What is the equation for the period of a spring?
2pi square root(m/K)
100
How much effect does changing the mass have on a pendulum?
None
100

When is the restoring force strongest?

At the extreme positions (x = ±A), because the restoring force is proportional to the displacement from equilibrium.

Where is energy mainly kinetic?

At the equilibrium position, where the velocity is maximum and the elastic potential energy is minimum.

200

Does the period depend on the amplitude in ideal SHM?

No, the period is independent of the amplitude.

Find Vmax if the period is 1.99 and the amplitude is 5
15.79 m/s
300

What is the direction of acceleration when the mass is to the right of equilibrium?

The acceleration points to the left, toward the equilibrium position.

300
What is the type of graph used for SHM?
Sinusoidal
300

Is simple harmonic motion periodic?

Yes, it repeats itself at regular time intervals.

400

In a pendulum ideal system, how is that Kinetic energy variates trough the displacement of the pendulum?

Decreases everytime the maximum/minimum displacement is reached


400
How do you find angular velocity?
v/r
400
Which law is associated with SHM?
Hooke's law
400

Which type of energy is maximum when the system is momentarily at rest?

Potential energy.

500

Acceleration behaviour at equilibrium 

Its zero

500

Where does the acceleration have its maximum magnitude?

At the extreme positions (x = ±A), where the displacement from equilibrium is largest.

500
What constitutes a period on the SHM track?
a return to the same point

At which positions does the system change direction?

At extreme positions
