Day 84

WARM-UP

Draw the positively charged puck, and the goal. Then draw in one positive or negative charge in the correct location so the puck would go in the goal

HOMEWORK

Still struggling with Coulomb's Law? Here's some help: Video LINK

1. If you didn't finish them in class, complete 084B and 084C

2. Electric Field Video: LINK

Video Questions

1. Are electric field lines visible? Which other force(s) are invisible?
2. If you put a negatively charged particle inside an electric field, and it accelerates away, is it experiencing a force? What kind of force?
3. What kind of charge would be present to cause the negative charge to accelerate away?
4. Draw a positive particle. Which way will the field lines point? Draw them
5. Use our new equation for force (F=qE) to solve the proton problem with Mr. Andersen
6. In a similar fashion, solve the electron problem presented at 4:45
