Negative acceleration is also known as
Retardation
Uniform Acceleration
Change in acceleration
None of these
The velocity of a car at 10.50 a.m is 60 km/hr and at 10.52 a.m. it is 80 km/hr. Assuming constant acceleration in the given period its value is
600 km/hr2
500 km/hr2
400 km/hr2
300 km/hr2

The force of gravity acting on a body is called
Mass of the body
Weight of the body
Inertia of the body
Momentum of the body
Kinetic energy is directly proportional to
Square of the velocity
Cube of the velocity
Half of the velocity
velocity
What type of motion is the motion of tip of second's hand of a watch?
Uniform motion
Accelerated motion
Non uniform motion
A particle is travelling with a constant speed. This means that
its position remains constant as time passes
it covers equal distances in equal time intervals
its acceleration is zero
it does not change its direction of motion
For motion on a straight line path with constant acceleration,the ratio of magnitude of displacement and the distance covered is
= 1
> 1
< 1
≤ 1
A body has a uniform motion when
it covers equal distances in unequal intervals of time
it covers unequal distances in equal intervals of time
it covers equal distances in equal intervals of time
Velocity is a
Scalar quantity
Vector Quantity
