WebThe 9.8 m/s^2 is the acceleration of an object due to gravity at sea level on earth. You get this value from the Law of Universal Gravitation. Force = m*a = G (M*m)/r^2. Here you use the radius of the earth for r, the distance to sea level from the center of the earth, and M is the mass of the earth. WebA point mass is an idealization of a real solid body. It possesses mass, but its demensions are assumed to be so small that its location can be sufficiently accurately defined by the … Web将 最大穿透速度（Maximum Depenetration Velocity） 设置为非0值时，速度绝不会超过该数字，这样会更稳定，但代价是对象仍在穿透。. 接触偏移乘数（Contact Offset Multiplier）. 创建物理形状时，我们将其边界体积的最小值乘以此乘数。. 数字越大，接触点就越早生成 ... prep double coated fleece for spinning
