PhysicsPhysics (from Greek φυσική (ἐπιστήμη), i.e. "knowledge, science of nature", from φύσις, physis, i.e. "nature"[1][2][3][4][5]) is a part of natural philosophy and a natural science that involves the study of matter[6] and its motion through space and time, along with related concepts such as energy and force.[7] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.[8][9][10]

Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy.[11] Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 17th century, the natural sciences emerged as unique research programs in their own right.[12] Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms of other sciences, while opening new avenues of research in areas such as mathematics and philosophy.

Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products which have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industriali

COMPONENTS OF PFSTT

PFSTT stands for Physical Fitness Sports Talent Test. It is a combination of assessments you undertake to ascertain your level of fitness. The PFSTT is broken down into four elements: Strength tests, speed and power tests, endurance tests, and flexibility tests. Each of these categories are then broken down into several trials. Here is a rundown of what you can expect.

Strength Tests

• The repetition test - This is the benchmark strength test that all sportspeople use.

• Sit up test - This highlights core power. • Press up test - Tests your stamina.

Speed and Power Tests

• 30m sprint - The basic test to measure force. • 30m sprint fatigue - Perfect for high impact sprint sports like lacrosse, soccer and basketball. • Agility test - Again, great for high impact sprint games. • Standing long jump - Measures bursts of power.• Standing Vertical jump - The basic test to measure power bursts. • Hexagon drill - Gauges speed, dexterity and poise.

Endurance Tests

• The 'Balke' 15 minute run - Indirectly assesses aerobic muscle • The 'Cooper' 12 minute run - Much the same as the 'Balke' run.• Shuttle run - Another test for aerobic strength but more suitable for high impact sprint sports. • The Rockport test - Basic walking test for those who are less energetic.

Flexibility Tests

Reliable flexibility tests are few and far between. A device called a goniometer is used to measure the angle at which you stretch and gauges your flexibility.

• Sit and reach test - The yardstick of all flexibility tests. Measures lower back and hamstring flexibility. • Trunk rotation test - Measures the 'twist' in your torso.• Groin flexibility test - As above, but in your groin.
