Question

Q. If the angular velocity of rotation of
an object is doubled, with the radius of
the circular path remaining the same
find the percentage change in centripetal
acceleration.​

Answer 1

Answer:

Frequency is constant, thus its angular velocity is constant w=2πf

Initial centripetal force F=mr

1

w

1

2

But radius is doubled r

2

=2r

1

∴ New centripetal force F

2

=mr

2

w

2

=m(2r

1

)w

2

=2F
