The quantities having both magnitude and direction
scalar quantity
vector quantity
constants
variable quantity
Rate of change of distance is called
velocity
speed
displacement
acceleration
the quantity of motion contained in an object is called
distance
displacement
force
momentum
The SI unit of momentum
m/s
kgm/s
m
none
An object moves with constant speed of 5 m/s along the circumference of a circle .Then
acceleration is zero
acceleration is positive
velocity is zero
None
If an object covers equal distance in equal intervals of time .then its motion is said to be
uniform
nonuniform
accelerated
decelerated
unit of retardation is
m/s
m/s2
m
none
The slope displacement-time graph gives
speed
velocity
acceleration
distance
Area under velocity -time graph gives
speed
acceleration
distance
displacement
The inability of an object to change its state is called
momentum
acceleration
inertia
friction
when mass increases
inertia increases
inertia decreases
momentum increases
both A and C
rate of change of momentum gives
acceleration
force
speed
velocity
An object travelling with speed of 5m/s stops suddenly.the acceleration produced is
zero
positive
negative
None
complete the equation,V2 =
2aS+U2
2aS-U2
ut+1/2 at2
-2aS+U2
In a bus starts passengers falls backward ,
due to inertia of rest
due to inertia of motion
due to inertia of direction
due to lack of friction
if the net force acting on a body is zero
the forces are balanced
the forces are unbalanced
force will produce motion
force will not produce motion
both A and D
The first law states
the quality of force which can produce motion
the quantity of force which can produce motion
the law of inertia
both A and C
while catching the ball cricketer moves his hands backward for reducing
rate of change of momentum
force
reducing pain on hand
all the above
the law of inertia was introduced by
Galileo
Newton
Einstein
Aristotle
momentum is a
scalar quantity
vector quantity
Can be a scalar or vector
None
