Question
How is motion of a mass on a spring related to motion a) Displacement on a spring is like the tangent of the angle of circular motion with angular acceleration b) Displacement on a spring is like the area of motion is an ellipse c) Displacement on a spring is like the angular velocity of circular motion with constant angular acceleration d) Displacement on a spring is like the x coordinate of motion on a circle with constant angular velocity 5) Something rotates with a constant angular velocity. This means that the net torque on the object is: a) constant and not zero b) Constant and zero c) Increasing over time d) Decreasing over time What measures how difficult it is to change the rotation of an object? a) Mass b) Torque c) Angular momentum d) Moment of inertiaExplanation / Answer
(5) ans
the correct option is B
because the torque =I*dw/dt
here the angular velocity is constant if the the time changes the angular velocity is not change
so the angular acceleration is zero torque is zero
(6) ans
the correct option is B
because the motion of the object is measure to change is torque
