What would happen to a hot air balloon if the uplift and gravity forces were the same?
If the sum of the vertical forces on an object is zero, then the object moves vertically at a constant speed (which could be zero, or any other constant number).
Why does the speed dcreses when an object is thrown vertically up?
whyh does the sped decreases when an object is thrown vertically up
What is a fired thrown or otherwise propelled object?
a projectile?
A vertically launched object When is the acceleration due to gravity greater when ascending from the top or descending?
As long as the object stays somewhere near the surface of the earth, the acceleration due to gravity is constant, whether the object is moving up, down, sideways, or not moving at all.
What is the equations of motion for an object thrown vertically upwards?
You can any of several formulae for constant acceleration, found in any physics textbook. Acceleration due to gravity is about 9.8 meters/second2.

How is air resistance is force?
It requires a force to propel an object through air, because of the air resistance. Normally, if there were no air resistance and the object were being propelled on the level with no friction, a constant force would accelerate the object steadily. However, it would require a steady force to propel the object through air even without acceleration. And the faster it went the more resistance it would meet.
When an object reaches terminal velocity what is the net force acting on the object?
When an object is at terminal velocity, the two forces due to gravity and drag are equal, so the object ceases accelerating. Its motion is constant and vertically downward.

An object propelled into the air but has no power to keep itself in the air?
A projectile.
What is vertically symmetrical?
to feflect an object so the reflected object is the right way up
If the mass of an object does not change a constant net force on the object produces a constant what?
F=ma, if F is constant and m is constant, then a is constant... its acceleration.
What 2 ways are weight and mass different?
Mass is the amount of matter an object has. Weight is actually a measure of the force of gravity on an object. An object normally has a constant mass, but weight varies with gravity. An object in space will have no weight, but still have the same mass.
Why don't you do any work when you carry an object art a constant velocity?
Well, if you do that for a while, you could certainly raise a sweat, and you would say that you've done a lot of work. But in the strict Physics definition of "work", none of it has been done to the object you carried. The strict definition is: Force acting through a distance. Referring to the object you carry: -- You don't move it vertically. You just hold it there against the force of gravity, but your vertical force doesn't move it up or down. So no work is done vertically. -- Horizontally, the speed is constant. No force is required to maintain a constant speed, so no work is done horizontally either.
