Circular Motion
To move a more massive object in a circle, do you need more or less force?
More force!
What number will be the SAME in your x-dimension equation AND your y-dimension equation?
Time! (t)
Where is g=9.8m/s2 valid?
on the surface of earth
Where does "Centripetal Force" point?
Towards the center of the circle!
If an object is shot sideways, and at the same time another object is DROPPED, which will hit the ground first?
Same time! (They both start with 0 speed in the y-dimension)
Where is G=6.67*10-11 valid?
Anywhere in the universe!
What happens if the "Centripetal Force" suddenly vanishes?
The object flies off in the same direction.
How do you split an initial speed into x- and y- components?
vx = v cos theta
vy = v sin theta
If you DOUBLE the distance between two objects, what happens to the gravity force between them?
It becomes ONE-FOURTH of what it was.
