A particle of mass m oscillates along x-axis according to equation x =...
(ωt + φ), where a is the amplitude, ω is the angular frequency, t is time, and φ is the phase angle. The displacement of the particle from its equilibrium position at any time t is given by x(t) = a sin(ωt + φ).
The velocity of the particle at any time t is the derivative of the displacement with respect to time, which is given by:
v(t) = aω cos(ωt + φ)
The acceleration of the particle at any time t is the second derivative of the displacement with respect to time, which is given by:
a(t) = -aω^2 sin(ωt + φ)
The negative sign indicates that the acceleration is in the opposite direction to the displacement. This means that when the particle is at its maximum displacement, the acceleration is zero, and when the particle passes through the equilibrium position, the acceleration is maximum.
The period of the motion is the time taken by the particle to complete one full oscillation. It is given by:
T = 2π/ω
The frequency of the motion is the number of oscillations per unit time. It is given by:
f = ω/2π
The maximum velocity of the particle is given by:
v_max = aω
The maximum acceleration of the particle is given by:
a_max = aω^2
The energy of the particle is the sum of its kinetic and potential energies. At any time t, the total energy of the particle is given by:
E(t) = (1/2)mv^2 + (1/2)kx^2
where k is the spring constant. The energy is constant throughout the motion, and is equal to the total energy at any other time.
