Question

Define the following terms and write the SI unite

(a) Displacement, and

(b) Instantaneous velocity.​

Answer 1

Answer:

SI units of the following are

➜( a ) The standard unit of displacement is the meter (m)

➜( b ) The SI unit of instantaneous velocity is m/s . It is a vector quantity. It can also be determined by taking the slope of the distance-time graph or x-t graph.

Answer 2

Answer:

(a) Displacement: It is the shortest distance from the initial to the final position of a point P and is a vector quantity that has a direction.

The SI unit is meter (m).

(b) Instantaneous velocity : Instantaneous velocity is defined as the rate of change of position for a time interval which is very small (almost zero).

The  SI unit is  meter/second (m/s).
