Is there any consistent way to calculate how long it would take for point B to reach point C? Local radius = adventurer.position:Distance(self.In these equations, we mean that the particle has position x0 and velocity v0 at time t = 0; it has position x and velocity v at time t. Write an equation in standard form when you're given two points on a line. A very common type of periodic motion is called simple harmonic motion (SHM). A system that oscillates with SHM is called a simple harmonic oscillator. If there is no acceleration, we have the formula: s=vt where s is the displacement, v the (constant) velocity and t the time over which the motion occurred. Rotational motion is the circular motion of an object about an axis of rotation. We will discuss specifically circular motion and spin. The instantaneous velocity is mathematically is v.
