    But how many kW per second does it do.

    Free fall under the influence of gravity means the force is 1g.

    Depends... if you mean when he's in free fall, then yes it's 0. If you mean when he hits the ground because his parachute failed to deploy... well, the g-force of that sudden deceleration is pretty hefty :)

    For sky-divers the term "free-fall" includes descending through the air at constant speed, and the force felt is 1 G of aerodynamic drag, opposing gravity.

    That's almost 3times the G force felt by a Tuba player in a marching band!

    The sense of associating the product with a cool item ....

    Perhaps they meant that, but they said "during freefall". (EDIT: However, this is the only answer that makes any sense.)

    And a force 3 times greater than that means this is one dangerous motorbike!

    By that logic, an astronaut orbiting the Earth experiences slightly less than 1g, yet we refer to that as a 0g situation.
