Potential energy, stored energy that depends upon the relative position of various parts of a system. For example, a steel ball has more potential energy raised above the ground than it has after falling to Earth. Learn more about potential energy in thi

PendulumFor a good example of PE and KE have a play with a pendulum.Gravitational Potential EnergyWhen the PE is due to an objects height then:PE due to gravity = m g hWhere:m is the objects mass (kg) g is the "gravitational field strength" of 9.8 m/s2 near the Earth's surface ...
Homework Statement What % of PEg must be converted in KE in order to double the speed of a pendulum? So I have spent a couple of days trying to figure out this problem (it's a lab), and I can't seem to figure it out. I have asked my physics teacher about it, and he said th...
In a system and method for converting potential energy into electrical energy, a force is applied to a force receiving end of a pendulum arm of a pendulum. The pendulum arm is connected to a periphery of a wheel. The wheel is rotated using the force applied through the pendulum arm and ...
In a pendulum system, when is it possible for the potential and kinetic energies both to be equal to zero? How are velocity and momentum related? Find the total energy and kinetic energy (in GeV) and the momentum (in GeV/c) of a proton whose speed is 0.900c. The mass of the proton...
Consider the case of a simple pendulum of a massive bob hanging at the end of a massless rod that is pivoted at a fixed point. If the pendulum is given a velocity from its equilibrium position, it executes a simple harmonic motion where energy is conserved at all points. As the bob is...
