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
