As we can see in the following image, where it is shown how the projection on a diameter of the position of a particle that describes a circular motion obeys the equation of the x position. From P draw PN perpendicular to YY ’ . Which one of the following statements is true when an object performs simple harmonic motion about a central point O? (c) The acceleration and the displacement from O are always in the same direction. where k is a constant. Periodic motion in which a system returns to its initial position at a later time. Stiff springs have a large value of k, Many people like to write, they make a living from…. point in a sinusoidal manner as a function of time. The notes contain an overview and questions of the chapter. (b) When the particle is at the extreme position (i.e) y = +a, acceleration is ∓ a ω2 which is called as acceleration amplitude. Note: Equilibrium point is the point where net force and/or net torque is zero.

One of our academic counsellors will contact you within 1 working day. turn to the special case of simple harmonic motion. Computer Science Graduate from IIT Bombay. When the displacement is maximum, however, the velocity is zero; when the displacement is zero, the velocity is maximum. With the blend of education & technology, eSaral team made the learning personalized & adaptive for everyone. Right. If m is the mass of the particle, restoring force that tends to bring back the particle to the mean position is given by.

Of all the different types of oscillating systems, the simplest, mathematically speaking, is that of harmonic oscillations. This revision series is free for all. (b) v2/a (sin θ) in a direction parallel to YO. The rate of change of displacement is the velocity of the vibrating particle.

Furthermore, the interval of time for each complete vibration is constant and does not depend on the size of the maximum displacement. called Hooke's Law. • Difference between oscillation & vibration: When the frequency is small, we call it oscillation. The k in the equation is called the spring constant; Then amplitude of oscillation is, Or, A = v√(m/k) = 6√(0.1/10) = 6/10 = 0.6 m. Thus from the above observation, we conclude that, option (a) is correct. We know that, linear velocity = radius × angular velocity, Velocity =  aω √1- (y/a)2       (Since, sin θ = y/a). (a) When the particle is at mean position, (i.e), (b) When the particle is in the extreme position, (i.e), (a) When the particle is at the mean position (i.e), (b) When the particle is at the extreme position (i.e), It will be clear from the above, that at the mean position, = 0, velocity of the particle is maximum but acceleration is zero. Let's take this relationship to a higher mathematical level, The examples of periodic motion are the motion of planets around the Sun, motion of hands of a clock, motion of the balance wheel of a watch, motion of Halley’s comet around the Sun observable on the Earth once in 76 years.
