Does a spiral staircase have a constant slope? Why?
Only straight lines have a constant slope, curves don’t. A normal staircase has a constant slope (if you ignore the steps), so does an escalator. But not a spiral staircase (it’s not straight, is it?). It’s slope is different at different points along it. A slope or gradient is actually the steepness. A slide has a constant slope, but a roller coaster track does not, because the coaster keeps moving up and down, round and round. Why is it that when you’re at the top, you start screaming… because you know it’s very steep there, and you’re going down with a very high velocity (umm or acceleration… I’m not gd at Physics lol). It isn’t steep at the bottom is it? If it’s going along a straight line, like a train, you dont scream at all, because the steepness, or slope there is zero. But when it’s vertical, the slope is infinity… That’s really really really really really reallllllly steep, so you start screaming. So horizontal lines have zero slope. Vertical lines have slope = infinity
