This means the stronger a force pushes on an object, and the lighter the object is, the more it accelerates.Ĭombining these two formulas and rearranging gives us: Here, F is force, m is mass and a is acceleration. To do this, we need a couple more formulas from physics. To simulate springs, we must figure out how to move particles around based on Hooke's Law. The spring constant, k, determines the stiffness of the spring. The negative sign indicates the force is in the opposite direction to which the spring is displaced if you push the spring down, it will push back up, and vice versa. The force provided by a spring is given by Hooke's Law:į is the force produced by the spring, k is the spring constant, and x is the spring's displacement from its natural length. Springs have a certain natural length if you stretch or compress a spring, it will try to return to that natural length. One great thing about springs is that they're easy to simulate. We will then make water particles pull on their neighbouring particles to allow the waves to spread. This will allow the waves to bob up and down.
