Organisms in a Food Chain
food chain, a linear depiction of energy flow, with each organism
feeding on and deriving energy from the preceding organism.
Each feeding level in the chain is called a tr

I. Stress and strainMost of the objects we have discussed so far have been
considered to be rigid, as in they do not change shape when respondi
Forces and Newtons Laws
I. Newtons First Law: An object in motion tends to stay in motion unless
acted upon by an outside force. An object at rest tends to stay at rest
unless acted upon by an outside

Rotational Motion
I. Rotational kinematicsthe variables/quantities we learned about before
position, velocity, acceleration, are all linear quantities. There are
angular analogues for all of them.

An objects energy is something that quantifies its ability to move or potential to
move. Also defined as the ability to do work.
