Oscillations in AP Physics C: Mechanics

If a spring obeys Hooke's law and has a spring constant $k$, what effect would halving $k$ and doubling the amplitude of oscillation have on the period of simple harmonic motion?

Which of these describes the motion of an ideal pendulum at its lowest point?

A pendulum bob swinging through its lowest point exhibits both translational and rotational motion; if it has linear speed $v$, mass $m$, radius $r$ from pivot point to center of mass, and moment of inertia $I$ about its center of mass, what is its total kinetic energy?

What term describes the product of force applied to an object and the time interval over which it is applied?

What is the acceleration of a mass attached to a spring in simple harmonic motion at its equilibrium position?

If the period of a mass-spring system is doubled, how does the spring constant k change?

For an object oscillating on a frictionless horizontal surface attached to an ideal spring with force constant $k$, which pair correctly relates linear analogs to their rotational counterparts?

What force is responsible for the periodic motion of a mass on a spring?

Which one of the following quantities is not a vector quantity in the context of mechanics?

A block attached to an ideal horizontal spring undergoes simple harmonic motion with initial energy $E$; if we replace this block with another one that has half its original kinetic energy but same potential energy when fully compressed or extended, how does this affect its frequency?
