Why parachutists do not fall with constant accelerating motion?

Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.

Explain why parachutist and snowflakes donot fall with a constantly accelerating motion?
The parachutist and the snowflakes do not fall with a constantly accelerating motion because the velocity changes.
Which term refers to the speed at which a falling object stops accelerating and begins to fall at a constant rate?
terminal
Which term refers to the speed at a falling object stops accelerating and begins to fall at a constant rate?
Terminal Velocity
What term refers to the speed at which a falling object stops accelerating and begins to fall at a constant rate?
The speed is called "terminal velocity".
How do free fall parachutists control their speed?
By adjusting their cross-sectional area - i.e. by curling up or spreading out.

Does free fall occur only when air resistance does not affect the motion of a falling object?
Yes, unless speaking about parachutists who refer to free fall as falling through the air without opening their parachutes.

What might parachutists do to speed up their rate of fall?
They would have to reduce friction by becoming perpendicular to the ground and reduce their surface area.
What is plummet mean?
for something to fall at an accelerating rate.
If you jump up in a moving object why do you fall in the sameplace?
The answer is based on Galilean interial frames. If you are standing on a (non-accelerating) platform moving at a constant velocity, it is physically identical to standing on a still, non-moving platform. The sum of the forces acting on you (remember force = mass x acceleration) is the same in both cases.
What do you call the motion of an object with a constant acceleration?
Free fall. Airbus has built aircrafts that may dive with an acceleration of 9.81 m/s2 to simulate zero gravity. satellites are technically in a constant free fall. A world where no friction would occur would lead to constant acceleration as long as the force acting on the object stays the same.
Is free fall balanced or unbalanced?
An object in free fall is accelerating, so the forces on it must be unbalanced.
What is the acceleration of a falling object that has reached it's terminal velocity?
Since the direction of the motion remains constant throughout the free fall, once the speed also becomes constant, the acceleration is zero.
