Why don't all objects fall to the earth at the velocity even though the acceleration due to gravity always stays the same?

The air resistance for objects of different shapes causes a force which accounts for this. A leaf is a good example of an object with large surface area. A parachute - before and then after it is opened it another example.
In a vacuum, such as on the Moon, all objects do fall at the same speed. One of the Apollo astronauts dropped a hammer and a feather at the same time; both reached surface together. Maybe you can find a YouTube showing this.

Why don't all objects fall to earth to the same velocity even though the acceleration due to gravity always stays the same?
because of the differences in air resistance.
What is the acceleration at highest pointn when ball is thrown straight up?
The acceleration is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.
What indicates the acceleration of an object?
Velocity. A change in VELOCITY will always indicate the acceleration of an object.
When is acceleration due to gravity positive and when is it negative?
Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
Is it possible for an object in freefall to have no acceleration?
No, but it is possible to not have an increase in speed. Because velocity is a directional quantity, not a scalar one, an object in freefall (by definition within a gravity field) is always under acceleration, just not necessarily one that alters its speed or even its position. Objects in orbit around a planet are in freefall (hence weightlessness) where the tangential component of their forward motion opposes the pull of gravity.
Why don't all objects fall to the earth at the same velocity though the acceleration due to gravity always stays the same?
because of the differences in air resistance.
What would happen to an object in free fall?
The velocity in the x direction would be constant because gravity only affects the vertical components of objects. The velocity in the y direction would increase due to the constant acceleration due to gravity. The acceleration due to gravity on Earth is always -9.81 m/s^2.

Is the acceleration due to gravity always pointing vertically downward even for an object whose velocity is vertically upward?
Acceleration only depends on the direction of the applied force and is independent of the velocity of the object, so gravity is always pointing down.
What is the acceleration at highest pointn when ball is thrown straight up?
The acceleration is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.
Does gravity always change the velocity of objects?
Only until they hit the ground or the floor.
Can an objects acceleration increase if you drop it from a higher altitude?
no, acceleration due to gravity is always the same, although air resistance might affect it
