Why do pendulum clocks stop?
The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location. A clock is "in beat" when the tick and the tock are evenly spaced.
Do shorter pendulums swing faster?
Shorter pendulums swing faster than longer ones do, so the pendulum on the left swings faster than the pendulum on the right. What affects a pendulum? The mass and angle are the only factors that affect the period of a pendulum. b. The mass, the angle and the length are the three variables affecting the period.
What can be a pendulum?
A pendulum is any object which has a string or a chain of metal or leather attached to it and swings back and forth or in a circular motion. What is a pendulum? They can be made up of a variety of elements including crystals, wooden, glass or metals and come in all shapes and sizes. How long will a pendulum swing?
How do you find the potential energy of a pendulum?
Energy in a Pendulu. GPE can be calculated by multiplying the mass, the acceleration due to gravity, and the height change. Once the mass is let go, it starts to swing. Kinetic energy (KE) is the energy of motion, and is the product of one-half the mass, and the square of the velocity (v) in m/s. Thereof, when the pendulum is furthest up what is its only energy? Assuming no friction, when the pendulum is at its highest point, it is at rest and has only gravitational energy. When it falls, it loses gravitational energy and turns it into kinetic energy, which allows the pendulum to swing back up 20 cm on the other side.

I didn't know that pendulum clocks don't need batteries. It may seem like it's idling around, serving no purpose as it swings to and fro, but that action is what keeps the clock accurate to the second.
- Why do clocks have pendulums?
The advantage of a pendulum for timekeeping is that it swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. Most Pendulum clocks are kept for their decorative and antique value. Pendulum clocks have to be stationary to operate.
- What is the effect of the second pendulum swings onto the first pendulum?
The first pendulum is pulled back as soon as the second pendulum swings. The first pendulum slows down when these pulls are timed. It may help you to think of a playground swing.
