True/False Physics Exam 3
An object completely submerged in water must either rise or fall.
False
An object in motion with constant speed along a straight line can never have nonzero angular momentum
False
If an object is in unstable equilibrium, any small displacement results in a restoring force or torque, which tends to return the object to its original equilibrium position
False
When a rigid body rotates about a fixed axis all the points in the body have the same linear displacement
False
When a rigid body rotates about a fixed axis all the points in the body have the same tangential speed
False
When a rigid body rotates about a fixed axis all the points in the body have the same centripetal acceleration
Fasle
If an external pressure is applied to a confined fluid, the pressure at every point within the fluid increases by that amount
True
Unbalanced torques produce rotational accelerations, and balanced torques produce rotational equilibrium
True
When a rigid body rotates about a fixed axis all the points in the body have the same angular displacement
True
When a rigid body rotates about a fixed axis all the points in the body have the same angular speed
True
