What are the differences between distance and displacement?
displacement is the distance and direction from the starting point to wherever you stopped. distance is how much you traveled to get there. if you went back and forth 20 times that's your distance. that does not effect your displacement in the least.My Answer: Distance is the total length of the actual path between two points. Displacement is the length and direction of a straight line between starting and ending points.and other answer :distancethe actual length or path between two position is a scalar called distance.it is represented by "s" or "D"its dimension is [L]displacementthe shortest distance between two positions in a straight line is a vector called displacement.it is represented by "S" OR "D"its dimension is [L] and it includes a direction
What is the zero point 0 k on the kelvin scale called?
Absolute zero
Does displacement always equal distance traveled?
No. Displacement is how far an object is from its original position. This means that if an object traveled in a circle and returned to its original point, it will have a displacement of 0 while the distance will be whatever the circumference of the circle was. Hope that helps.
Can a displacement from one point to another be zero yet the distance involves in moving these point be zero?
Yes it is possible. Any body that travels in any particular closed shape (circle, square, triangle etc.) and returns to the point in which it started would have travelled a certain distance but the sum of its displacement would be nil. Example: A body travels in a 1 mile north, then 1 mile west, then one mile south and finally 1 mile east (ie. a square). The body has travelled a distance of 4 miles. The bodys displacement is 0 miles due to it returning to the point in which it started. You can calculate displacement using vectors. For this example assuming east is positive x and north is positive y: north + west + south + east y -x -y +x = 0

What is the distance between a point and a line containing this point?
The distance is 0.
Two numbers that are the same distance from 0 but lie on opposite sides of 0 are called of each other?
They are the additive inverses of each other.
Assume that point A on this measure stick represents 0. What is the distance from point A to point B?
0 to 3
How far would 0 and its opposite be on a number line?
they wouldn't have a distance from each other because they're on the same point
What is the distance between the origin and the point (5 12)?
Distance from (0, 0) to (5, 12) using distance formula is 13
What is the definition of distance from point to line?
It the point is on the line the distance is 0. If the point is not on the line, then it is possible to draw a unique line from the point to the line which is perpendicular to the line. The distance from the point to the line is the distance along this perpendicular to the line.
Why are the x and y axes called what they are?
The ordinate is the y coordinate of a point and the abscissa is the x coordinate of a point and both axes intercept each other at the point of origin (0, 0) on the Cartesian plane.
What an integers distance from 0 is?
The distance from 0 of an integer is called its absolute value, or magnitude.
What does a distance vs time graph illustrate?
It illustrates the distance of an object at any particular amount of time from its starting point (when time = 0 and distance = 0).
What is the shortest distance from a point to a line?
10000-40-0-0-1 meter
What is the intersect point called when the x and y axis meet at coordinate 0 0?
That point, (0,0) is called the origin
