MOTION UNDER GRAVITY - 1D MOTION
GOLD PACKAGE
A body falls freely under gravity, suddenly if the acceleration due to gravity disappears at a point in its
journey then the body
a) moves with uniform acceleration
b) moves with uniform velocity
c) comes to rest
d) moves with deceleration
If g, is the acceleration due gravity at a depth 'd' and g, the acceleration due to gravity at a heighth from
the surface of the earth (if h=d)
[ ]
a) , >
b) g, <g
c) g. = 8
d) depends on h
CONCEPT - II
Dropping of an object :
If a person at rest drops an object its initial velocity will be zero and it starts accelerating downwards with
an acceleration a = g downwards.
If a person, moving with a velocity 'v' in the vertically upward direction, drops an object then its initia
velocity, u =v and acceleration a =-g(downwards).
inward direction, drops an object then its initial velocit
