When you are sitting on a rock what force acts on you?
-- The force of gravity of your bottom against the rock, in the downward direction. -- The 'reaction' force of the rock against your bottom, in the upward direction. Since the forces are equal in magnitude and opposite in direction, their vector sum is zero. Some would describe this situation as "The forces on your bottom are balanced." In any case, the 'net' force on your bottom is zero, and your bottom therefore does not accelerate.
Within the forces in flight identify the forces that work against each other?
The two basic forces that counteract each other when referring to Flight are: The WEIGHT of the object in flight and The LIFT FORCE on the bottom of the wings.
What forces are pushing up on a still car?
"Normal" forces push up on a still car. In this case, normal forces are equal in magnitude but opposite in direction to the gravitational forces pushing down on the still car.
When a book sits on a shelf what force if any does the shelf exert on the book?
The shelf must exert an upward force on the book that is exactly equal to the book's weight. If the forces on the bottom of the book were not balanced (did not add up to zero), then the bottom of the book would be accelerating.
What forces do not cause a change in momentum?
Any internal forces. Also, any external forces that add up to zero.
Why does sucking on a straw make the liquid come up?
When you suck on a straw the pressure at the top of the straw becomes lower than the pressure at the bottom, which forces liquid up.
Why hasn't James Cameron's company figured out the double bottom was completely broken off at the surface as the Titanic exerted twisting forces as well as straight up and down forces as it broke?
because they are too dumb
Which type of forces is exerted on the bottom row of bricks in a building?
compression
What is top down or bottom up?
bottom-up
Where do you drill holes in barrel that holds sump pump?
Normally on the sides close to the bottom and other times on the bottom of the tank so hydraulic forces do not lift the tank up ALL depends on the situation at hand there is no set of rules as far as I know

What is more prefer bottom-up or top down?
bottom-up
What happend to forces when thing speed up or slow down?
Nothing happens to the forces. The forces are what makes the thing speed up or slow down.
When was From the Bottom Up created?
From the Bottom Up was created on 1995-01-10.

What do the message at the bottom of the flag?
The message at the bottom of the flag is to serve our country.
