At the bottom of it's motion because the gravitational potential energy is zero
On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing. On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.
Frictionlist pendulum is an example of the pendulum of a clock, a reversible process, free.
Earth's rotation affects a pendulum due to the Coriolis force, which causes the pendulum's plane of oscillation to rotate clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere. This rotation is a result of the pendulum's inertia attempting to maintain its orientation as Earth rotates underneath it. The Coriolis effect causes the apparent deflection of the pendulum's swing.
According to the mathematics and physics of the simple pendulum hung on a massless string, neither the mass of the bob nor the angular displacement at the limits of its swing has any influence on the pendulum's period.
Is law catalyst for starting the pendulum swinging? or is ethics? politics?
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).
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.
A pendulum moves at its fastest when it is at the bottom of its swing, also known as the equilibrium position. At this point, all the potential energy has been converted to kinetic energy, resulting in the highest speed of the pendulum.
At the bottom of it's swing. This is because it has accelerated to it's peak velocity due to gravity.
The kinetic energy is greater at the bottom of the swing because the pendulum is moving fastest at that point. As the pendulum swings down, the potential energy is converted into kinetic energy, resulting in increased speed at the bottom.
At the bottom of its swing in the center, the pendulum has maximum kinetic energy (KE) and no potential energy (PE) because it is moving its fastest and is at its lowest point.
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
At this point, at the top of the swing, the pendulum has potential energy. As it drops it loses potential and gains kinetic energy. At the fastest point, as the pendulum reached the bottom of the swing, it has kinetic energy. It then loses kinetic energy and gains potential energy as it swings up to the other side.
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.
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
The weight on a pendulum is a 'mass' or a 'bob'.
On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing. On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.
