# Science of Golf

Courtesy: NBC Learn, the United States Golf Association and Chevron

In connection with the start of the golf season, explore the science of golf, provided by NBC Learn, in partnership with the United States Golf Association and Chevron. In this 10-part series, physics and math become more interesting for students when put into the context of the game of golf. Learn about calculating golfers’ handicaps and golf scoring, the evolution of the golf club and ball, as well as how factors like friction, volume and energy all affect how a golf ball travels.

### Science of Golf: Evolution of the Golf Ball

This segment discusses the transformation of the golf ball from the original wood to leather stuffed with goose feathers, tree sap, and finally today’s synthetic materials. Do you know why golf balls aren’t smooth, but instead have a dimpled surface? Find out in this video how that chance discovery was made, as well as the science behind it. See what is inside of a golf ball, why each material is used, and the guidelines for golf balls in the PGA.

### Science of Golf: Evolution of the Golf Club

Similar to the “Evolution of the Golf Ball” segment, this video explores the design and engineering of golf clubs evolved from handcrafted hardwoods to what golfers use today. Learn about scientific principles such as mass distribution, inertia and acceleration, in the context of carefully creating golf clubs to ensure the best possible force behind the ball. Also, see how golf clubs are tested in laboratory settings to determine their effectiveness, comparing the old-fashioned wood clubs to today’s titanium.

### Science of Golf: Volume, Displacement & Buoyancy

There are strict limits on the volume of golf clubs, but how could that affect golfer’s performance in the game? Find out in this segment why volume of club heads is important, as well as how to find volume using water displacement instead of measurements. Using the video, combine these concepts with inertia to understand how they come together to affect the power behind the golf ball.

### Science of Golf: Calculating a Golf Handicap Index

If you've ever heard the term “handicap” in golf, you know it’s an advantage that players get to even the field. What you may not know is how handicaps are determined. In this segment, explore the reason for the handicaps as well as the mathematics behind determining a player's handicap. Also learn how the averages come into play and how the USGA uses handicaps to encourage players to improve their game.

### Science of Golf: Math of Golf Scoring

Golf is filled with numbers, statistics and math, but how much do you know about the different numbers of golf scoring? In a previous video, we learned about handicapping, but how does that factor into the overall score of a game? Learn about pars, positive versus negative numbers in golf, and aggregated scores in tournaments.

### Science of Golf: Physics of the Golf Swing

This video breaks down the powerful golf tee shot into three major physics concepts: torque, centripetal force, and the double pendulum effect. Learn how the way a golfer’s centripetal force created by their body can affect a golf shot, and what parts of the golfer’s body create the double pendulum. Also explore how the torque of a shot influences the rotation of the ball to create a powerful shot.

### Science of Golf: Friction & Spin

This segment focuses on golf’s short game, using shorter clubs to get the ball close to the hole. Explore how different uses of spin can affect where the ball lands, such as backspin for the ball to stop quickly after landing, as well as how the spin is created by the club. Have you ever noticed the groves on the face on a golf club? Learn why those are included in order to improve the force of friction, which determines the spin of the ball.

### Science of Golf: Kinematics

We've all seen professional golfers "reading the green" when preparing for a putt, but what are they looking for? In this video, learn the science behind the green, including how the friction and slope of the green affects the speed of the ball. Explore how this all comes together in the scientific term “kinematics,” which refers to acceleration, position and velocity to describe motion. This video also explains how professionals measure green speed, as well as the science behind the speed.

### Science of Golf: Work, Energy & Power

An excellent demonstration of the physics concepts of work, energy and power, this video explores the science of putting in golf. Learn about the different types of energy and how it is transferred from the club to the ball, how the amount is work is determined using force and distance, and how much power is used, which is known as how much work is completed over a period of time, all in the context of a putt.

### Science of Golf: Water Conservation

Conserving water resources has become an important concern in recent years. This segment discusses how turf and water conservation specialists educate golf courses superintendents on conserving water at their course. Techniques like capturing rainfall, using recycled water and developing new varieties of turf grass are used to maximize the efficiency of the water that courses use. The video also describes new high-tech tools that courses use to find soil moisture, and some of the factors that affect moisture, such as evapotranspiration.
