Simple harmonic motion equation form

Click For Summary
SUMMARY

The equation of motion for simple harmonic motion (SHM) of a mass on a spring is defined as y = A cos(ωt), where A represents the amplitude and ω is the angular frequency. For the scenarios presented: (a) when released 10 cm above the equilibrium position, the equation is y = 0.10 cos(t/√(m/k)); (b) for an upward push resulting in an 8 cm maximum displacement, the amplitude A is 0.08; (c) for a downward push with a 12 cm maximum displacement, the amplitude A is 0.12. The angular frequency ω can be expressed as 2π/T, where T is the period of oscillation.

PREREQUISITES
  • Understanding of simple harmonic motion (SHM) principles
  • Familiarity with spring constants (k) and mass (m)
  • Knowledge of angular frequency (ω) and period (T)
  • Ability to manipulate trigonometric functions in equations
NEXT STEPS
  • Study the derivation of the SHM equation y = A cos(ωt)
  • Explore the relationship between mass, spring constant, and angular frequency
  • Learn how to calculate the period of oscillation for different spring systems
  • Investigate the effects of varying initial conditions on SHM behavior
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and oscillatory motion, as well as educators seeking to explain the principles of simple harmonic motion.

Homework Statement


what is the form of the equation of motion for the SHM of a mass suspended on a spring when the mass is initially (a)released 10 cm above the equilibrium position; (b) given an upward push from the equilibrium position, so that it undergoes a maximum displacement of 8cm; (c) given a downward push from the equilibrium position, so that it undergoes a maximum displacement of 12 cm?


Homework Equations



So I know y= Acos(t*2*pi)/T

The Attempt at a Solution


so would (a) just be y = .10cos t/[square root(m/k)]

That looks right to me; you can change the square root and move it around if you like, though (to get it out of the denominator), but since they don't tell you anything about the spring I'm guessing they don't care about how you write the argument of the cosine function.
