An object moves in a circular path with constant speed v. (a) is the velocity of the object constant? (b) Is its acceleration constant?

Question

aaronq · Answer

Acceleration is constant but velocity changes because it's direction changes.|dw:1411742597946:dw|

If the gravitational force on an object is directly proportional to its mass, why dont objects with large masses fall with greater acceleration than small ones?

aaronq · Answer

while the force is proportional, it's acceleration is dependent on the mass of the object.

$a=\dfrac{F}{m}$

anonymous · Answer

can you explain it further? :)

aaronq · Answer

Look at the formula, the force is decreased by the mass. So while a force between two large objects is large, the acceleration (and thus the rate of falling) is decreased (by being divided) by the mass of the object in free-fall.

You can plug some numbers in as an example up there.

I have to get going, watch those vids! while you wait for someone else to come help
