Billion Air

• Tiger wood is super hero golfer.
• He is so famous that he earns billions of dollar.
  
• Why people crazy about Tiger wood because he is
  the best.
• He has unbelievable record on his long shot and
  many other unbeatable records. This is so famous
  people even published game for him.

Physics involvement

• How can he hit the ball to have a distance of
  over 300 yard.
• The amazing hit distance can be explained with
  idea of physic.
• The golf operates with principle of torque, which
  is perpendicular the force times the length of
  the lever arm.

Archimedes

• The concept of torque originated with the work of
  Archimedes on levers.
• Archimedes was an ancient Greek mathematician,
  physicist and engineer.
• His name is not widely spread and known today,
  but he was one of the leading scientists in the
  past. He is credited with designing innovative
  machines. He explained the principle of the
  lever.

Torque

• The force applied to a lever, multiplied by its
  distance from the levers fulcrum, is the torque.
• TrxF
• r is the particle's position vector relative to
  the fulcrum
• F is the force acting on the particle,
• or, more generally, torque can be defined as the
  rate of change of angular momentum,
• TDL/DT
• L is the angular momentum vector
• t stands for time.

Torque Application

• if a person places a force of 10 N on a spanner
  which is 0.5 m long, the torque will be 5 Nm,
  assuming that the person pulls the spanner by
  applying force perpendicular to the spanner.

7
Torque Application

• If a force is allowed to act through a distance,
  it is doing mechanical work. Similarly, if torque
  is allowed to act through a rotational distance,
  it is doing work. Power is the work per unit
  time. However, time and rotational distance are
  related by the angular speed where each

• revolution results in the circumference of the
  circle being traveled by the force that is
  generating the torque. This means that torque
  that is causing the angular speed to increase is
  doing work and the generated power may be
  calculated as
• Power torque x angular speed

Torque Application

• Tiger Woods can hit the ball about 341.5 in the
  British Open 2005
• Tiger Woods swings the club about 120 miles per
  hour.
• The actual speed of swing is slower 120 miles per
  hour but his swing times the club length makes it
  possible.
