Answer the question below. For help, see pages 513-517 text.
Name 3 ways in which the capacitance (ability to store charge) of a capacitor can be increased.
State clearly the difference between
a) Electric Potential and Electric Field
b) Electric Potential and Electric Potential Energy
Answer in the space below.
Recall the demonstration in class today with the metal ball hanging from the string. There were 4 parts:
1: PVC pipe was rubbed with fur
2: Pipe was brought up to ball and attracted it.
3. Ball touched pipe and immediately repelled
4. I touched ball and it started attracting again.
Explain how charge was transferred in each stage of this demonstration. Use the correct terms of conduction, induction, and friction when doing your explanation.

Please answer the questions below. Additionally, if you want to use this space to discuss the demo, please feel free.
1. If you charge a pocket comb by rubbing it with a silk scarf, how can you determine if the comb is positively or negatively charged?
2. Why does a shirt or blouse taken from a clothes dryer sometimes stick to your body?

Hi all,
This blog is meant for both honors and general classes tonight. On page 3A of your packet, you will see question #3, which deals with a broom. Answer the question in the space below, and then reply to at least 1 other student's answer. You can comment on someone from your own class, or someone from the other class.
Please answer the following question.
1) Will the acceleration of a car be the same when it travels around a sharp curve at 60 km/hr as when it travels around a gentle curve at the same speed? Explain.
Please answer the following question below:
If you were in a car that was out of control and had to choose between hitting a concrete wall or a haystack, common sense tells you to choose the haystack. Explain using terms discussed in today's class why hitting the haystack is the smarter idea.
Please answer the following questions on a separate sheet of paper to hand in on Monday. Answers are posted in bold so you can check your work. Your homework must show ALL WORK.
1. Batman is chasing after some unlucky villains on a rooftop 40 m above the ground. If the villains jump to the next rooftop which stands 44 m above the ground, what jumping velocity will Batman need to inflict some justice? (vi = 8.85 m/s)
2. As a prank, you decide to stand on the roof of Springfield High School (20m) and wait for Mr. Bonnette to walk by below you. You heave a large water balloon at an angle of 10° with a velocity of 10m/s (bad idea). Since Mr. B is 1.8m tall, what would be the velocity of the balloon if he were to be hit in the head? (vf = 21.37 m/s)
3. You are playing leap-frog. What minimum velocity would you need to leave the ground with if you had to jump over your friend 0.5 m high and pass with a speed of 0.2 m/s? (vi = 3.14 m/s)
Please respond to all questions below:
1) If the kinetic energy of an arrow is quadrupled, by what factor has its speed increased?
2) If the velocity of an arrow is quadrupled, by what factor does its kinetic energy increase?
3) If you do 100 J of work to elevate a bucket of water, what is its gravitational potential energy relative to its starting position?
4) What would the gravitational potential energy be if the same bucket was raised twice as high?
Hi all,
Once you have chosen your group topic for the research report, you may post your choice here. You only need 1 response for the group. However, please indicate whether you are in the 1st block regular physics class or the 4th block honors class.

Answer the following question and respond to another student's post.
You are driving down the highway and a bug splatters on your windshield. Which is greater: the force of the bug on the windshield, or the force of the windshield on the bug? Which effect of the force (acceleration) is greater: the deceleration of the bug or the deceleration of the car? Why?
Please answer the question below by responding to the blog, and then comment on at least 1 other student's answer.
1) When a cannon is fired, how does the size of the force of the cannon on the cannonball compare with the force of the cannonball on the cannon? How does the acceleration of the cannon compare with that of the cannonball? Defend your answer.
Please answer the question below by responding to the blog, and then comment on at least 1 other student's answer.
1) A passenger sitting in the rear of a bus claims that she was injured as the driver slammed on the brakes, causing a suitcase to come flying toward her from the front of the bus. If you were the judge in this case, what disposition would you make? Why?
