6. A constant net torque is applied to a rotating object. Which of the following best describes the object's motion A) The object will rotate with increasing angular acceleration. B) The object will rotate with decr C) The object will have a decreasing moment of inertia D) The objeet will rotate with constant angular velocity E) The object will rotate with constant angular acceleration. easing angular acceleration.
When a net torque is applied to a rigid object it always produces a 1. constant acceleration 2. rotational equilibrium 3. constant angular velocity 4. constant angular momentum 5. change in angular velocity
orrect Question 1 0/2p When a net torque (non-zero) is applied to a rigid object, it always produces change in angular velocity constant angular velocity constant linear acceleration rotational equilibrium constant angular momentum correct Question 2 0/2 pts You are struggling to get a rusty bolt loose with a wrench. If you are maxed out on the force you can apply, what could you do/change to increase rotational motion of the bolt? Move your hand away from the bolt Move...
If the net torque on a rotating object is zero, the angular velocity of the object cannot change. True or False? Explain A. True , Explan: _________ B False , Explan: _________ (I know the answer is B, I need help on explanation) Thanks
If an object is in static equilibrium, there must be no net external torque: A) Group of answer choices about an axis located at the edge of the object. B)about an axis located at the object's center of gravity. C)about an axis located beneath the object's center of gravity. D) about any axis.

An object that is in static equilibrium has which of the following properties? (Select all that apply.) Moves at a constant speed. Has no velocity. Cannot have any form of mechanical energy. Has no net torque acting. Has no net force acting. Has no angular velocity.
A grinding wheel is initially at rest. A constant external torque of 50N*n is applied to the wheel for 20 s, giving the wheel an angular speed of 600 rev/min. The external torque is then removed, and the wheel comes to rest 120 s later. a) Find the amount of inertia of the wheel b)Find the frictional torque, which is assumed to be constant
