WebThe original equation describing movement on a line was. s (t) = t³ - 6t² +9t. In this case, there were two times when the particle was speeding up. That would be where the velocity and acceleration are both positive OR both negative in sign. t (1, 2) Time between 1 and 2 seconds. t (3, ∞) Time greater than 3 seconds.

My teacher said electric field can never be negative, it'll either be positive or zero. Online sources pointed out that since electric field is a vector when doing calculation we only report the magnitude. WebAverage speed of a moving body always positive because Distance travels by the body is the total length of the actual path. It depends upon initial and final positions of the body.
