Do mass or initial angle affect the period of the pendulum? Do they affect the pendulum's total time?ĭid the longer pendulum have a longer period than the shorter pendulum? Was the longer pendulum's period not quite twice as long as the shorter pendulum's period?Ī pendulum's period is related to its length, but the relationship is not linear. Extra: Instead of changing the length of the string, change the number of weights attached to the string or the initial angle of the string.What is the total time that each pendulum swings? Extra: Instead of timing the period of the swing, you could time how long each pendulum swings before it comes to rest.Is the period of the longer pendulum longer or shorter than the period of the shorter pendulum? How different are the two periods? Is this what you expected?.Are the periods consistent for each pendulum or do they vary a lot? Time the periods of the shorter and longer pendulums a few more times.

How long does it take the shorter pendulum to swing back to its original position? Drop the shorter pendulum and, once more, have the assistant time the period of the pendulum.

Have the assistant reset the stopwatch.

Again, pull the strings tight and hold them at the same angle from the meter stick.

How long does it take the longer pendulum to swing back to its original position? This is the period of the pendulum.

If the pendulum hit anything as it swung, such as the wall, readjust your setup and try timing the pendulum again. Then have the assistant stop the stopwatch when the pendulum returns back to its original position. Drop the longer pendulum and, at the same time, have the assistant start the stopwatch. Have an assistant ready with a stopwatch.Pull the strings tight (by holding on to the washers or pennies at the ends) and position the strings at the same angle from the meter stick.Tip: If the meter stick does not seem to stably sit on the backs of the chairs, you can try to tape the ends of the meter stick to the chairs.

Alternatively, if you are using pennies and tape, securely tape three pennies to the free end of each string.

Tie five metal washers to the free end of each string.

Space the strings about 20 to 30 cm apart on the meter stick. Tie one end of both strings to the meter stick, toward the middle of the stick. Cut a second piece of string to a length of 35 cm.

Cut one piece of string to a length of 70 centimeters.

Lay the meter stick on the backs of the two chairs, centered on the back of each.

Ten metal washers of identical size or six pennies.

The period of the pendulum depends on the force of gravity, as well as the length of the pendulum. For example, this is the time it takes a child being pushed in a swing to be pushed and then return back for another push. The time it takes a pendulum to swing back to its original position is called the period of the pendulum. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it. When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. In the example of the playground swing, the swing is supported by chains that are attached to fixed points at the top of the swing set. Other factors, including a pendulum's length, can also affect its motion.Ī pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. But pendulums can do more than provide fun at recess and help tell the time-among other scientific applications, they can show that the earth is huge! This is because the swinging motion of a pendulum is due to the force of gravity generated by the earth's size. We see pendulums in other areas of our lives as well, such as in grandfather (also known as longcase) clocks. Requires 4 AA batteries (not included).Did you know that playground swings can provide a good lesson in physics-as well as lots of fun? The back-and-forth motion of a swing is an example of a pendulum.

Thick, high-grade piece of glass protects the metal clock face & design of the cogs. While the pendulum swings every second, adding to its charming appeal. Exposed gears rotate to fuel the rhythm of the clock's slender black hands, leaving admirers mesmerised and in a hypnotic state as they watch the gears rotate in perfect unison. The frame is made of pure metal with an antique rustic washed metal finish. The unpolished look provides a neutral aesthetic, while the visible inner mechanisms and cut out details provide visual interest. The Antique configuration of this elegant pendulum wall clock puts the popular in mechanics.
