How Fast is tennis

Age 7-11 (KS2)
Age 11-14 (KS3)

An interactive resource that uses tennis to introduce the equation Speed = distance/time. Students serve the tennis ball and are asked to calculate its speed, or the time available for a player to reach the net to return a shot. An accompanying worksheet/teaching resource expands on the presentation and includes an outdoor activity for students to measure time and speed

How Fast is Tennis

1In tennis tournaments a radar gun is used to measure the speed of a serve.
The speed of the ball is calculated by measuring how far it travels in a known time.http://teachable.net/res.asp?r=12942We have used geometry to calculate distances on a tennis court How could we use these to calculate the speed of the ball?3Speeds are calculated using the equation:4For example:A man takes 14 seconds to run 70 metres. What is his speed?Speed = distance/time
= 70m/14s
= 5 m/s5In the following slides speed is calculated using horizontal distances on the court.6Shoot!26mTime:Speed = 52m /s0.5 secs7Shoot!Time:24mSpeed = 40m /s0.6 secs8Shoot!Time:25mSpeed = 50m /s0.5 secs9Shoot!Speed:13mHow long does it take for the player to reach the net if he can run 5m/s?Time = 2.6 seconds5 m/s10Shoot!Speed:12mHow long does it take for the player to reach the net if he can run 4m/s?Time = 2 seconds6 m/s11We have learned How to calculate speeds and times using the equation:

How Fast Is a Tennis Match

How Fast Is A Tennis Match?
In his winning match the 2007 Wimbledon Champion Roger Federer hit a serve that had a speed of 216 km/hr!
Tennis tournaments use radar guns to measure the speed of a serve. These record the distance travelled by the ball in a known time. Speed is calculated using the equation:
Convert 216 km/hr into metres per second (m/s)
.........................................................................................
Convert 216 km/hr into miles per hour (mph)
.........................................................................................
A tennis ball is hit from the bottom left corner to the top right corner of a tennis court. It takes 2.0 seconds. Calculate the average speed of the ball.
(Base line = 11m; Side line = 24m)

......................................................................
......................................................................

......................................................................
A tennis ball is hit down a side line on a tennis court. The average speed of the ball is 40m/s. Calculate the time taken for this shot.
