The pendulum clock The first pendulum clock In the Dutch scientist Christiaan Huygens built the first pendulum clock. Eventually, the first pendulum has no more energy to give to the second pendulum. It was found that a major source of error was that the pendulum rod expanded and contracted with changes in ambient temperature, changing the period of swing.
And then back again. Start the pendulum swinging again. Tape the back of your phone to the other end of the string. Measuring the restoring force Measure the restoring force for a simple pendulum. You might also notice that the tension force is slightly larger than this component of gravity.
The wood had to be varnished to prevent water vapor from getting in, because changes in humidity also affected the length. Sean Carroll relates the story of Galileo's discovery of the fact that for small amplitudes, the period and frequency are unaffected by the amplitude.
You will notice that this vector is entirely tangent to the arc when at maximum displacement; this is consistent with the force analysis discussed above. When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position.
This expression for period is reasonably accurate for angles of a few degrees, but the treatment of the large amplitude pendulum is much more complex. In physical situations in which the forces acting on an object are not in the same, opposite or perpendicular directions, it is customary to resolve one or more of the forces into components.
Repeat steps 1—9 for your other pendulum lengths. If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help.
Their work serves to develop the next generation of scientists and engineers, including all healthcare professionals. This occurs because the pendulum moves back and forth first in one direction, then the other for one complete period; giving two peaks in the Y acceleration graph per swing of the pendulum's motion.
Huygens' Horologium Oscillatorium In17 years after he invented the pendulum clock, Christiaan Huygens published his theory of the pendulum, Horologium Oscillatorium sive de motu pendulorum. You can see this working if you look at the wave: This experiment shows energy being transferred back and forth between the pendulums.The motion would be oscillatory, but not simple harmonic motion, because simple harmonic motion implies sinusoidal behavior, where the second derivative of the displacement is proportional to the displacement as you pointed out.
– tmwilson26 Oct 14 '15 at Nov 09, · This cool physics demo illustrates the simple harmonic motion of a pendulum while teaching kids the important concepts of potential and kinetic energy/5(36). In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.

Elastic potential energy is only present when a spring (or other elastic medium) is compressed or stretched. A simple pendulum does not consist of a spring.
