An object attached to an ideal spring executes simple harmonic motion. If you want to double its total energy, you could

• double the amplitude of vibration
• double the force constant (spring constant) of the spring
• double both the amplitude and force constant (spring constant).
• double the mass

An object is attached to a vertical spring and bobs up and down between points A and B.  Where is the object located when its kinetic energy is a maximum?

• at either A or B
• midway between A and B
• one-third of the way between A and B
• one-fourth of the way between A and B
