If the air moves faster below an object does pressure push the object upward or downward?
upward
When an object falls freely the kinetic energy of the object will?
It will decrease if the object moves upward; decrease if the object moves downward.
What happen when the downward pull of gravity on an object is equal to the upward force of water?
The object floats in the water.
Why do airplanes defy gravity?
Airplanes do not "defy gravity", any more than you do when you walk upstairs. In both cases, an upward force is generated that is greater than the downward force of gravity on an object. Since the net force on the object is then upward, the object accelerates upward.
Why does a projectile move upwards when thrown upwards even though a force of gravity acts downwards on it?
In the act of "throwing", the thrower imparts an upward velocity to the object, by temporarily applying an upward force to it that's greater than the downward force of gravity. During that brief period, the sum of the forces on the object is directed upward, so it accelerates in that direction. After the throwing ends, however, the only force on the object is the force of gravity, directed downward, so its acceleration is downward. That means that the upward velocity becomes smaller and smaller, until it's zero at the peak of the arc, and the velocity then becomes downward as the object begins to fall from its peak..

A movie is made showing successive frames for an object accelerating downward. If the sequence is run backward would the object accelerate upward or downward?
UPWARD UPWARD UPWARD

It will decrease if the object moves upward; decrease if the object moves downward.

When the upward and downward forces on a falling object or changes its direction is called an?
Terminal Velocity.
The relationship between the upward and downward forces exerted on an object in a liquid is called?
buoyancy
Why did the smoke move first in an upward direction and then a downward direction?
positive air pressure then hit a negative air pressure.

An object is dropped and falls to the ground with acceleration of g if its thrown upward at an angle its acceleration would be 0 larger than g g upward g downward or none of the above?
9.8 meters per seconds squared in the downward direction.
What is faster upward or downward?
it depends on a lot of factors but i would say downwards because you are working with gravity not against it.
