	2) ω=r x v/\|r~~\|^2~~, where v ~~represents~~ velocity, and r ~~represents~~ the radius ~~of the circle~~.		2) ω=s/rxt, where s is the arc length, and r is the radius of the circle.
			3) ω=v/r, where v is the linear velocity, and r is the radius.

	Similar to how the velocity is defined as a change in distance over time, acceleration can be defined as the change in velocity over time. Acceleration can be calculated by taking the derivative of velocity with respect to time. If the velocity function was ''v(t)'', then the acceleration at time t would be ''a(t) = v'(t) = f"(t)''. A constant non-zero acceleration means that the velocity is increasing or decreasing linearly. If the acceleration is always 0 and velocity is non-zero, this means that velocity is constant and position is increasing or decreasing linearly.

	The instantaneous velocity can be found by using calculus and taking the derivate of a distance vs time function at a specific point in time. If the position function is ''f(t)'', then the velocity at a time t would be ''v(t) = f'(t)''.
