Displacement is a vector quantity. This means it has both size AND direction.
Therefore, displacement is defined as distance in a given direction. Rather then simply 'distance'.
Distance itself is a scalar quantity... and only has size. No direction.
20m - Distance.
20m upwards - Displacement.

Actually, single and double displacement reactions are part of a subsection known as the stultus buccu reactions look it up
There are several. They would include displacement, buoyancy, and density.
The slope of that graph at each point is the speed at that instant of time.
Mechanics is a branch of science that deals with the behavior of physical bodies under force or displacement.
Mechanics is a branch of science that dwells on the behavior of physical bodies and how they behave when under force or displacement.
Drought is not a change at all. It is a situation, meaning: dryness, thirst.Draught is neighter a change. It is a displacement of air, wind
The difference between the final and the initial position of an object is called displacement. Unit of displacement is metre . Displacement <= Distance always.
