Kinematics Part 2

1. Understand the formula for calculating mean and how to interpret it:

   1. The mean is calculated by adding up all values and dividing by the number of values. It represents the average value of a set of data.

2. Be able to describe how to maximize vertical height and horizontal displacement by modifying the throwing technique:

   1. To maximize vertical height, one should increase the release height and release angle while decreasing the initial velocity.

   2. To maximize horizontal displacement, one should increase the initial velocity while maintaining a low release height and release angle.

3. Understand the key elements of the throwing technique in shot put or other throwing events:

   1. Key elements of the throwing technique include the windup, entry, transition,

4. Understand how modifying elements such as release angle, release height, and velocity can affect vertical height and horizontal displacement:

   1. Modifying release angle, release height, and velocity can affect the trajectory of a projectile and therefore, the vertical height and horizontal displacement.

   2. Increasing the release angle and release height can increase the vertical height while decreasing the horizontal displacement.

   3. Increasing velocity can increase the horizontal displacement while decreasing the vertical height.

5. Understand which projectile motion variable that horizontal displacement is most sensitive to:

   1. Horizontal displacement is most sensitive to initial velocity.

6. Be able to discuss coaching techniques used to optimize horizontal displacement (in terms of biomechanical variables):

   1. To optimize horizontal displacement in throwing events, coaches can focus on improving the athlete's technique and mechanics.

   2. Coaches can work with the athlete to improve their body position, arm angle, and release angle.

   3. Body position should be stable and balanced, with the athlete's weight shifted onto the back foot during the wind-up and onto the front foot during the release.

   4. Arm angle should be kept at about 45 degrees during the wind-up and then extended fully during the release.

   5. Release angle should be optimized based on the athlete's individual strengths and weaknesses.

   6. Coaches can also work on increasing the athlete's strength and power through strength training and plyometric exercises.

7. Know how an athlete’s height and strength can affect their shot putting performance:

   1. An athlete's height and strength can affect their ability to generate force and momentum in the throwing motion.

   2. Taller athletes may have an advantage in generating more force due to their longer lever arms, but shorter athletes can compensate with good technique and explosive power.

   3. Stronger athletes can generate more force and therefore greater momentum, but athletes with less strength can compensate with good technique and efficient movement patterns.

8. Understand how an athlete's body composition and technique can help compensate for limitations in height or strength:

   1. An athlete's body composition and technique can play a key role in compensating for limitations in height or strength.

   2. Athletes with shorter heights may benefit from a lower center of gravity and more explosive movements to generate greater force.

   3. Athletes with less strength can focus on improving their technique and mechanics to generate more efficient movement patterns and generate more force.

   4. Proper technique and mechanics can help athletes of all sizes and strengths optimize their performance in throwing events.
