WebSince the velocity vectors always point in the positive direction, the velocity is always positive. The car starts with a large, positive velocity which gradually declines until the velocity of the car is zero at the end of its motion. Determining the acceleration from a motion diagram WebVelocity and speed are often confused, but they are very different. We define the average speed as the distance traveled divided by the time it takes to travel it. Distance is step size times the number of steps, irregardless of direction. Speed is a scalar value and is always positive or zero. Average Speed = distance / time cinta terlarang chord the virgin

How come speed is always positive, but velocity can be negative?

WebAverage speed is a scalar, so we do not include direction in the answer. We can check the reasonableness of the answer by estimating: 5 meters divided by 2 seconds is 2.5 m/s. Since 2.5 m/s is close to 2.9 m/s, the answer is reasonable. This is about the speed of a brisk walk, so it also makes sense.
