Using a one-dimensional number line to visualize and calculate distance and displacement. Created by Sal Khan.
Speed Distance Time – Formula. Speed, distance and time are all related by the formula, s = \dfrac {d} {t} where s is speed, d is distance, and t is time. You can rearrange this formula to find the other two, for example, if we multiply both sides by t and divide both sides by s, we get, t = \dfrac {d} {s}
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up. For example, lets say you drive a car. You drive it 5 miles east and then 3 miles west.
When you describe distance, you only include the magnitude, the size or amount, of the distance traveled. However, when you describe the displacement, you take into account both the magnitude of the change in position and the direction of movement.
1 pt. What is the equation to calculate distance? distance = speed/time. distance = time/speed. distance = speed/distance. distance = speed x time.
