Hey,
Im making a snowboarding game. I'm using Coulomb's equation for friction:
Ff = coef_of_fric * normal force
This gives me the size of the frictional force. But how is the direction calculated? Is it the opposite of the direction of the velocity of the snowboarder? Or is it the opposite direction of the force applied on the snowboarder, gravity in this case. I thought the latter would have been the correct answer. However, when a snowboarder is moving along a flat surface, the force due to gravity is canceled out by the normal. Though the snowboarder is still moving, so there is still some friction. I think I might be missing a force, or vector or something somewhere...
Can someone help me please?f
