#### Transcript of Projectile Motion in Badminton.

Projectile Motion.
The point of this exercise is to identify and explain the three aspects of projectile motion while using them to analyze and give points to improve a clear shot in badminton.
"Projectile motion is motion under the influence of gravity" (Davis, 2002).
when an object is hit, thrown or launched its path is determined by projectile motion.
three factors of projectile motion: angle of release, height of release and speed of release.
Height of Release.
Height of release is the height from the ground that the object is launched.
All badminton shots require correct height of release to be effective.
Speed of Release.
Speed of release aspect in projectile motion is speed in which the object is released from object applying force to it.
Speed of release is highly vital to most badminton shots to attain required effect.

Angle of Release.
Angle of release is the measurement of the angle as the object leaves the outside force acting on it.
Correct angle of release is vital to maximizing effectiveness of many different shots in badminton.
Optimum angle of release for most objects is around forty five degrees or sometimes less.
"As most implements in sport are released at a height above the ground, the optimum angle at release is somewhat less than 45 degrees" & that "The actual ideal release angle can depend on the technique and physical attributes of the athlete" (Wood, 2010).
Image below shows an attempted defensive clear. Ideal defensive clear "Has a high and deep trajectory" (Badminton Information, 2012)
Ideal angle of a defensive clear slightly less than 45 degrees. To improve clear shot angle of release would need to be increased from 32 degrees to at least 40 to 42 degrees to become an effective clear (Badminton Information, 2012).

Height of release "Affects the trajectory of the projectile and, for a given speed of release and angle of release, the horizontal displacement increases as the height of release increases" (Oxford, 2015).
Height of release in image below is 281.21 centimetres. release point of this height results in a longer distance due to the extra air time given to the shuttlecock.
Makes the height of release aspect of this defensive clear effective.
Only slight improvements that can be made would be a straighter arm to completely maximize height of release.
Speed of release is calculated by dividing distance travelled by time taken to travel the distance.
Speed of release in the image below is 30.67 metres per second, or 110 kilometres per hour - not uncommon for new player.
For defensive clear the speed of release is moderate - point of a defensive clear is to go far while giving time to get into position for another shot.
Speed for this clear however was not enough and did not reach the back corners as desired.
To improve shot speed of release must be faster - means that more power should be put into shot.
Summation.
Overall, applying the three factors of projectile motion to the defensive clear shot shows that many changes can be made to improve it. In the previous three images shown the shot required more power for greater speed of release and a larger angle for angle of release to improve the quality of the it. The three factors of projectile motion are an important part of bio mechanics and play an important role in the efficiency of badminton techniques.
