Question

what is velocitywhat is displacement ​

Answer 1

VELOCITY :- rate of change of position

DISPLACEMENT :- SHORTEST DISTANCE BTW INITIAL AND FINAL

Answer 2

Here is the answer :

Displacement : It is the shortest distance between the final and initial points,

The only possible shortest distance between 2 points is a line segment joining them,

So basically, The displacement is the length of the line segment joining the initial and final points in the motion.

The length of line segment can easily be determined if you are dealing displacements in coordinate systems, But when it comes to a non coordinate system, You have to assign your own origin and generalize your coordinates.

Also,

Displacement is a vector meaning, The line segment we take should always be directed from initial to final point that is the line segment needs to be a directed line segment, Or simply an arrow.

units : meter.

Dimensional formula : [L]

velocity :

it is the rate of change of displacement.

For heavy displacements in heavy time,

Velocity (v) = ∆s/∆t, this can also be used for average velocity.

For instantaneous velocity,

Lim (∆v/∆t) = dv/dt

∆t-->0,

Velocity is also a directed line segment just like displacement.

Units of velocity : m/sec²

Dimensional formula : [L T^-1]
