When a pendulum swings the size of the swing gradually reduces with time until the pendulum stops explain how this can be possible if energy is conserved?
Energy is conserved in an isolated system, meaning since energy cannot be created or destroyed, the amount of energy in the system is the same.
The point is, what is the 'system' in a certain scenario. Even if the pendulum was in an isolated room, that doesn't mean the pendulum will swing forever, because energy is constsntly lost to the environment, due to the friction with the air. But while energy is lost from the pendulum, energy is gained by the surrounding air molecules (also isolated), and thus energy in the system is conserved.
Eventually the pendulum's kinetic energy will be zero, having lost too much to be able to make it move.
What else can I help you with?
Is the potential energy of the pendulum changing at position E explain?
At position E, the potential energy of the pendulum is at its maximum. As the pendulum swings, the potential energy is converted into kinetic energy, reaching a minimum at the lowest point of the swing. The potential energy is constantly changing as the pendulum moves due to the force of gravity acting on it.
Is mechanical energy always conserved Can you explain why or why not?
Mechanical energy is not always conserved. It can be converted into other forms of energy, such as heat or sound, through processes like friction or collisions. This means that the total amount of mechanical energy in a system may change over time, making it not always conserved.
Which letters represent the positions of maximum potential energy of the pendulum explain?
The positions of maximum potential energy in a pendulum are at the highest points of its swing, where the pendulum momentarily stops before changing direction. This corresponds to the top-most points of the swing, which are generally labeled as positions A and C in diagrams.
Explain how energy is conserved in the simple pendulum?
In a simple pendulum, the total mechanical energy (potential energy + kinetic energy) remains constant if we ignore external factors like air resistance. As the pendulum swings back and forth, the potential energy is converted to kinetic energy and vice versa, but the total energy remains the same due to the conservation of energy principle.
Is linear momentum conserved in common applications Explain?
Yes, linear momentum is conserved in common applications such as collisions, explosions, and interactions between objects. This principle states that the total linear momentum of a system remains constant before and after the event, assuming no external forces are acting on the system.

How do you explain why there is no natural numbers?
It is not possible to explain a false proposition.
What will happens to the time period of simple pendulum if bob of the pendulum is completely immersed in water Explain?
Essentially , a simple pendulum is ignorant of air resistance, its more a tool to calculate gravitational acceleration, immersing it in liquid would introduce a drag force and bouyancy on the bob which alters the net force on the bob (essentially reducing the gravity)

Explain how the length of a string affects the motion of a simple pendulum?
You mean the length? We can derive an expression for the period of oscillation as T = 2pi ./(l/g) Here l is the length of the pendulum. So as length is increased by 4 times then the period would increase by 2 times.
