When it is exactly at its lowest point; the point where it is closest to the ground. Before that point it is accelerating; after that point it is decelerating.
At the bottom of it's swing. This is because it has accelerated to it's peak velocity due to gravity.
Potential energy is the greatest at the top of the pendulum swing, precisely as it is stopped. Kinetic energy is greatest at the bottom of its swing as it is moving its fastest. Between the two points the energies are converting into one another.
-- friction in the pivot -- air moving past the pendulum -- the effective length of the pendulum -- the local acceleration of gravity
This could be quantified using calculus, but to simply know WHERE it is fastest but not how fast, simple first principals are all that is required - that of conservation of energy. At the low point the pendulum has it's least Potential Energy (PE) - it has fallen as far as it can. As it rises it gains PE, gathering that energy by reducing the Kinetic Energy (energy of motion) of the mass. Clearly the pendulum is traveling fastest at the bottom.
making timings by sighting the bob past a fixed reference point (called a 'fiducial point')Sighting the bob as it moves fastest past a reference point. The pendulum swings fastest at its lowest point and slowest at the top of each swing.· The bob of the pendulum was displaced with a small angle· The amplitude of the oscillation of a simple pendulum is small.· The simple pendulum oscillates in a vertical plane only.· Switch off the fan to reduce the air resistance
A swinging pendulum is moving fastest at the lowest point of its arc. That is the point where all its potential energy has been converted into kinetic energy, and it is the only point in a pendulum's arc where that happens. See related link (a simulation).
At the bottom of it's swing. This is because it has accelerated to it's peak velocity due to gravity.
The rotation of the earth keeps a foucault pendulum moving
Potential energy is the greatest at the top of the pendulum swing, precisely as it is stopped. Kinetic energy is greatest at the bottom of its swing as it is moving its fastest. Between the two points the energies are converting into one another.
a cold front is the fastest moving front

The eyelid is the fastest moving eyelid in the human body
Yes. You can increase the period by moving the pendulum to a location where the gravitational force is weaker.Alternatively, you can increase the effective length of the pendulum. The pendulum may be of fixed length, but you can still increase its effective length by adding mass to any point below its centre of gravity.Yes.
