I was just about to mention curvature of a hill...
If the hill is a ramp, with Constant slope, then for the time that the car is moving on a ramp with a constant slope then the acceleration is zero..
But if the hill doesn't have a constant slope, or if you are thinking of before the car starts...
Heat Deflection Coatings?
Hello all...
I was wondering if there was anything I could readily use as a coating for piston heads that will reflect the heat, such as ceramics or something that could be done at home?
Thanks
sorry for my ignorace... I'm still second year physics, and just really trying to have a FEEL and Intuition for Physics...lol...
Also a lot is based on the fact that c is a constant... but some physicist contend this... that c may not be constant, and Einstein might be wrong
I'm really not...
Photon Mass Zero?
Ok right to the point, I've learned that a Photon since it is moving at c has a mass zero, but yet I've also heard that with a sensitive enough scale, that you can measure the force of sunlight or other light as photons...very small force, but still a force
A measureable...
