If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?

The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2

How does the weight of a falling body compare with the air resistance it encounters before it reaches terminal velocity?
The weight exceeds the force of air resistance, but as the speed increases the air resistance increases, so the net force (weight - air resistance) falls. When the difference becomes zero the acceleration ceases and you have terminal velocity.
How does the weight of a falling body compare with the air resistance it encounters after it reaches terminal velocity?
If its speed of fall is no longer changing, then its acceleration is zero. That tells you that the forces on it must be balanced, so the upward force of air resistance must be exactly equal to the downward force of gravity.
How will the electric field strength compare at a 2 m distance point charge?
I don't know. You've neglected to mention what it's to be compared to.
Compare and contrast speed and acceleration?
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
How do acceleration and deceleration compare each other?
They both have to do with cake. When you accelerate you eat more cake and when you degenerate you eat less cake.
Why resistance is neglected for fault finding?
A fault can be resistive in nature, and the amount of resistance in the fault is unpredictable. It is unusual for a fault to be inductive or capacitive, so a typical method is to determine the impedance to the fault, and compare only the inductive part of this to the inductive part of the line impedance.

How does car's acceleration compare to a free falling object?
1g, 9.82 m s^-2, gives a 0-60 (mph) time of 2.73 seconds, from rest, assuming negligible air resistance. Not many cars can do that.
Compare the sizes of forward force and air resistance while a car is moving at 30mph?
when a car is speeding up how does the forward force and air resistance compare
Why armature resistance is less than 1 Ohm?
why armature resistance is very low as compare to field resistance in dc motor
Compare velocity from acceleration?
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
Compare the tension of a train with constant speed and acceleration?
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
How does the acceleration of gravity compare between objects?
Acceleration due to gravity is the same for EVERY object on the earth, at the same altitude. The only thing that differs is the effect other forces have on it. For instance, in a vacuum, a feather and a bowling ball will both fall at the same rate. However, in normal air, the feather will be impeded by air resistance, so will fall slower.
How does the force of gravity on a raindrop compare with the air drag it encounters when it falls at a constant velocity?
If the vertical speed is constant, that means there is zero vertical acceleration. If the vertical acceleration is zero, that means the net vertical force on the object is zero. If the net vertical force on the object is zero, that means the downward force (weight) and upward force (air resistance) are equal.
When forces are balanced compare the acceleration of an object at rest and an object in motion?
An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.
How does acceleration due to gravity of the large ball compare to the smaller ball?
If you let two balls fall, initially the velocity will be the same. A small (and light) objects will eventually fall slower, because of increased air resistance. But if you can ignore air resistance - distances are short, or you do the experiment in a vacuum - acceleration will continue to be the same - on Earth, about 9.8 (meters per second) per second.If you let two balls fall, initially the velocity will be the same.
