only rotational acceleration can produced a change in rotational velocity.
Force can be acted along rotation axis and toward rotational axis which cannot produce a rotational torque.
A change in the rotational velocity of an object is produced by a non zero O...
in circlar motion, a non zero tangential acceleration change only the magnitude of the velocity, but not its direction. true false need more information none of the above
For a certain interval of time, an object is acted on by a constant non zero force. Which of the following statements is true for this interval of time? The objects' velocity changes. The object is moving with constant velocity The object is accelerating. The object is at rest. The object's velocity can only increase.
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...
For a certain interval of time, an object is acted on by a constant non-zero force. Which of the following statements is true for this interval of time? (Select all that apply.) The object's velocity changes. The object is moving with constant velocity. The object's velocity can only increase. The object is at rest. The object is accelerating.
is it possible for an object to have zero velocity but non-zero acceleration? If so, give an example from your experiments. In any case, explain why. A motion diagram might help.
please find the accelaration, translational kinematics, and rotational kinematic energy. time= 2 seconds inital velocity=0 final velocity= 0.115 m/s angular velocity= pi/8 rad/s mass= 2.29 grams angle of displacement= 45 degress displacement= 23 cm or 0.23 meters
2.) Which of the following quantities will impact how a rigid body's rotational speed can change? a.) the body's rotational inertia b.)the net torque on the body c.) the net force on body d) a and b e.) b and c f.) all of above
Is it possible to have a non-zero net force on an object that does no work on the object? if not, explain why. if so, provide an example.
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
7. A non-conservative force does 300 of work on an obiect while the object is rolling uphill. During the application of the force the gravitational potential energy of the object increases by 4001 while the rotational kinetic energy decreases by 2001, what is the change in the translational kinetic energy of the object?
