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?

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 ...

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 ...
