The Science of Baseball at T-Mobile Park

Explore the fascinating intersection of engineering, science, and baseball!

Welcome to our exploration of the science behind baseball, where we uncover the physics behind every pitch and engineering behind T-Mobile Park.

Don’t miss our Curiosity at Home resources, which bring the wonders of sport science and more straight to your living room!

Science is for everyone, and STEM is everywhere! The Mariners and their iconic ballpark serve as a prime example of how sports and STEM intersect, driving progress and pushing boundaries in America’s favorite pastime.

The Physics of a Baseball Pitch 

Let’s dive into the fascinating physics behind a baseball pitch, starting with the forces that act on the ball.  

But first, what exactly is a force? A force is a push or a pull that can make an object move, stop, or change direction. 

Starting from the beginning of a throw, a baseball moves forward when the pitcher applies a force to the ball by throwing it. 

Newton’s first law of motion tells us that unless something pushes or pulls on it, the ball will keep moving in a straight line. But when it’s in the air, there are things pushing and pulling on it. These forces—like weight, drag, and lift—work together to shape its path. 

Drag is the air resistance pushing against the ball’s motion. Meanwhile the weight of the ball is being pulled downwards by gravity, while lift is an upward force that can make the ball rise as a result of how it’s spinning.  

The stitches on the baseball can disturb these forces, making the ball move in tricky ways, like the famous knuckleball that wiggles around unpredictably.  

Scientists employ sophisticated tools such as wind tunnels and high-speed cameras, along with conducting experiments, to gain a deeper understanding of these forces. STEM drives progress by allowing scientists to develop new tools and techniques, pushing the boundaries of our understanding of physics and sports dynamics.

Engineering Excellence

T-Mobile Park, home of the Seattle Mariners, stands as a testament to engineering ingenuity, blending state-of-the-art design with environmental sustainability.  

From its retractable roof, which shields fans from the elements while preserving stunning views of the city, to its advanced lighting and irrigation systems, the stadium embodies the principles of engineering and innovation. 

T-Mobile Park in Seattle, Washington, with its roof open and closed

Did you know? The retractable roof weighs 22 million pounds and spans nearly 9 acres! 

According to the Mariners, the three movable panels are powered by 96 ten horsepower electric motors. They effortlessly glide on 128 steel wheels and can close or open the roof in just 10-20 minutes, weather permitting. Engineered to endure harsh conditions, the roof is self-grounded to prevent lightning strikes and can withstand up to 6-7 feet of snow and winds of up to 70 mph. 

Behind the scenes, a team of engineers and architects collaborated to create a venue that not only enhances the fan experience but also minimizes its environmental footprint.  

Through energy-efficient technologies and sustainable materials, T-Mobile Park sets a new standard for eco-friendly stadium design, showing how STEM can shape the future of sports infrastructure.
