Centrifugal force

Game Engine Game Engine Support and Discussion

Does the blender physics engine calculate centrifugal force?

For example, if I biking game where the player is taking a sharp turn, centrifugal force should cause the player to speed up.

Does blender do this? (Or any tips on how to program it in Python?)

no

#3

bummer. Any ideas on how to do it in Python?

strange physics you have there.

are you sure ?

Yeah, those physics are correct. Its like riding a manual pallet jack. :smiley: But I dont think that it is something you would want built into the physics. The more the engine has to do itself the more problems you will encounter. I would just develop a script to speed up the rider when turning.

#6

you don’t speed up

and cintrifugal force doesn’t exist, what you feel is inertia

see, to turn you have to change direction. you accelerate [sideways] by being pushed on by the road, but this doesn’t really make you go any faster

#7

Like I said. You propel with sideways force because of the force like riding a pallet jack. If you stand on a pallet jack and turn the handle side to side (turning the wheel back and forth) you propel yourself forwards. Its just like holding a bike by its seat and steering it back and forth by leaning it back and forth. This also propels the bike forward. But its such a small force that IF you wanted it in your game (for perfect realism) you would put it in with a script or something. Not to count on the physics engine which is already flawed (and by flawed I mean not nature).

yeah riding pallet trucks is great fun unless the manager catches you and gives you the h&s crap

#9

:smiley: Now thats hilarious. My managers would have races with me! :slight_smile:

Thanks so much for your help. I’ll add a little speed when turning.

Or I might ask my Calculus teacher for help.

Thanks again! I’m a newbie at this.

I thought centrifical force was when say a person was spinning with an object in his hand, and he suddenly let go of that object and it would go in a straight line…

No. The object is already going in a straight line unless acted upon by an external force. “Centrifugal Force” is how people desribe the force that “throws” the object out. In reality, centrifugal force doesn’t exist. There is a centripetal force that acts to change the objects path from a straight line to a curve.

…and no, there is no force that speeds up objects that are turning. The pallet jack example uses a force called friction to move it.

I would ask your physics teacher for help.
