Displacement,, Velocity and Acceleration  


The displacement of a particle is defined as its change in position in some time interval. Displacement is a vector. A vector represents both a magnitude and a direction. Distance is the length of a path followed by a particle. This is a scalar value. 


On the diagram, the average velocity is the slope of the line connecting the two points of interest. 

What if, instead of the average velocity between TWO points,

The
velocity at any point is the derivative of x wrt t

Acceleration occurs when the velocity of an object changes with time 



acceleration is the change in the velocity which is the change in the position wrt time. acceleration is the derivative of the velocity wrt time and is the second derivative of the position wrt time
