What is the difference between gravity and the electric force? answer: Gravity is always an attractive force whereas the electric force can be repulsion or attractive. 
 How would the field force change is a previously neutral dot in the center of a row of negative charges was changed to positive?
(- - + - -)
Answer: The negative charges would been have repelled away from the neutral center because they would have been repelled the negative charges on the opposite side of the neutral center. If the center is positive the negative charges will move in slightly because they will be attracted to the positive center, but still repelled by the negative charges opposition the positive center. 

Level 3 Question:
What would happen is the distance between two charges was doubled?
Answer: the force between the charges would be x4 weaker. 
How would you use the mass of a proton or electron to determine the charge?
Answer: You don't; charge is a constant, not determined by mass. 
What would happen if, in the equation E=F/q, q was doubled?
Answer: E would decrease by half. 
Level 4 Question: 
What is the relationship between Coulomb's Law and Law of Universal Gravitational? 
Answer: Both Coulomb's law and Law of Gravitation involves central forces and are inverse square laws. They are also both concern the proportionality. However, Coulomb's law involves electrical forces and has both attractive and repulsive forces. Gravitation only involves attractive forces. 
What examples of Coulomb's Law are found in nature?
Answers Included, but not Limited to: Balloon that sticks to the wall (distance is inversely proportional to force so since the opposite charges are closer together, the force of attraction is stronger than the force of repulsion), plastic wrap sticking to your hand or any other object (the static charge caused by the imbalance between the positive and negative charges in the plastic wrap), magnets repelling/attracting (Coulomb's law exhibited through its charge, magnitude and distance)]]> 2017-04-26 21:43:40 UTC https://padlet.com/tec430/qsp7zcuas4k7/wish/168507236 https://padlet.com/tec430/qsp7zcuas4k7/wish/168507327 Level 2: What are the units for coulumbl's law?
A: N
Level 3: How does the change in the r value affect the electrical force?
A: If the r is bigger the net force is small and if the r is small the net force is bigger. 
Level 4: In a situation involving 3 or more charges how do you calculate the Net force?
A: The net force would be the vectors sum of all the individual forces acting upon it. 
Level 5: What is the charge on an object that has 1.25x10^17 electrons in excess on its surface? 

1.25x10^17 e(1C/6.25 x 10^18 e)= .200x10^-1c= .0200C

How would you compare electrical force versus gravitational force?
A: A major difference is that gravity is always an attractive force whereas the electric force can be either attractive or repulsive. In terms of the formula, electrical force has Coulomb's constant (8.998x10^9) and uses the objects' charges as opposed to gravitational force which has the gravitational constant (6.674x10^-11) and uses the objects' masses. Both forces are affected by the distance between the objects. There is a direct relationship between charges and the electrical force, and a direct relationship between masses and the gravitational force. There is an inverse relationship between both forces and the distance between the objects. 
Level 3:
How would you use Coulomb's law in order to understand what would happen to the force if you double one of the charges?
Since the charge and electrical force have a direct relationship, increasing one would increase the other. Thus, if we double one of the charges, the force also doubles. 
Level 4:
How would you test to see which object out of two options has more electrical force placed on it?
Conduct an electrical field test which tells us which direction a positively charged particle will move using the equation E=F/q in which F is the magnitude of the force and q is the magnitude of the test charge. If the positive charge has field lines pointing away from it, that means there's repulsion and so the test charge is also positively charged.
Level 5:
Based on what you know, about electrical charge, how would you solve for electrical field strength?
Because electrical field is dependent on force and test charge, electrical field= Force/test charge.]]> 2017-04-26 21:50:09 UTC https://padlet.com/tec430/qsp7zcuas4k7/wish/168507810 https://padlet.com/tec430/qsp7zcuas4k7/wish/168507851 Level 2:
