Polymers have significantly improved tennis equipment like racquets, balls, and court surfaces. Modern tennis racquets utilize strong yet elastic nylon strings instead of natural gut. Tennis balls now contain a rubber core made of polyisoprene instead of leather, improving their durability and performance. Additionally, outdoor tennis courts often incorporate polyethylene and polyurethane in their construction for durability and performance.

are used in your sport?
● Need a tennis ball
● A tennis racquet
● Tennis shoes
● Tennis court

3. A tennis ball and a tennis
Racquet
● They use a tennis
racquet to hit the ball
to other side of the
court, going back and
forth.
● The tennis ball is
used to bounce the
ball back and forth
until a player misses.

4. The evolution/history of the
tennis racquets
● The first tennis racquets
were actually the
players hands and
gloves to hit the ball.
They then evolved into
wooden paddles. In the
14th century they had a
racquet with strings with
a wooden frame. One
hundred years later new
improvements in
technology they had
laminating the
technology on the
racquets.

5. Polymers have improved
● The natural “gut” string is the
important characteristics of
strength, resiliency and
surface roughness. The
improved string is in the form
of a filament of polymer
material which is nylon. The
result is a racquet string of
improved stretch resilience,
or resilience under tension.

6. The evolution/history of tennis
balls
● The tennis balls were
made of leather,
stuffed with hair or
wool.
● Now they are made
from rubber and felt
that increases the
ball's wind resistance
and control.

7. Polymers improved in tennis balls
 Leather was the
first material used.
 Now the polymer,
polyisoprene are
used in the tennis
ball cores.

8. Research the football field/outdoor
track and how polymers were
important.
● On the football field
there are polymers
which are
polyethylene and
polyurethane are
included in the
construction of similar
football/track fields
around the world.
