How would simple harmonic motion be different in the absence of friction?
If there is no friction to slow it down, then an object in simple motion will oscillate forever with equal displacement on either side of the equilibrium position. The equilibrium position is where the object would naturally rest in the absence of force.
What is true about the acceleration of a particle that is oscillating with simple harmonic motion SHM )?
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 does it hurt more if your hand is snapped with a ruler than with a loose spring even if the displacement of each system is equal?
Why would it hurt more if you snapped your hand with a ruler than with a loose spring, even if the displacement of each system is equal? The ruler is a stiffer system, which carries greater force for the same amount of displacement. The ruler snaps your hand with greater force, which hurts more.
When a spring of spring constant k is cut into two equal parts then spring constant of individual part becomes K What is the relation between K and K?
If the spring is cut into half and the same force F is applied to the half spring, the distance it should stretch is X/2, half of the original deformation. From this the new spring constant, K2 becomes K2= F/(X/2) or 2* (F/X) which is double of K.
How does spring constant depend on the material of the spring?
The spring constant will depend on the stiffness of the spring material, the thickness of the wire from which the spring is wound and, the diameter of the turns of the coil, the number of turns per unit length and the overall length of the spring.
Why simple harmonic motion is a periodic motion without energy loss?
Once the mass is displaced from its equilibrium position, it experiences a net restoring force. As a result, it accelerates and starts going back to the equilibrium position. As long as the system has no energy loss, the mass continues to oscillate. Thus simple harmonic motion is a type of periodic motion.
Does the acceleration of a simple harmonic oscillator remain constant during its motion?
Does the acceleration of a simple harmonic oscillator remain constant during its motion? Is the acceleration ever zero? No. Acceleration is maximum when the restoring force is maximum (when the oscillator is changing direction) at the maximum displacement from equilibrium (EQ).
What law governs both periodic motion and elastic potential energy?
Hooke’s Law and the phenomenon of simple harmonic motion help in understanding the physics associated with elastic objects.
