What is the pullback energy similar to? What
else can you think of that bounces back?
ELASTIC POTENTIAL ENERGY
The energy stored in a deformed
object,
for objects that have the tendency
to return to original shape

THERMAL ENERGY LAB REVIEW
3 factors determine the amount of thermal energy in a
substance
Type of substance – Different materials can hold more or less
thermal energy. The more it holds, the slower its temperature
changes.
Kettle gets hot fast!
– hold less thermal
Water slower to
heat – holds more
thermal
Mass of substance – More Mass = More particles holding energy
Temperature of substance

WHAT IS DEFORMATION?
The transfer of KE to thermal
energy causes a change in shape
of substances (visible in soft
substances)
SOUND
Organized movement of particles
– Turns to thermal energy once
organization is lost
