Velocity Lab

During
this test, we were calculating the velocity of a golf ball and a ping
pong ball dropped from three different heights. First, we dropped the
golf ball from about one meter. The meter stick was not exact, so we did
not know if that was going to effect the outcome of the velocity. When
we were calculating by hand, we got a velocity of about 3.3m/s/s for the
golf ball and 2 m/s/s for the ping pong ball. I didn’t think that this
test was going to be very accurate when we did it by hand or with the
motion sensor because we did not really know how to use the sensor and
we couldn’t get exact times from doing it by hand. When we were trying
to time by hand, we were doing it by eye so it was not going to be the
same each time. For the second test at 2 meters, the velocity was again
probably not exact because we only had one meter stick so when we tried
measuring out 2 meters but we were probably moving the stick up and down
so it was not still at the 2 meter mark. The velocity we calculated was
2.8 m/s/s for the golf ball and 3.3 m/s/s for the ping pong ball. For
the third test, there was not enough room to drop the balls from three
meters, so that was not an exact measurement either. Even though the
measurement was not exact, for the velocity we got 3.3 m/s/s for the
golf ball and 3.75 for the ping pong ball. When we were dropping the
balls, the forces they were dropping at were 447.468 for the golf ball
and 24.5 for the ping pong ball.
