Question

give examples to distinguish a) distance and displacement( b) speed and velocity (c) acceleration and retardation

Answer 1

a.distance=you have to go 25 km more to buy a car.
displacement-you have to go 25 km more in West direction from here to buy a car.
b.the car is going in 23km/h-speed
the car is going in 23 km/h in North direction.-velocity
c.the car get started -accelsration
the car applied a break-retardation
hope my answer helped you.

Answer 2

hey!!
here is ur answer
a)distance - the actual path travelled by the body is called distance.it cannot be negative or zero
displacement-the path followed by the bodybis called displacement.it can be negative,positive or zero
b)speed-distance travelled by the body per unit time is called speed.it only be positive
velocity-displacement travlled by the body per unit time is called displacement.it can be positive,negative or zero
c)acceleration-final velocity-initial velocity per unit time is called accelration.
retardation-when accleration happen in againstvthe force it is called retardation


hope ir helps u
