Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

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 ...

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?

Isaac Newton's First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." What, then, happens to a body ...

As the New Horizons spacecraft is approaching Pluto, it's getting some great shots. The animation below shows Pluto and Charon as they orbit each other. When a planet (or dwarf planet) has a satellite ...

Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

How do we know the mass of a planet originally appeared on Quora - the knowledge sharing network where compelling questions are answered by people with unique insights. Answer by Geoffrey Widdison on ...

N ot so long ago, had I been asked to free associate with the letters M, F, and A, I would have conjured the words “mass,” “force,” and “acceleration.” After all, as a math professor, I talk about ...
