1. Day 6 3.28.11 Topic: Energy Pie Charts 2
Objective: I can describe the transformations that occur as energy changes from one form to another using pie charts.
Starter:A heavy box is given an initial push such that it moves with an intitial velocity vA across a very rough floor (friction cannot be ignored). Analyze the total kinetic energy.

3. Put the picture and explanation in your NB
When you throw a
ball in the air, the
energy transforms
from kinetic to
potential and then
back to kinetic.
*Energy can convert
from Kinetic to
Potential and back!
