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, ...

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 ...

1. For the total mass of each glider, calculate the value of 1/mass. For example, 100 g has a mass of 0.1 kg. The value of 1/mass is 1/0.1 = 10 /kg. 2. Plot a line graph with acceleration on the ...

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 ...

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 ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...

You've been sheltering in place for weeks now, and you could really use some more fun physics puzzles to solve, am I right? Don’t panic. All the physics problems you can imagine are right here on the ...
