Physics equation for speed
WebbWhen the object has moved a complete circle, the value of circumference divided by the traveled time period t will give the value of tangential speed. Mathematically, Vt = (2*π*r)/t We can also find the tangential speed if … WebbIn this formula, v_ {avg} vavg is the average velocity; \Delta x Δx is the change in position, or displacement; and x_f xf and x_0 x0 are the final and beginning positions at times t_f tf and t_0 t0, respectively. If the starting time t_0 t0 is taken to be zero, then the average velocity is written as below:
