Simple Harmonic Motion Flashcards
1
Q
Definition of SHM
A
Displacement is proportional to and in the opposite direction of acceleration.
2
Q
Damping of an SHM system
A
Describes the rate at which energy is lost from an SHM system.
3
Q
Critically damped system
A
One that ensures an oscillator comes to rest in the minimum time possible.
4
Q
Example of a damped SHM system
A
One that exists in a viscous fluid.
5
Q
Is acceleration constant in an SHM system
A
No it varies
6
Q
Hookes Law Equation
A
F=-ky
F is force in Newton’s produced by an extension of y metres.
k is spring constant in Nm^-1
7
Q
Tension in spring equation
A
T=-ky
T is tension in N
8
Q
Acceleration is proportional to
A
-y (displacement) a=-w^2y
9
Q
Proportionality comes from
A
w^2
10
