Air resistance
Due to the air resistance the parachute brings to the object when falling, the acceleration of the object is no longer 9.8m/s which is the acceleration of gravity. Due to the air resistance brought upon the object due to the parachute, the acceleration is limited and capped.
thrusters
Thrusters slow the object down before impact on the ground occurs. This is done by allowing the object to fall towards the ground at the standard gravitational acceleration of 9.8m/s. However, before impact, thrusters turn on, which causes acceleration in the opposite direction, causing the velocity to decrease.
How to create thrusters
Due to thrusters being used to accelerate the object in the opposite area of motion, balloons can be used, which utilise elastic potential energy to push air out, creating a downwards thrust and upwards acceleration.
connect timed rockets to bottom of object (not realistic though)
jet fan (electric to kinetic energy to move air)
shock absorbers
Shock absorbers do not affect the speed at which the object falls to the ground as they do not affect air resistance. Instead of affecting air resistance, shock absorbers ensure that upon landing, the shock in which the object feels is minimised as the shock absorbers absorb the majority of it.
