Hello,
Please work on the following assignment phet simulation
Coulomb’s Law Lab
We will use an online simulator for this lab. Please Google “ Phet Coulomb’s Law Interactive” or use the following link:
For an introductory video about the lab, click here: Intro Video or in YouTube, the same video. You can ignore the part about the calculator, as you are not doing that part.
Move the charges around and change the size of the charge using the sliders at the bottom.
- What happens to the force as you increase the charge? (Does the force go up? Down?)
- What happens to the force when you decrease the charge?
- Are Charge and Force DIRECTLY related (if one goes up so does the other) or INVERSELY related (if one goes up the other goes down)? Explain.
- Now, pull the charges farther apart (leaving the charge the same). What happens to the force?
- Now, put the charges closer together (leaving the charge the same). What happens to the force?
- Are Distance and Force DIRECTLY related (if one goes up so does the other) or INVERSELY related (if one goes up the other goes down)? Explain.
- Set both charges to a positive charge. Which direction does the force go?
- Set both charges to a negative charge. Which direction does the force go?
- Set one charge to a negative charge and one to a positive charge. Which direction does the force go?
- Look at questions 7 through 9. Objects ATTRACT if the force goes towards the other object. When do the charges attract
- Look at questions 7 through 9. Objects REPEL if the force goes away from the other object. When do the charges repel?
