Electric force is created by the attraction between __________ and__________ charges.
What is positive and negative?
What kind of force gravity is (contact or non contact)
What is non contact?
What north and south poles do (pull together or push apart)
What is pull together?
As you move closer to an electron/proton, the electric force becomes ______________
What is stronger?
If you release a tennis ball from 5 feet above the ground, it will bounce a _________________distance than if you release the tennis ball from 5 inches above the ground.
What is farther?
As you move away from a magnet, the magnetic force becomes _________________
What is weaker?
More electrons/protons (a greater magnitude, or bigger size) of charge makes electric force _______________
What is stronger?
The speed/velocity of a sky diver _______________the longer they are falling for.
What is increases?
What is magnetic?
Lightning happens because the ground and the clouds have ________________charges.
What is opposite?
Something with more mass has __________________ kinetic energy.
What is more?
Maglev trains have less friction than regular trains because_________________
What is the repulsion between like poles makes the Maglev train levitate?
Why the balloon can move the soda can after you rub the balloon against your hair
What is (rubbing the balloon against your hair causes the balloon to gain electrons and a negative charge. The soda can is pulled towards that negative charge if the can has a positive charge, or pushed away if the can has a negative charge?
As speed/velocity increases, kinetic energy _______________. Support using evidence (from our experiments, mathematical equations, etc.)
What is increases and (the faster moving tennis ball moved the foam peanuts more, if you drop a tennis ball from higher up it moves faster, KE=0.5*m*v2, so as mass increases, so will kinetic energy)
The reason why materials like wood and plastic cannot become magnets
What is their electrons' tiny magnetic fields are not organized into domains (areas where all the magnetic fields are facing the same direction)?
