This new 10-part series continues to explore the physics and math behind the game of golf. Provided by NBC Learn, in partnership with the United States Golf Association and Chevron, students will 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.

It is a well-recognized fact of the sport: golf balls have dimples. The lesser-known information is the reason they are produced that way, which is related to aerodynamic drag, also known as wind resistance. The change in airflow because of the impressions in the ball creates air disturbance and allows the ball to fly farther.
Newton’s first law of motion, the Law of Inertia, and second, which explains the idea of acceleration, are crucial to all aspects of the golf game. From the moment of impact between the club and ball, the flight of the ball, to the bounce and roll of a golf ball when it lands, both laws are at play to explain how the force applied to the ball produces its’ flight path.
Every golf swing relies on potential and kinetic energy in order to move the ball. Potential energy is the energy an object has because of its position or capability to move. Potential energy can come from chemical energy in a golfer’s muscles that allow them to swing a golf club. Kinetic energy is the energy of an object in motion, encompassing the motion, heat, and sound released when a golf ball is hit.
The mechanics behind a golf swing are crucial to a golfer’s ability to hit the ball straight and with the proper amount of power. Torque and moment of inertia are they key physics concepts behind this goal. The golfer’s body applies torque to their own body, the club, and finally the club head, which results in how the ball is hit.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
