This lesson describes the difference between potential and kinetic energy of a pendulum, and it explains how to calculate each.
As it accelerates down toward its lowest point (its midpoint, nearest the ground), this potential energy is converted into kinetic energy (energy of movement) and then, as the bob climbs up again, back to potential energy. So as the bob swings (oscillates) back and forth, it repeatedly ...
Potential Energy (PE) isstored energydue to position or state PE due to gravity = m g h Kinetic Energy (KE) is energy ofmotion KE = ½ m v2 The KE and PE are constantly calculated and you can see that their total stays the same (apart from slight changes due to rounding). ...

In pendulum motion,energyoscillates between kinetic energy andgravitational potential energy. At maximum height, gravitational potential energy is highest, while kinetic energy is zero. Conversely, at the lowest point, kinetic energy peaks and gravitational potential energy is zero. The height can be ca...

The conversation also touches on the equations for potential and kinetic energy and how they relate to finding the maximum speed and momentum of the pendulum. The conclusion is that the maximum kinetic energy corresponds to the maximum momentum, but to mathematically prove it, one needs to find ...
The gravitational potential energy of the pendulum is: where m is the mass of the rigid body, and Therefore, The kinetic energy of the pendulum is: where Ip is the moment of inertia of the pendulum about an axis passing through point P (this axis is perpendicular to the plane of motion...
In a pendulum system, when is it possible for the potential and kinetic energies both to be equal to zero? A pendulum with a length L and mass m starts at a time t = 0 with a velocity v = 0, displaced by an angle alpha. At the lowest point, it hits ano...
They are often used as simple harmonic oscillators in wave and vibration experiments. In addition, pendulums provide a simplified model for understanding concepts such as potential energy, kinetic energy, and conservation of energy. Pendulum Waves: Pendulum waves, also known as \...
