How did the formula of uniform curve motion come from?
According to one of the four basic formulas of kinematics: v-v0=2ax.

2ax=V2? -V 1? 2a(x/2)=V(x/2)? -V 1? Two-way synchronization, with V2? -V 1? =2V? -2V 1? , so there is V(x/2)= white ((V 1+V2)/2) under the root sign.

Speed is a physical quantity indicating the speed of an object, which can be represented by the symbol V. In the International System of Units (SI), the main unit of speed is m/s, which is read as meters per second. Commonly used units are km/h, m/min, etc.

The formula s=vt cannot be mathematically understood as the speed of an object's movement is directly proportional to the distance and inversely proportional to the time. Uniform linear motion is characterized by constant instantaneous speed and direction and zero acceleration, which is an idealized motion.

The speed of an object moving in a straight line at a uniform speed remains unchanged, so if you know the speed at a certain moment (or a certain distance), you will know its speed at any moment or any moving point.
