Simple Harmonic Motion Conceptual Questions.

When an object oscillates back and forth on the end of a spring what occurs at some time during the course of motion?

The object will experience zero acceleration and simultaneously nonzero velocity. Since its at equilibrium .

An object of mass oscillates on the end of a spring to double its period what must you do?

Multiply the mass by four since the mass is under a square root.

How do you increase the oscillation frequency of a mass on a horizontal spring with the constant of k?

Decreasing the mass will cause a increase in frequency.

How does the angle of a pendulum affect it's period?

It doesn't the only factor affecting the period would be the length of the pendulum.

How does the mass of a pendulum affect it's period?

It doesn't the only factor affecting the period would be the length of the pendulum.

How do you speed up or slow down a pendulum?

You increase the length to slow it down however you shorten the length to increase it's speed.

Two equal masses are attached to a separate identical springs, one mass is pulled to 40cm and the other only 20cm. The masses are released simultaneously what mass reaches equilibrium first?

Both will reach it at the same time since there the same mass and displacement doesn't affect the period of a spring.

For a SMH oscillator when if ever are the displacement and velocity the same?

When moving towards the equilibrium

For a SMH oscillator when if ever are the displacement and acceleration vectors in the same direction?

They are never the same.

How could you estimate the height/length of a pendulum?

Use the period equation to find it.

A block is attached to the lower end of a vertical spring oscillating up and down. If the spring obeys Hooke's Law, the period of oscillation depends on what?

The mass of the block and force constant of the spring.
