what is the meaning of Matthematic Moddel,
focusing on a certain problems will there be some other Matthematic Moddels ?
Can u help me to simulate a ball droping from h in frictionless ari with Matt Modd is
s=1/2gt^2
v=2gh

thank u

I'm kind of confused on what you are asking. We make mathematical models to represent real world things in terms of an equation where we can get definitive answers, well hopefully.

By the way, the standand forms for the position, velocity, and acceleration functions for earth are:

$$s(t) = \frac{1}{2}gt^2+v_{0}t+h_{0}$$

$$v(t) = gt + v_{0}$$

$$a(t) = g$$

That's for dropping something on earth, assuming no friction. You can use "a" as -32ft/sec or -9.8 m/sec.
