... force needs to exist for Newton’s laws to hold true. Example: Being in a car going around a circular race track. You feel pushed towards one side of the car. You can say that this “push” is some imaginary force rather than the inertia of your body. This imaginary force is called the centrifuga ...

Circular Motion Notes
... Two objects A and B are located on a spinning disk. Object A sits at a radius of 2 meters from the center, while object B sits 4 meters from the center. If the angular speed for the disk (ω ) is 200 rad/s, what are the linear speeds for objects A and B, respectively? ...

Circular Motion
... For the problems from this chapter, you need to recall the definitions of frequency, period, and know how to use the fact that that an object moving in a circle with constant speed has speed given by v = 2πr / T. Note that this is not on your OSE sheet. Perhaps it should be. circumference = 2πr spee ...

... Note that "Centripetal force" is just a fancy name for the radial component of the net force. It is not a new kind of force and is NOT drawn on force diagrams. A net force could have both tangential and radial components; the component tangential to the direction of motion causes the object to speed ...
