PS3B - Conservation of Energy and Energy Transfer

Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between objects with different temperatures. He explains how heat is transferred via conduction, convection and radiation. A teaching progression K-12 is also included.

You are also doing a great service to self-learners by creating these, as they give a solid foundation on which to build their studies. Thanks!

I know you published these years ago, but they are invaluable! Thank you so much!

Hi Paul,
When I computed the work done in pool the white mother ball break the 15ball. The energy brought OUT is more than the energy brought IN. Let’s try to compute.

F = 30lbs approximately; D = 3ft

SOLVE FOR ENERGY IN
W = F X D; W = 30lbs x 3ft = 90ft.lb. ENERGY IN

SOLVE FOR ENERGY OUT
First two ball extreme corner of the billiard ball 2 out of 15 ball
W = F X D; W = 30lbs x 3ft = 90ft.lb X 2ball = 180ft.lb.

The remaining ball (13pcs ball) can produce more than 90ft.lb. so the theory of conservation of energy is misconception.
Appreciated for your reply

Thank you.

Hey Mr. Anderson,  

These videos are great! Although this may sound weird, but can you please make more videos on physics - that would be a great help. Maybe you already have some, but I haven't noticed. 

Thank You

Great if you answer❗
If fields helps to force to transform energy in absence of contact between two objects then, how the energy transformation takes places in case of magnetic field which acts perpendicular direction to Force?

Think and comment if you get that❕

damn, i touched the flame now my finger is conducted :D

They try to transfer our spiritual energy from us as well. I do not give anyone permission to transfer my energy or my children to anyone.
