1. 1. What is the relationship
between spring
compression and distance
traveled?
A. The farther the distance
traveled, the more the
spring is compressed
B. The higher the energy the
bigger the bars
C. The more the spring is
compressed, the farther
the distance traveled
D. The more the spring is
compressed, the bigger
the bars
2. What kind of relationship is
elastic energy and
compression?
A. linear
B. nonlinear
3. If the spring could be
compressed 8cm, what do
you think the bar would
like?

2. ReviewReview
• Elastic energy
• Factors that affect EPE:
• Material
• Stretch length
• Non-leaner relationship

3. Energy TransferEnergy Transfer
• Energy TRANSFER is the
passing of energy from one
object to another object

4. The total energy before the collision is equal
to the total energy after the collision.

5. Energy TransferEnergy Transfer
• The transfer of energy is also
called work
• Work is done when a force
moves an object a measureable
distance

6. Energy TransferEnergy Transfer
•No movement = no work
•Work = Force x distance

7. Energy TransferEnergy Transfer
• Power- is the rate of doing
work or
• The rate of transferring energy
or
• How fast or how slow energy
is transferred
