how are mass and period of a spring related?
directly
200
for an oscillating mass spring system, at what position is the max, force and acceleration experienced?
at the amplitude
200
What is the period of a 2 kg mass oscillating on the end of a spring (k = 100 N/m).
0.89 s
200
What is the period of a pendulum that is 1 m long?
2 s
300
Where is the Sun located relative to Earth's orbit?
a foci
300
If you double the period, what happens (specifically) to the frequency?
1/2x
300
At what position is the velocity and kinetic energy at a max for an oscillating pendulum?
through equilibrium
300
What is the mass that oscillates at the end of a 150 N/m spring with a period of 2 seconds.
15 kg
300
What is the frequency of a pendulum that is 1 m long?
0.5 Hz
400
True or false:
The period of a planet’s revolution around the Sun (the length of a planet's year) is inversely proportional to its distance from the Sun
False
400
If you increase the length of a pendulum, what happens to the frequency of the pendulum
decreases
400
The period of a pendulum undergoing SHM is completely independent of which of the following:
-length of pendulum
-mass of bob
-angle of release
-acceleration due to gravity
mass and angle of release (assuming small angle approximation holds)
400
If you double the displacement of spring, how much more energy would the mass spring system possess?
4x
400
A pendulum is oscillating in SHM with a frequency of 0.5 Hz. The mass of the bob is 2 kg. What is the length of the pendulum, and what would its frequency be if the mass of the bob doubled?
0.99 m
It would be the same, the mass of the bob does not affect the frequency of a pendulum.
