In a free fall the velocity of a stone is increasing equally ion equal intervals of time under the effect of gravitational force of the earth. Then what can you say about the motion of this stone? Whether the stone is having: (a) Uniform acceleration (b) Non-uniform acceleration (c) Retardation (d) Constant speed answer fasttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt

Answer»

ANSWER:

UNIFORM ACCELERATION (OPTION A).

Explanation:

WHEN A STONE IS DROPPED FROM A CERTAIN HEIGHT THE VELOCITY INCREASES AT 9.8 M/S DUE

GRAVITATIONAL ACCELERATION OF 9.8 M/S^2

AND IT CONTINUES TO BE IN ACCELERATED MOTION TILL IT TOUCHES THE GROUND AND VELOCITY AND ACCELERATION BECOME 0.

YES IT IS IN UNIFORM ACCELERATION COZ ITS VELOCITY IS INCREASING AT THE RATE OF 9.8M/S

IN EVERY SECOND.
