Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position. The acceleration of a particle executing simple harmonic motion is given by, a(t) = -ω2 x(t).
Why is acceleration zero at equilibrium in SHM?
As the mass moves toward the equilibrium position, the displacement decreases, so the restoring force decreases and the acceleration decreases. When the mass reaches the equilibrium position, there is no restoring force. The acceleration, therefore, is zero, but the mass is moving at its highest velocity.
What is true about the acceleration of a particle that is oscillating with simple harmonic motion?
Which one of the following statements about the acceleration of the oscillating particle is true? It is least when the speed is greatest. It is always in the opposite direction to its velocity. It is proportional to the frequency….Simple Harmonic Motion – Multiple Choice Questions.

Why is acceleration greatest in simple harmonic motion?
Because the force is proportional to the displacement from the equilibrium position F=−kx, the further you from the equilibrium position the stronger the force and since the mass that’s undergoing SHM isn’t changing as well as friction being absent, the force is greatest so acceleration is highest.
Where the acceleration of a particle in simple harmonic motion is maximum?
equilibrium position
At the equilibrium position, the velocity is at its maximum and the acceleration (a) has fallen to zero. Simple harmonic motion is characterized by this changing acceleration that always is directed toward the equilibrium position and is proportional to the displacement from the equilibrium position.
What is the acceleration of simple harmonic motion?
For simple harmonic motion, the acceleration a = -ω 2 x is proportional to the displacement, but in the opposite direction. Simple harmonic motion is accelerated motion. If an object exhibits simple harmonic motion, a force must be acting on the object.
Why acceleration is always negative in physics?
So the value of acceleration is always negative. Acceleration becomes negative when a particle is moving to some direction but slowing down because its acceleration vector is pointing in the opposite direction of the displacement.
Why is there a minus sign in simple harmonic motion?
Re: Simple Harmonic Motion. acceleration and displacement are vectors. they have direction. the acceleration is opposite in direction to the displacement and tries to bring it back. hence the minus sign to signify that the two vectors are opposite in direction.
What does the negative sign indicate in acceleration and displacement?
The negative sign indicated that acceleration and displacement are in opposite direction of each other. Equation I is the expression of acceleration of S.H.M. Practically, the motion of a particle performing S.H.M. is accelerated because its velocity keeps changing either by a constant number or varied number.
