Those are called Newton's cradle or Newton's balls.
As far as I know they have more to do with Newton's law that every action has a opposite and equal reaction. As far as them telling time it may have to do with the pendulum and how long each period (swing) is.
The inverted giant swing is called a Reverse Hecht.
The item you are describing is called a Newton's Cradle. It is a device that demonstrates the conservation of momentum and energy through a series of swinging spheres. When one ball is pulled back and released, it transfers its momentum through the stationary balls, causing the opposite ball to swing out in response.
To create a Newton's Cradle project, you will need to follow these steps: Gather materials: You will need five metal or plastic balls of equal size, a sturdy frame to hold the balls, and string or wire to connect the balls. Attach the balls: Use the string or wire to attach the balls in a straight line, making sure they are evenly spaced and can swing freely. Set up the frame: Place the frame on a flat surface and ensure it is stable and secure. Test the project: Pull back one of the balls and release it to see if the kinetic energy transfers through the balls, causing the opposite ball to swing out. Adjust as needed: If the balls are not swinging properly, adjust the spacing or the tension of the strings to achieve the desired effect. Enjoy your Newton's Cradle: Once everything is set up correctly, you can enjoy watching the mesmerizing back-and-forth motion of the balls as they demonstrate the principles of conservation of momentum and energy.
The bottom of the pendulum swing is called the equilibrium position.
Hitting with flat tennis balls doesn't necessarily hurt your strings all that much, but it definitely hurts your game. They can hurt your strings a little if you are using all of your might to swing into the tennis ball, and because it is flat the ball will flatten out over the strings and cause more areas of the string to become weaker.

This all depends on your swing speed my friend. Harder balls go farther for a person with higher swing speeds and softer balls go further for those individuals with lower swing speeds.
it is called " a ball" 4 balls and the batter walks to 1st base.
A batter is awarded 1st base after four balls are pitched outside the strike zone that they do not swing at. This rule is part of baseball's guidelines regarding balls and strikes. If a batter receives a fourth ball, they can advance to 1st base without the risk of being put out.

well there is a queen and king with a rubber dingaling
It is called 'Swing' by Savage.
The way to swing a racket in tennis is called a forehand.
If it's on your porch, porch swing. If a regular swing then it's called, a swing couch.
The device with silver balls that knock one another is called a Newton's Cradle. It demonstrates the principles of conservation of momentum and energy through a series of swinging metallic balls. When one ball is lifted and released, it strikes the others, causing the ball on the opposite end to swing outward. This visually illustrates the concepts of physics in a simple and elegant way.
