A swinging Foucault Pendulum will change its direction 360° over a 24-hour period as Earth rotates on its axis. The motion of the pendulum is independent of Earth motions. The pendulum actually swings in the same direction it is Earth that rotates beneath the pendulum.

Pendulums move in accordance with Newton's laws of motion, and the force of gravity.

answ2. Pendulums are free to move in directions other than side to side. The balance wheel in a mechanical watch is an example of rotary oscillation.

Indeed one cannot limit the motion of a pendulum as "from side to side", for an ordinary mass hanging on a long string will precess throughout the day. [There used to be a marvellous one in the Smithsonian - a popular exhibit. Foucalt pendulum.].

And an interesting speculation is why does the mass disappear from the equation. As expressed in the 'l/g' expression, one might be led to believe a mass-less pendulum would resonate! The disappearance of mass in the math does not infer that a mass-less pendulum would work.

{For a demonstration of oscillation, we used to suspend a small mass on an elastic cord (a rubber band). This device has several different periods, depending on the particular oscillation.

a) The up-and-down oscillation demonstrates the principle of vibration isolation - (just vary the frequency of your oscillatory input);

b) an ordinary simple pendulum;

c) a pendulum where the mass describes a circle of rotation, with the string describing the surface of a cone;

d) and the 'watch-spring type of circular motion.

So with a single mass and a single spring, four different oscillations may be generated. [The trick is that the spring force is of a different nature in each case. And the centroid of mass alters also!]}

-- A moving object doesn't need any force to keep it moving.

-- The speed, or direction, or both, of a moving object is changed

by any force that's not cancelled by another equal opposite force.

What is a pendulum bob?

The bob is the weight on the end of the pendulum.


Does the distance a pendulum travels decrease with each arc?

if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.


A certain pendulum has a potential energy of 20 J when it is at the top of its swing. What is the kinetic energy?

If at the top of the swing the pendulum is STOPPED then it has zero kinetic energy.

Why does a swinging pendulum lose energy once it is set into motion?

When a pendulum is released to fall, it changes from Potential energy to Kinetic Energy of a moving object. However, due to friction (ie: air resistance, and the pivot point) and gravity the pendulum's swing will slowly die down. A pendulum gets its kinetic energy from gravity on its fall its equilibrium position which is the lowest point to the ground it can fall, however, even in perfect conditions (a condition with no friction) it can never achieve a swing (amplitude) greater than or equal to its previous swing. Every swing that the pendulum makes, it gradually looses energy or else it would continue to swing for eternity without stopping. Extra: Using special metals that react little to temperature, finding a near mass-less rod to swing the bob (the weight) and placing the pendulum in a vacuum has yielded some very long lasting pendulums. While the pendulum will lose energy with every swing, under good conditions the amount of energy that the pendulum loses can be kept relatively small. Some of the best pendulum clocks can swing well over a million times.

How does the period of a pendulum related to how hard the pendulum is pushed?

It shouldn't relate at all. The period of a pendulum depends only on its length, not on how far it swings side-to-side.

Will a pendulum swing on the moon?

I think it will as it has mechanical parts to make the pendulum move, not 100% sure.


What changes can you make to affect the pendulum so that it can swing more or less swings in 15 seconds?

You can affect the pendulum to move down or up and it will be will might be 11 or 12 seconds because of the length and how you want the pendulum for it to move.

How does the mass of pendulum affect its period?

well, you could simply pull it away from its centre of equilibrium (the point where the pendulum is when its stationary), and release it. Then you just count how many seconds it takes to make one complete oscillation. Note, one oscillation isn't the time for the pendulum to swing to the other side, but is the time taken for the pendulum to return to the side it was initially released from.Note: the greater the angle of the swing, the greater the speed with which the pendulum will swing, but in the absence of air resistance, the period should remain the same with the same pendulum, and because air resistance is all around us, when we move through the air, and is proportional to the speed squared, this will begin to effect the result, by slowing down the pendulum. Therefore a pendulum only obeys SHM for smaller displacements from the point of central equilibrium, or another way of putting that is for smaller angles of pendulum displacment.
