Hello Today we did a lab and one of the activities was having a compass underneath a wire while the current was off. The wire was straight so that it was directly aligned to be with the needle of the compass. One the current was flowing, the compass arranged itself in that it was not exactly 90...

From my understand, electric field is the force emitting from a charge. This means that if a charge was placed in the vicinity of the charge that was emitting the field of force, that charge placed would experience a force from it. How does potential energy differ from this? I understand that...

Hello there, I was wondering if anyone wouldn't mind helping clarify what is occurring with a charged capacitor for me. I understand that in a charged capacitor one conducting plate is negatively charged and one is positively charged due to the distribution or rearrangement of electrons. There...

Thanks everybody. One last time for review for what I simply need to know: The electrons on a capacitor are attracted to the positive end to the battery which creates a current, or flow of charge, through the circuit which causes the electrons to migrate from one side capacitor...

In regards to circuits then, should I just for now with current level of physics I'm at, know that a battery simply is what drives the current? And that's it? I'm in physics 2 electricity and magnetism, from what I can recall is that the battery has a potential difference inside and it drives...

I understand that the current is charge migrating per time, usually in seconds, and that charges will continue to flow to the capacitor to store energy so to speak until the potential difference between the capacitor is equal to the battery due to the fact that once it is equal the battery can...

Hello, Reviewing for the test and there are still some things I'm not sure about so I thought I'd ask here and hopefully come across someone that can help. I swear I knew this, but I have not been diligently reviewing as much as I should so I think I forgot and became confused. When a...

Hi Scottdave I'm sorry I forgot to imply that it is actually that the negative charges that are moving, although use positive charges for easier demonstration. Based on what you said, what exactly is inside the battery then? An imbalance of charges on both ends? Similar to a charge capacitor...

Hello there, I'm confused on several things such as the potential difference it provides and how it pushes the charges through the wire or conductor or circuit. So when a battery comes into contact with a wire, the positive charges flows from high potential through the circuit to the low...

Homework Statement A 10kg block moving at 1 m/s hits another 10kg stationary block. Those two blocks (now stuck together) collide with another 10kg stationary block. What percent of the original energy is lost after the two collisions? Homework Equations m1v1 + m2v2 = (m1+m2)v3 Kinetic energy...

Excellent observation my dear Watson! Thank you for catching that, yes you are correct. The equation is (Final velocity)^2 = (Initial velocity)^2 + 2(acceleration)(distance), and I had input time in the value for acceleration. Correct me if I'm wrong, I should have used the formula (change of...

Homework Statement Hello there physicsforums, I have a problem that I'd like feedback on as I'm not sure if I had solved it or approached it correctly. A ball that is traveling 5m/s is 30 meters above a person who is standing still. How fast must the person travel in order to catch the ball...
