(I am new to this community. If this is off-topic, please let me know and I will close immediately!) I was watching a Veritasium video on YouTube regarding the novel solution to the Einstein field equations and how the singular solution at the Schwarzschild radius perplexed researchers at first. ...

This is a pretty basic question and it's pretty self-explanatory. I was working on homework and I had to list what kinetic energy depends on. Interestingly, it turns out it's also based on mass, not only speed. Does anyone have an explanation? Thanks!

I had to do an online simulation in class, and for some reason an object with twice as much as another rolled down a slope at the same speed of the other object. In other words, objects with a large difference in mass still rolled down the slope at the same rate. Is this correct, first off, or wa...
