According to the relationship between torque and angular acceleration, what happens when you have more torque (given a constant rotational inertia)?
a. the angular acceleration increases.
b. the angular acceleration decreases.
c. the angular acceleration stays constant.
d. not enough information to know.

The angular acceleration increases.

Explanation:

The relationship between the torque and angular acceleration is :

Where

I is the moment of inertia

is the angular acceleration

We can see that the torque is directly proportional to the angular acceleration. So, when we have more torque it means angular acceleration increases. Hence, the correct option is (A).
