Originated from a game played off the coast of Scotland
First played during the 15th century
Influenced by Kolven from Holland and Chole from Belgium
Changed from hitting pebbles to hitting golf balls
Golf History
![Page 3: Physics of Golf](https://reader035.vdocuments.us/reader035/viewer/2022081503/56813f8d550346895daa7c2e/html5/thumbnails/3.jpg)
Golf ball and club are only main objects in motion
People do not move around a lot
Main focus on golf ball and it’s flight
Objects in Motion

Average Speed
Speeds may vary depending upon the player and golf club
Speed = Distance/Time
Speed = 175/8
Speed = 22.22y/s

Acceleration
Important because it determines the distance of the shot
Acceleration is a change in speed or direction
Accel. = Change in Velocity/Time
Accel. = 22.22/8
Accel. = 2.78y/s/s

Momentum
Momentum = Mass*Velocity
Momentum = 45.7*22.22
Momentum = 2.06g*y/s

Newton’s 1st Law
A body at rest stays at rest unless acted upon by an outside force.
Golf ball doesn’t move until hit and doesn’t stop until air resistance, gravity, and friction stops it.
A body in motion stays in motion unless acted upon by an outside force.

Newton’s 2nd Law
Explains how force, mass, and acceleration are related
Force equals mass times acceleration.
Mass of the golf ball times acceleration of golf club equals distance ball will travel
![Page 9: Physics of Golf](https://reader035.vdocuments.us/reader035/viewer/2022081503/56813f8d550346895daa7c2e/html5/thumbnails/9.jpg)
Newton’s 3rd Law
For every action there is an equal, opposite reaction.
When the club hits the ball the club exerts a force on the ball, and the ball exerts a force on the club

Forces of Golf
Tip: Don’t hit the ball into the water.
Forces: Gravity, friction, speed, velocity, momentum, and acceleration.
Balanced Force
Unbalanced Force
His feet are a balanced force because the ground is pushing up with the same amount of force as his feet are pushing down
His club is an unbalanced force because the force exerted on the ball is greater than the force exerted on the club

Weight Classes?
Weight doesn’t really matter in this sport,
however it’s helpful to be in shape
![Page 12: Physics of Golf](https://reader035.vdocuments.us/reader035/viewer/2022081503/56813f8d550346895daa7c2e/html5/thumbnails/12.jpg)
Friction
Friction is a force which opposes motion
Friction is undesirable when you don’t hit the ball far enough and want it to keep going but it stops
Friction is desirable when you want the ball to stop

WorkThe work equation is: Work = Force*Distance
Work = 2*5798
Work = 11,596 foot-pounds
Work = 2*4
Work = 8 foot-pounds
Work is performed by simply walking a golf course
Work is also done by swinging a golf club
![Page 14: Physics of Golf](https://reader035.vdocuments.us/reader035/viewer/2022081503/56813f8d550346895daa7c2e/html5/thumbnails/14.jpg)
PowerThe power equation is:
Power = Work/Time
Power = 11596/4
Power = 2899 Watts
The amount of power exerted from walking an 18 hole golf course
The amount of power exerted from swinging a golf club
Power = 8/1.38
Power = 5.80 Watts

Machines In Golf?
A golf club is a simple machine
It is a 3rd class lever
![Page 16: Physics of Golf](https://reader035.vdocuments.us/reader035/viewer/2022081503/56813f8d550346895daa7c2e/html5/thumbnails/16.jpg)
Kinetic-Potential EnergyThere is maximum potential energy at the top of the backswing
Potential energy is converted into kinetic energy when the ball is hit
The maximum kinetic energy happens right before the ball is struck

Golf An Exercise?
While it’s true golf is not the best exercise, it is still an exercise
The typical person burns 396 calories playing golf for one hour
![Page 18: Physics of Golf](https://reader035.vdocuments.us/reader035/viewer/2022081503/56813f8d550346895daa7c2e/html5/thumbnails/18.jpg)
Golf On The Moon?
If you were to play golf on the moon, the ball would travel a lot farther because the moon has 1/6 the gravity as on Earth.
It would also require less effort, because there is less resistance as you are swinging.

Ways To Improve Your Game
Understand how momentum, acceleration, and speed can improve your swing
Understand how exerting a stronger force on the ball, while still controlling the shot will increase distance
Practice, practice, practice
