A homerun is hit by Ryan Howard, it flies about
375 feet.
Another homerun is hit by Chase Utley, it flies
403 feet.
Both players run the bases, and tag home to
score a run. Assume they both ran the same
distance, the balls were pitched at the same
speed and they used similar bats.
Which player did more work to score their run?



Based on the information we have, Chase
Utley worked harder for his run.
Since the distance they ran, the ball they hit
and the bat they swung are the same, the
only difference in work is the amount of force
they put on the ball.
Utley would have had to use more energy to
increase his force.

 If
a Woodchuck could chuck
wood, how much work would a
Woodchuck do, if his power
rating was 20 W and he worked
for 60 seconds?
 How much energy did he use?
TIME’S UP
The answer…
Time x Power =
Work
time
Time x Power = Work
time
60 X 20 watts = ? J
seconds
P = 20 W
Time = 60 seconds
W=?J
So, we have to solve for Work
The woodchuck would
do 1200 J of work on
the wood.
Since Work done is equal to the energy used,
(work-energy theorem) the Woodchuck used
1200 J of energy to chuck the wood.
