god is not a physical being, has no physical limits,where does he reside,and in what form? what about us,humans,are we created in his form? what demintion is godly? the cosmos that we can see shows only physical forms of matter. There are unseen forces that we can messure. Are these godly charaistics? a spiritual deminsion because it is unseen by physical sight. Do we understand non-matter deminsions, pure energy physics?

My physics book, in the section on conservation of energy, says that energy cannot be created or destroyed. The book doesn't provide much of an example except for dropping a pen to the floor. The pen and the floor have a slight rise in temperature. If energy cannot be created or destroyed, it sounds to me like it has no beginning or end. So, if you didn't create the energy when you picked up and dropped the pen, where did it come from? After you drop the pen to the floor, there is a slight rise in the temperature of them both. Is this heat the energy? If so, where does it go when the heat is gone? I'm confused. This is my first class on physics.

In the javelin throw at a track-and-field event, the javelin is launched at a speed of 28 m/s at an angle of 39° above the horizontal. As the javelin travels upward, its velocity points above the horizontal at an angle that decreases as time passes. How much time is required for the angle to be reduced from 39° at launch to 17°?
