Moving Objects slow than the actual speed

[disney]

Thanks for Julio Jerez's great work!
but, In the whole newton demo ,I found the speed of moving Objects is no more fast than 10% of the actual speed,such Freefall
why ?

[Julio Jerez]

what? They move accoding to the Gravity wich is 10.0 in all demos.
In the SDk demos object are large so the speed look slow, but is is correct.

when you use aprpriate sizes in and rreal application the illutions of motion looks right.
