The ideal model of a simple pendulum assumes the pendulum mass is concentrated at a single point, the string or rod is massless and frictionless, and the pendulum moves in a vacuum with no air resistance. Additionally, it assumes small amplitude oscillations, and the only force acting on the pendulum is gravity.

Why a compound pendulum is called equivalent simple pendulum?
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
Differences between compound pendulum and simple pendulum?
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
Could we ever construct a true simple pendulum?
Yes, a simple pendulum consists of a mass (bob) attached to a string fixed at a pivot point - this can be easily constructed using everyday materials. By ensuring the string length is much longer than the amplitude of the swing and minimizing air resistance, the pendulum's motion can closely approximate that of an ideal theoretical simple pendulum.
Can you realize an ideal pendulum?
An ideal pendulum refers to a theoretical concept with no energy loss – a mass swinging indefinitely without slowing down. In reality, factors like air resistance and friction make this impossible. By minimizing these influences in a vacuum and using precise materials, we can create a more accurate representation of an ideal pendulum, although true perfection remains unattainable.
Why does a ideal pendulum swing back and forth indefinitely?
An ideal pendulum swings back and forth indefinitely due to the conservation of mechanical energy. Potential energy is converted to kinetic energy as the pendulum swings, and vice versa. In the absence of friction and air resistance, this energy exchange allows the pendulum to continue swinging without losing amplitude.
