Motion in a straight line is called
circular motion
periodic motion
rectilinear motion
translatory motion
Velocity is a
Scalar quantity
Vector quantity
Both scalar and vector
Cannot be predicted
Kinetic energy is directly proportional to
Square of the velocity
Cube of the velocity
Half of the velocity
velocity
The position of a particle going along a straight line is x1 = 50 m at 10.30a.m. and x2 = 55 m at 10.35 a.m.The displacement between 10.30 a.m and 10.35 a.m. is :
2 m
5 m
7 m
9 m
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
m / s2 is the unit of :
speed
acceleration
displacement
time
Acceleration is defined as the rate of change of
distance
Velocity
None of these
Vector Quantity
Both Scalar and Vector

Uniform motion
Accelerated motion
Non uniform motion
Unit of Angle is
Candela
Weber
Radian
Lux
