None of these
Explanation
In
rotational motion
,
torque
is the rotational analog of
force
in linear motion.
Just as force causes
linear acceleration
(Newton's Second Law:
F = ma
).
Torque causes
angular acceleration
(
τ = Iα
), where
τ
is torque,
I
is the moment of inertia, and
α
is angular acceleration.
