
If you have a ball and you hold it even higher in the air than usual what three things will happen once you drop the ball?
1. kinetic energy will increase
2. bounce of the ball will increase
3. potential energy increase
What is the only thing that matters when determining the electric strength of an electromagnet.
The number of wire wraps around the coil
What is absorbed?
When the material takes in energy from the wave.
A material can only be changed if the light waves are
absorbed by the material
I am running down a hill and skipping over hurdles and rocks. Do I have potential or kinetic energy and explain how?
You have both you are going with the gravitational force which creates kinetic energy and as you are skipping over the rocks you have potential energy.
If I have three opposite facing magnets on a pencil and I place one like facing magnet at the top what will happen to the top magnet?
It will float.
If I used two batteries instead of one what would happen?
The electricity would increase.
