Great news. I am on my last on-line physics module before the Holiday season comes along. I have posted and answered my self-assessment questions (answers appear with *asterisk). Again, please let me know the ones I answered correctly on and the ones I missed (I think there are many because...

Thanks AM. No hints but I will try again. I re-read the module and then looked at the questions again. (2) I am totally confused and not even sure exactly what they are looking for. (3) Boy am I calorically as well as mathematically challenged. At a rate of 40 kJ per minute then 1,700...

Hello again Everyone. I am on to conduction, convection, radiation and the stoppage of all molecular motion. Very complicated information for me. I have completed my next on-line module and about to take my self-assessment quiz. Please review my answers (marked with an asterisk) and let me...

Thanks again for all of your assistance. I think that I understand most of these concepts. I will continue to review before proceeding further. Also, there is no text with this on-line course. However, there is a workbook to write notes and solve some problems. My statement to you was that...

Doc Al. One more comment. I read a little bit about bouyancy and fluid displacement. Does this tie into question #9?

Hey Doc Al. Nylex gave me the ideal gas equation and I completely see that by doubling the pressure you half the volume. What do the variables P,V R and T as well as the constant n represent in the ideal gas equation? As for question #9. The tutorial did not give any equations for a bouyancy...

Hello Everyone. Happy Turkey Day! Even though its a holiday the studies continue. I have moved on to my next on-line module that discusses the physics behind some chemistry concepts. I have posted and answered my self-assessment questions (answer marked with astericks). Please review and...

Got it. Enjoy the weekend and talk to you soon. signed: Inertially "not-as-much" challenged.

Hey DocAl. I think I need to read these questions very slowly and several times before I attack. Question 3 - I change my answer to (b) the force acts backward. facts: the train is accelerating at a constant at a constant forward direction...the ball is dropped and will continue to move...

DocAl to the rescue. Hello again DocAl. I have inertial issues! I will re-read my on-line tutorial. Anyway, let's begin. 2.) The horizontal force is equal to the force acting on the car to keep it moving at a forward, constant velocity. With that in mind I select answer (c.) there is a...

Thanks ColdRifle. I assume that the quotes you posted with the answers below are the correct answers. Is that right? If so then I just missed one of the first seven questions. I did not think that I did that good. Now, for question #6. I do not understand. You say the answer is d.) 150%...

Thanks to everyone who have viewed my threads and helped me understand some basic physics concepts better. I passed my first on-line certification on a basic physics module. I am now proceeding to Module 2. I have complete the first section and I am working on the assessment questions. My...

I was thinking about this last night. Tell me if I am off in my thinking. This rotating ball would fly off at a 90 degree angle to the tangent line (is this the line formed from the center of the circle and extending to the ball). This would make the angle that you are asking me about 90...

I am afraid to answer but NO - the object does not move in the direction of the force along the string...does it?

What have you decided to do in the lab experiment? If you have a younger audience a bucket full of water that you spin around in a large circle using your arm is dramatic. Of course the force and momentum of the water in the bucket will keep it in the bucket and not spilling out when the...
