You read in class, "How Soccer Can Help Us Understand Physics". Once it is in motion, what does an object like a soccer ball have a natural tendency to do?

• It has a natural tendency to slow down.
• It has a natural tendency to stop.
• It has a natural tendency to change directions.
• It has a natural tendency to keep moving.

Swimmers wearing full-body suits that reduced underwater friction were able to swim faster than other swimmers. What evidence from the passage supports this statement?

• Some swimmers shaved their entire bodies to reduce friction caused by hair and increase their speed.
• After losing contests by a tenth of a second, some swimmers started ridding their bodies of hair to reduce friction.
• Swimmers wearing full-body suits swam at the same speed as swimmers wearing shirts and shorts that clung closely to their skin.
• Swimmers wearing full-body suits began to break world records and started winning all the races.
