8
) acceleration can be a function of
displacement a(x) ,
A ) True
,

9
) For the curvilinear motion of a
particle, is it always necessary to move along a circular path .
A ) Yes
,
B
) No ,
Correct
answers : - B ) No ,
10
) Sometimes we use the term deceleration
to refer the rate of decrease in speed .
A
) True ,
B
) False ,
Correct
answers: A ) True ,
11
) Velocity and acceleration can be in
the same or different directions .
A
) True ,
B ) False ,
Correct
answers: A ) True ,
12
) When a and v are in the same direction
, the particle speeds up ,
A
) True ,
B
) False ,
Correct
answers : - A ) True ,
13

directions, the particle slows down .
A
) True ,
B
) False ,
Correct
answers : - A ) True
,
14
