simple example : the real world like when bullet hits a wall and when debris is falling, the big chunk will fall faster (air can't hold it) while the smaller debris just need to float before hits the ground. So i want to simulate the real world where the bigger mass will 'easily' fight air resistance as its force (f=ma) is bigger so the air don't have enough energy to stop them. and since the g is constant and no v0 (initial velocity) then the V will be the same -> in ideal world bigger and smaller fall the same, the only different is the energy need to stop them. in ideal world v(speed) is not affected by mass, but by acceleration (a) or in this case gravity (g). I'm not trying to simulate the ideal physical world, but real world. So far i can think only to create multiple particle system with different 'drag' value then combine those particles systems. Is it any parameter to set to handle this task ? The idea is to have different 'drag' effect to each particles where the bigger the particle, the smaller the 'drag' will affect it or in simple word : the bigger particle will easily fight air resistence so it will fall faster. How can i simulate so the bigger particle will fall faster than smaller particles. In Blender, i have a particle system with random size of particle element.
