Suppose you have a cylinder on an ramp and you let it start rolling down. What will be its acceleration? Great question, right? I like this because it brings in many different concepts in introductory ...

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, ...

For the total mass of each glider, calculate the value of \(\frac{1}{\text{mass}}\). For example, 100 g has a mass of 0.1 kg. The value of \(\frac{1}{\text{mass}}\) is \(\frac{1}{0.1}\) = 10 /kg. Plot ...

It doesn't seem like such a difficult question, but it always brings up great discussions. If you drop a heavy object and a low mass object from the same height at the same time, which will hit the ...
