The three strata of study within the study of kinesiology are:
1. Core scientific domain: the core scientific domain deals with the sub disciplines that are found in kinesiology. Examples of these sub disciplines are biomechanics, sport medicine, exercise physiology, history of sport and dance, neurophysiology of performance, physiology of sport, sociology of sport, etc.
2. Sociocultural based form of movement: this aspect of kinesiology deals with the different types of games, sport and dance that are practised in different cultures and countries. The aspect studies expert skills that are involved in different sociocultural based movements. Examples of sociocultural based movements are aquatics, combative, individual sport, running, etc.
3. Methods in professional application: these deals with the professional training and careers that are available in kinesiology. There are generally five areas of professional training, they are: capacity building, management and administration, performance enhancement, instruction in physical education and research.
A < B < C
C will increase faster than B which is faster than A
Answer:
- <u>The water ballon that was thrown straight down at 2.00 m/s hits the ground first, 0.19 s before the other ballon.</u>
Explanation:
The motions of the two water ballons are ruled by the kinematic equations:
We are only interested in the vertical motion, so that equation is all what you need.
<u>1. Water ballon is thrown horizontally at sped 2.00 m/s.</u>
The time the ballon takes to hit the ground is independent of the horizontal speed.
Since 2.00 m/s is a horizontal speed, you take the initial vertical speed equal to 0.
Then:
<u>2. Water ballon thrown straight down at 2.00 m/s</u>
Now the initial vertical speed is 2.00 m/s down. So, the equation is:
To solve the equation you can use the quadratic formula.
You get two times. One of the times is negative, thus it does not have physical meaning.
<u>3. Conclusion:</u>
The water ballon that was thrown straight down at 2.00 m/s hits the ground first by 1.11 s - 0.92s = 0.19 s.
Answer: For a total eclipse of the Sun to happen, the Moon must get directly in front of the Sun, as seen from Earth.
Explanation: solar eclipse occurs when something comes between the earth and the sun, casting it's shadow on the surface the earth. For the the sun to be blocked completely. The obstructing body must come directly between.
