which of the following quantities may remain constant during the motion of an object along a curved path
velocity
speed
acceleration
magnitude of acceleration

anchitsaini

speed
acceleration
magnitude of acceleration

the above 3 seem to be the answers

amitp91

but have another question
is the acceleration of a particle in uniform circular motion constant or variable

anchitsaini

but is my answer correct??

amitp91

ya ur first answer is correct
answer the secnd one

anshulpatel

magnitude of acceleration

and

speed ...............

during uniform circular motion magnitude of acceleration remaims constant

morningdew

magnitude is constant, direction varies
It always points towards the centre

amitp91

i have asked is the acc. of a particle in uniform motion constant or variable

morningdew

this was the ans to the second ques
the ans to the first ques is the same as anchit

morningdew

acc varies

amitp91

then in the first question u have told that the acc. is constant
then how it varies in the second one

anchitsaini

accn varies

amitp91

all of u watch these two questions

1)which of the following quantities remain constant during the motion of an object along a curved path
1) velocity 2)SPEED
3) ACCELERATION 4) MAGNITUDE OF ACC
ANSWER: 2,3,4

2 Q . IS THE ACC. OF A PARTICLE IN UNIFORM CIRCULAR MOTION CONSTANT OR VARIABLE
ANSWER : VARIABLE

HOW TWO DIFFERENT ANSWERS FOR ACCELERATION . ONCE THE ACC. IS CONSTANT AND THEN IT IS VARIABLE
