Explore Newton’s Laws of Motion and the physics of dynamics. Learn how Isaac Newton’s Principia explains the forces, acceleration, and rules governing movement.

Newton’s laws are more than just homework problems; they are the transition into the modern era of science, where observation and cause-and-effect became the way we understand our existence.
Freshman level Newton’s Laws of Motion








Newton’s Laws of Motion are a foundational set of three rules that describe how the physical world works. First introduced by Isaac Newton in his 1687 book, Principia, these laws provide a roadmap for understanding how forces cause objects to move. They apply to everything in the universe, from a bird in flight to a satellite orbiting the Earth, serving as the essential starting point for anyone studying physics.
Kinematics focuses on the description of how objects move, specifically looking at factors like velocity and acceleration. Dynamics, however, dives deeper into the actual forces that cause that motion to happen in the first place. While kinematics might describe the path of a leaping dolphin, dynamics explains the underlying physical rules and forces that govern every inch of that jump and the resulting movement.
For students and freshmen just starting to learn physics, Newton’s Laws of Motion act as a fundamental roadmap for the entire universe. These simple yet universal principles explain the "why" behind movement, moving beyond simple observation to the core mechanics of dynamics. Understanding these laws allows beginners to grasp how forces and motion interact in everyday scenarios, such as a box sitting on a floor or complex planetary orbits.

"I never knew where to start with nonfiction—BeFreed’s book lists turned into podcasts gave me a clear path."
"Perfect balance between learning and entertainment. Finished ‘Thinking, Fast and Slow’ on my commute this week."
"Crazy how much I learned while walking the dog. BeFreed = small habits → big gains."
"Reading used to feel like a chore. Now it’s just part of my lifestyle."
"Feels effortless compared to reading. I’ve finished 6 books this month already."
"BeFreed turned my guilty doomscrolling into something that feels productive and inspiring."
"BeFreed turned my commute into learning time. 20-min podcasts are perfect for finishing books I never had time for."
"BeFreed replaced my podcast queue. Imagine Spotify for books — that’s it. 🙌"
"It is great for me to learn something from the book without reading it."
"The themed book list podcasts help me connect ideas across authors—like a guided audio journey."
