Use the fact that the only force needed to keep an object in circular motion at a constant speed is a centripetal force, F_c, which points towards the center of the circle. But if the speed of the object is changing, then there must also be a force in the direction of motion, which...
since the object is getting no closer to this central point since the radius r is fixed. Think of centripetal acceleration as a free-fall in which there is no danger of the object hitting the ground, because the force drawing the object toward it (...

I don't actually solve theorems and solve mathematical problems. You need effort, in a sense, a second time in the sense that whatever skill you have, you have to apply that skill in order to create tangible achievements. [00:23:41] And for many things like doing math or writing or ...
To move in a circle, a force is needed with its direction focused on the center of the revolution. This force is called the centripetal force. The acceleration produced by the centripetal force is called the centripetal acce...

Each employee has different sources, different family backgrounds, different social abilities and different abilities. Therefore, the difficulties that need to be resolved are diffe...

How to measure momentum? Why the first law of motion is called the law of inertia? What can affect the strength of gravitational force? What affects the magnitude of gravitational force? How do you solve for angular momentum if the inertia is not given but the angular velocity is?
I know it's a lot of variables (plan is to reduce via forward variable selection). But even know it's a lot of variables they're either int or Factor; which as I understand things should just work with a glm. However, every time I try to fit this model I get: ...
