2. Golf and Physics  Based on Physics golf has been trying to determine how much power or energy is required to place the ball successfully.  Golf uses power and force differently than other sports because of the way it requires muscle control and sequential movement.  The concepts on the following slides demonstrate different areas of how physics relates to golf.

3. Force = Mass x Acceleration  Acceleration is caused by an unbalanced force acting on an object.  The acceleration grows as the unbalanced force increases.  Objects with more mass are more likely to resist changing motion from force.  Newton’s second law states:  Force on an object will cause the object to accelerate in the direction of the force.  The acceleration is directly proportional to the force.  The acceleration is also inversely proportional to the mass of the object.

5. Angles and Height  The distance of a golf shot depends related to the loft of the club.  Loft is the angle of the club of the clubface in relationship to a perfectly vertical clubface.  Using a longer golf club causes the angle of loft to be smaller.  The shorter the golf club, the higher the loft angle, the higher the golf balls trajectory and the shorter the golf balls flight.

7. Distance and Velocity  The initial speed of the ball, the angle at which it is hit into the air, and spin on the ball determine the distance that the ball goes.  The distance the ball will travel is determined by the interaction between the golf club and the ball.  Maximum ball distance requires the right combination of initial velocity, initial angle of flight, and golf ball spin.
