If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
-- The force of gravity is unchanged before and after.-- The force of air resistance on the skydiver is greater before, and less after,because she is falling slower after the parachute opens.-- The effect on her of air resistance is greater after the parachute is open. Theincreased air resistance itself acts on the parachute, and its effect is transferredto the skydiver through her harness.
If air resistance can be neglected, there is no effect. If there is air resistance, the general tendency is for more massive objects to fall faster. In places like the moon, where there is no air, a feather and a rock fall together.
Air resistance has no effect on gravity. The force of friction due to air resistance against a falling object balances part or all of the gravitational force, depending on the object's shape and speed through the air ... just as your hand or a rubber band attached to the object would ... but the full force of gravity is still there.
Your question describes it as a "falling body", so I'm assuming that you're asking about a body with no force on it except for the gravitational force. This is an important assumption. If it's true, then the mass (weight) of the falling body has no effect at all on its acceleration. Except for the effect of air resistance, all bodies fall with the same acceleration.

is when you get near the heat to an object like plastic bottle it will be get milted an a seconds only
because they arnt biodegradable so wont break down.

perfectly constant acceleration? Hypothetically, virtually infinite speed? A few things
All objects, under these conditions, will accelerate at the same rate as they fall. (Note: Just the fact that you can call it a "falling" object is one of the effects of gravity.)

Neglecting the effect of air resistance, the speed of any falling object ... including ice cubes ... is always 32.2 feet per second greater than it was one second earlier.

Absolutely,Although the effect will be minimal if you drop the quarter from waist height.If you drop it from an airplane, it might even reach terminal velocity where the air resistance would counteract and balance the acceleration due to gravity.
