increases
decreases
remain same

if a body is falling freely the the acceleration due to gravity is taken as
equal
positive
negative
infinite
a free falling body under gravity will have uniform
speed
velocity
momentum
acceleration
the direction of acceleration due to gravity is always
towards the center of earth
along the tangent of earth
along the chord of earth
away from the surface of earth
two stones of different masses are dropped simultaneously from the top of a building . then which is correct among these (neglecting the air resistance)
larger stone hits the ground eariler
smaller stone hits the ground eariler
velocity of stones are independent of the mass
none
a body falls freely from height "h" after 2 seconds if acceleration due to gravity is reversed the body
continuously to fall down
falls down with retardation and goes up
falls down with uniform velocity
raises up with acceleration
if a body dropped freely from a height of 20m , then the velocity of the body as reaching to the ground is ( g=10m / s2)
100m / s
150m / s
