Why does a pendulum lose energy?

The pendulum loses energy to wind resistance, friction between the tube and the string, and internal friction within the bending string. Then the driver allows the force of gravity to convert some of that extra energy to kinetic energy, by allowing the bob to fall an extra distance at large angles. Keeping this in consideration, what law does a pendulum follow? Physicists use Newton's first, second and third laws to prove the horizontal string tension moves the pendulum without regard to mass or gravity. The laws of a simple pendulum follow the ideas of Newton's three laws of motion.

Do pendulum clocks need batteries?

Little did I know back then, but pendulum clocks don't need batteries at all! It may seem like it's just idling around, serving no real purpose as it swings to and fro, but that action is actually what keeps the clock accurate to the second. One may also ask are pendulums infinite? pendulum is infinite.. Actually the pendulum's time period is : T=2??l/g applicable when the angle made by the string from the mean position is small.. that is we consider it to be SHM.

In respect to this, why do shorter pendulums swing faster?

where l is the length of string of the pendulum and g is the acceleration due to gravity. So, when l is shorter, the time period of the pendulum decreases which means it has higher frequency which implies that it swings faster. Will a pendulum swing forever in a vacuum? If you manage to eliminate all these effects then yes, the pendulum will oscillate forever.

What is torsion pendulum?

A torsional pendulum is an oscillator for which the restoring force is torsion. For example, suspending a bar from a thin wire and winding it by an angle , a torsional torque. (1) is produced, where is a characteristic property of the wire, known as the torsional constant.
