Part of it is relative motion.
a=dv/dt=d/dt(dx/dt)=d^2x/dt^2Is the rate of a tangent to the slope of a graph signifying velocity versus time. It is a snapshot of acceleration at a precise moment in time based on the relative changes in velocity over time. It is the limit of acceleration for any given point within the displacement vector.Instantaneous acceleration is how fast a velocity is changing at a specific instant.
Position is a vector and displacement is also a vector. The difference is that, position describes a specific point relative to a reference point and displacement is the straight-line distance and direction from one point to another.
relative acceleration between two bodies in motion is the vector substraction of the acceleration of that bodies.
Normally displacement means that some distance has been travelled. If you want to get picky, you can say that is you travel in a closed path, the displacement is zero. In such circumstances, when multiple movments are being combined, one makes is clearer by saying that combining several displacements gives the "net displacement." To get even more picky, we can point out that displacement is a vector defined by the separation of two points. The direction of the displacement vector is the direction of the second point relative to the first and the magnitude of the displacement vector is the magnitude of the distance between the two points. So, since displament is a vector and a vector can have zero length, one can say that you have a zero vector of displacement when no distance has been traveled.
Acceleration and time are relative. Acceleration = Change in Velocity/Time taken
Displacement describes the distance between two points in space, and the direction of this distance relative to either of the two points. Velocity describes the rate of motion, per unit time, for any instant during the travel between these two points. ie. How fast an object traveled. Velocity must also describe the direction of travel relative to either of the two points.
That's going to depend on 'relative' to what ?Relative to the acceleration of gravity on Earth, it's precisely 1.000, or 100% .Relative to the acceleration of gravity on Pluto, it's 16.822, or 1,682.2 % .
When an object's distance or direction from another object is changing, it is called motion.there are a number of possibilities depending on the exact nature of the physics.relative velocityrelative displacementrelative acceleration
Displacement
Speed is the magnitude of velocity, or the rate of change of distance.

Relative acceleration' occurs when there is no increase in momentum (no transfer of energy takes place) and when the increase in density occurs only because an object is descending into a denser 'space' in the energy field, resulting in a relative size contraction which creates increased density and a corresponding relativistic increase in the measure of how 'energetic' that energy system has become. The acceleration that occurs and the relative increase in velocity are the results of momentum remaining constant as the spatial gradient of the energy field changes, such that as the clock slows down a relative acceleration occurs.
