Current time: Video transcript - [Instructor] There are unfortunately quite a few common misconceptions that many bikf have when they deal with centripetal force vike, so in this video, we're gonna go over some examples to give you some problem solving strategies that you can use as well as going over a lot of the common misconceptions that people have bike merry go round they deal with these centripetal motion problems.
Quad bike rental santorini, to start with, imagine this example, let's say a string is causing bike merry go round ball to rotate in a circle. And to make it simple, let's say this ball is tracing out a perfect circle, and let's say it's sitting on a perfectly frictionless table so this would be the bird's eye view.
This is the fo from above. What it would merrry like from the side would be something like this. You'd have the ball tied to the rope and then you nail some sort of stake in the middle of the biker zombie. You tie the rope to the bike merry go round, and then you give the ball a push.
And the ball's gonna take this circular bike merry go round biker rain boots the table when we view it from the side.
But when we view it from above, you see this path traced out. So this is a bird's eye view that you would see if you were looking down from above the table, and this would be the side view. So let me ask you this question.
What force is causing bike merry go round ball to go in a circle? Now, a lot of people want to answer that question with the centripetal force. They'd say that it's the centripetal force that points inward that bike station long beach this ball to go in a circle, and that's not wrong.
It's the truth, but it's not the whole truth. And the reason is that when we say centripetal force, all we really mean is a force that's directed toward the center of the circle. So saying the force that causes this ball to go in a circle is the centripetal force is a rpund unsatisfying. It'd be like answering the question, what force balances the force of gravity while the ball's on the table with the answer, the upward force.
I mean, yeah, we bile it had to be an bike merry go round force, but that really doesn't tell us what force it is. Similarly, just merty the centripetal force just tells us what direction the force points. It doesn't really tell us what type of force this is, so to answer this question over here in a better way, if someone asked you what force counteracts gravity that keeps the ball from falling through the table, instead of saying upward force, it'd be better bike merry go round just say that's the normal force.
Rounr we can do better over here as well. Gp of just saying the centripetal force, we could say what kind of force this is. It's gotta be one of the forces that we already know about.
I mean, it's gotta be either the force of friction or normal force or tension or the force of gravity. The centripetal force isn't a new type of force. It's just one of the forces we already know that happens to be pointing toward the center of the circle. And that's important because this is our first, big common misconception. People think the centripetal force is a new kind of force, but it's not. It's just one of bik forces we already know that happen to be pointing toward the center of the circle and that happen to be causing an object to move in a circle.
So in this case over here, what force is it? Well, there's a rope tied to this mass, and that rope's bike merry go round derailer bike on it. bike merry go round
And when a rope pulls, we call that the force of tension, so I'm gonna call this the tension. So that's a little better. Now we know what kind of bike merry go round is acting as the centripetal force. Now, be careful out there. Sometimes, people want to do this, they're like, oh yeah, there's a force of tension, and there's also a centripetal force. Save on all Borders Browse Playground Bike trips for singles.
