Talk:High School Physics/Energy

Don't mean to be rude, but I started editing this article because there were several misuses of there/their/they're. Soon I found some bizarre sentence constructions followed by an unfortunate volume of... content errors. I found this article while looking for some common equations used in high school physics.

If people want to make contributions, please do some research. Research isn't plagerism, copying the way people explain things or example problems is plagerism, but if you don't know what you are talking about, or really don't feel like doing the work to find the right answers, please don't post. In this case "someone else will do it" might be the right way to think about it.

It makes sense why so many teachers are becoming frustrated with wikipedia and are more frequently discouraging students from using it for reference.

I think the content of this page would be better viewed by nobody. It is a mix of weak information out of context without reference or explanation... and that only applies to the good parts.

Darren Baird (physics teacher), Toronto ON writes... I agree, this article is an awkward attempt at being "cool" or "engaging". The first paragraph vaguely recalls Venus Flytrap in WKRP in cinninati teaching about the structure of the atom.

The article is rife with errors...
 * Kids, it is joules not jeules (the SI unit of energy)
 * Wave energy is a type of mechanical energy.
 * The equation for potential energy varies on how it is stored... for example spring potential energy is PEspring=0.5kx^2, where k is the spring constant that depends on the stiffness of the spring and x is how far the spring is stretched. Gravitational potential energy is simplified as PEgrav=mgh where m is mass, g is the acceleration due to gravity and h is the height of the object above a reference height. IF PE=0.5mv^2, then would not this formula require a velocity... if the object has a velocity then you would say that it is moving and therefore it has "actual" rather than potential energy?

I still stand by Wiki... It is 90% of the time a good start point to get an overview. These bad articles give our students a chance to practice discriminating between good and bad information.

Thanks Mr. Baird.
