Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
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.
When a rockets lifts off the ground the net force is in an upward direction Is the upward pushing force greater or lesser than the downward pull of gravity?
Greater
When a rocket lifts off the ground the net force is in upward direction. Is the upward pushing force greater or lesser than the downward pull of gravity.?
Greater
What is the value of g in upward direction?
Since gravity causes objects to fall downward, rather than upward, I would describe the upward force of g, at the surface of the Earth, as -9.8 meters/second2.
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
How do you change notes on a tuba?
You can change your notes on the tuba by moving your lips upward or downward. Upward is lower, downward is slightly higher than upward and just stright means high.
Can you convert a downdraft to an updraft?
You must change the direction of the air flow, This is done by converting the downward pressure upward. You either need to use a forced air fan to change direction of the downdraft or to divert the air that normally flows downward into an upward motion by causing the downward air to be diverted into upward air chambers forcing the air upward. WindKat cowls has come up with a pretty good idea for solving this problem with chimneys. They say it is the most anti-downdraft cowl on the market. You can find them on the Web.
What is the magnitude of a force of 117.4 moving upward and another force of 74.1 moving downward?
the magnitude is 43.3 and the direction is upward.

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

Why balls reduce speed when it ascends higher?
As a ball goes up, the force of gravity is acting on it. The force of gravity means that acceleration in the upward direction is negative (and thus positive in the downward direction). The upward velocity of the ball decreases until it reaches zero - then ball begins to descend with increasing downward velocity.
