Does uniform negative acceleration properly characterize the motion of a heavy object thrown violently downward from a tall building?
The largest variation from two objects moving downward either 'dropped' or 'thrown' thereby allowing earth's natural gravity to increase until an object approaches and/or reaches maximum velocity. The difference in the two examples, 'dropped' or 'thrown' objects merely illustrates that the "thrown" object will reach maximum velocity quicker than the 'dropped' object.
What else can I help you with?
Describe how the velocity and acceleration of an object change as it fell from tall building?
The magnitude of the velocity will increase. The velocity will be downward - and since it increases, the acceleration will be downward. The acceleration doesn't change (it will remain constant at about 9.8 m/sec2), unless air resistance becomes significant.
How does the elevator's acceleration change when it is moving downward?
When an elevator is moving downward, its acceleration changes to be negative, meaning it is slowing down.
What is the downward acceleration of a thrown object in projectile motion?
The downward acceleration of a thrown object in projectile motion is constant and equal to the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. This acceleration acts vertically downward and affects the vertical motion of the object while the horizontal motion remains unaffected.
When riding in an elevator why does a person appear to lose weight when accelerating downward?
Weight is felt by the body resisting the pull (acceleration) of gravity. Less acceleration means less pull thus less weight. The rate at which you are accelerating downward subtracts from the pull of gravity, thus your weight is less. If you fall, say from a cliff or tall building you accelerate downward at exactly the acceleration of gravity so you're completely weightless.
What is the downward acceleration of projectile that is released from a missile accelerating upward at 9.8?
The downward acceleration of the projectile released from the missile would still be due to gravity, which is approximately 9.8 m/s^2 on Earth. This acceleration is independent of the initial upward acceleration of the missile.
Does uniform speed properly characterize the motion of a heavy object thrown violently downward from a tall building?
No. Regardless of its initial speed, the object still experiences downward acceleration at the rate of 'G'.

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.

When an elevator is moving downward, its acceleration changes to be negative, meaning it is slowing down.

Is acceleration due to gravity always downward?
Acceleration due to gravity is always directed towards the center of the Earth, which is typically considered downward. However, in certain situations such as on a curved surface or in space, the direction of gravity's acceleration may vary.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
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?
The acceleration of the object would still be g downward, regardless of the angle at which it is thrown upward. The acceleration due to gravity always acts in the downward direction towards the center of the Earth. The only difference would be the horizontal component of the velocity due to the initial angle of the throw.
What is the acceleration of falling body at 0.5 seconds?
acceleration of a falling body is 9.8m/s*s and its direction is vertically downward.
When a ball is thrown upwards is there any change in its acceleration all throughout its motion?
Yes, the acceleration of the ball will change. Initially, the acceleration is downward (due to gravity) while the ball is speeding up. As it reaches its peak height, the acceleration becomes zero. On the way back down, the acceleration is again downward and the ball speeds up due to gravity.
