What is Distance traveled: Definition and 176 Discussions

Distance is a numerical measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). The distance from a point A to a point B is sometimes denoted as




{\displaystyle |AB|}
. In most cases, "distance from A to B" is interchangeable with "distance from B to A". In mathematics, a distance function or metric is a generalization of the concept of physical distance; it is a way of describing what it means for elements of some space to be "close to", or "far away from" each other.
In psychology and social sciences, distance is a non-numerical measurement; Psychological distance is defined as "the different ways in which an object might be removed from" the self along dimensions such as "time, space, social distance, and hypotheticality.

    Shortest distance along the shore and into the lake

    Attempt : I copy and paste the problem as it appeared in the text below. To be sure, of course the man cannot swim directly to B for minimum time of travel. He should run a distance (##x##) to some point D along the shore and then swim to B. I draw those details in the diagram to the right...

    Solving Distance Traveled Using Formulas vs. Graphs

    So basically I wonder why the distance traveled by a body in the 5th second gives different results when calculated by the formula for accelerating body(##d=V_0\times t + \frac{1}{2}\times at^{2}##) and when calculated using a graph(formula for the surface of the triangle). Here is the graph of...

    I Distance traveled by a ball down a ramp and on a flat path

    Question: A ball is hit with a certain force and it starts with an initial velocity of V m/sec decelerating due to friction along a flat path and then up an inclined ramp coming to stop at the top of the ramp where the ramp becomes flat again (as per diagram A). The total distance traveled along...

    How does tire pressure affect distance traveled by a bicycle coasting to a stop?

    How to calculate distance traveled if you know a(v) graph equation?

    I know that you can find the distance traveled by integrating v(t), but I can't find a way to convert a(v) into it. I tried derivating and integrating the a(v) equation, but I don't know what the results mean.

    A rolling ball, find distance traveled

    I figured the best way to do this is to focus on the second half of time. We can use the information there to find acceleration and that should make it fairly simple to find distance traveled in the first 5 seconds. Average speed in 5s-10s I found to be 40m/s. My problem is that to find the...
