Simple Harmonic Motion Flashcards
1
Q
What is the formula for the time period of a mass-spring system?
A
T = 2 pi sqrt(m/k)
2
Q
What is the formula for the time period of a pendulum system?
A
T = 2 pi sqrt(l/g)
3
Q
What is the spring constant for springs in series?
A
1/k = 1/k1 + 1/k2
4
Q
What is the spring constant for springs in parallel?
A
k = k1 + k2
5
Q
What is critical damping?
A
Where the damping force reduces the amplitude of oscillation as fast as possible, does not complete one full oscillation
6
Q
At what amplitudes is SHM a good approximation for a pendulum?
A
Less that 10 degrees
7
Q
How do you find the total energy of a pendulum system?
A
Find the maximum kinetic energy
