the length of a perpendicular segment from the point to the line
The point that is equal distance from the endpoints of a line segment is the midpoint.
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.
The length of the line segment BB' is equal to the distance between point B and point B'.
It is going to look like a somewhat of a quadratic parabola.
Not necessarily. Distance is the total length of the path traveled, while displacement is the direct line from the starting point to the ending point. Displacement can be less than, equal to, or greater than distance depending on the path taken.
It is a point on the number line, at a distance equal to x, to the left of 90.
Distance and displacement can be the same only if an object moves in a straight line from its starting point and the displacement is measured along that line. In such cases, the magnitude of the displacement is equal to the distance traveled.
Yes.
The distance is 0.
That's the torque due to the force.
The volume or weight of a fluid displaced by a floating body (as a ship) of equal weight
The distance covered by a body will be equal to its displacement when the body moves in a straight line without changing direction. This occurs when the body moves from one point to another point in a straight path, as the distance covered will be the same as the displacement between the initial and final positions.
