gravitational acceleration is the acceleration due to the force of gravity (your weight).
Newton's second law is F = ma, as this can be rewritten for Weight (the gravitational force) as W = mg where g is the gravitational acceleration.
On Earth g = 9.81 m/s/s.
If you traveled to a different planet it would change as the force of gravity would be different thus the gravitational acceleration would be different (on the moon it is 1.6 m/s/s on mars 4 m/s/s on Jupiter 25 m/s/s)
Acceleration is a change in velocity.
16 ft./sec./sec.
In a theoretical scenario with constant velocity, the true acceleration would typically be zero.
No. Gravitational force is the pull an object experience from gravity. Gravitational energy is the energy an object has from its position in a gravitational field. An object moving up in a gravitational field gains gravitational energy.
Gravitational energy Potential energy
When the 1000 kg are at rest, on Earth with gravitational accelleration 9.81 m/s2, 1000 kg equal 9.81 kN
Acceleration is a change in velocity.
Yes.
Retardation is the application of a force that produces negative accelleration. Synonyms would be braking, decelleration, damping, etc. Gravitational force operates downward (in a negative direction) so, in most frames of reference, gravity is a retarding force.
acceleration has everything to do with gravity
Local accelleration or gravitation creates force. Mass remains constant despite presence or absence of accelleration or gravity.
Going back to the equation F=m·a you can see that if the force changes but the mass does not, accelleration will change as well. If mass and force do not change, accelleration will be constant.

accelleration
When you say initial speed I assume there will be accelleration. If so you could you: s = ut + 1/2at^2. or s = 1/2(u + v)t where s is distance in meters u is initial velocity in ms v is the final velocity in ms a is accelleration in ms^-2 t is time in s If there is no accelleration then s = ut
The rate of change in accelleration.
