Centripetal Force
... • Weight & mass are related, but they are not the same. • Mass stays the same but weight changes as the location the object is in changes. • You weigh more on Earth than on the moon because the gravity decreases yet mass remains the same. ...

... If the object is traveling at a constant speed, draw the dots equally apart from each other. If the object is accelerating, draw each dot a little farther apart than the last one. If the object is decelerating, draw each dot a little closer to the last one. Depending on the direction of motion, the ...

... Vector Nature of Angular Quantities • We can treat both ω and α as vectors • If we look at points on the wheel, they all have different velocities in the xy plane – Choosing a vector in the xy plane doesn’t make sense – Choose vector in direction of axis of rotation – But which direction? z ...
