The equation F = ma is one of the most important in physics. Yet we have so far not explained how to get a quantitative operational definition of either mass or force. Somehow, from this one ...

Understanding this relationship between mass and force is crucial for grasping the fundamental concepts of motion in physics. By appreciating their roles, you can delve deeper into how objects move ...

Newton's laws of motion, often perceived as abstract, are actually evident in everyday experiences. The first law explains inertia, demonstrated by seatbelts in cars. The second law, F=ma, clarifies ...

When you think of space missions, you might think of humans walking on the moon or rovers rolling around on Mars. But there's a whole bunch of other awesome space missions too. One of these events was ...

Speaker one We’ve been using Sir Isaac Newton’s theories for hundreds of years and still use his equations today. Now, how can we test Newton’s second law using equipment found in our laboratory?

Friction is a force that always opposes motion. Force is measured in newtons (N). A force is a push or a pull. Contact forces arise between two objects which are in contact. Non-contact forces act ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This helps, sort of, but as more numbers get thrown around, it can get ...
