Those are called Newton's cradle. It is a device that demonstrates conservation of momentum and energy.
The gravitational force between the two metal balls is 0.36 N.
To make Newton balls at home, you will need materials such as small metal balls, string, and a sturdy frame. First, attach the metal balls to the string evenly spaced apart. Then, hang the string from the frame so that the balls are able to swing freely. When one ball is pulled back and released, it will transfer its energy to the next ball, creating the classic Newton's cradle effect.
A sound is produced when a metal blade called a tangent strikes the string.
The metal part of a pencil is called a ferrule.
The word you are looking for is "engrave." It refers to the process of cutting or carving a design onto a hard surface, typically metal, by using a sharp tool.
They are typically called "stress balls" or "fidget balls."
Newton's Cradle
Bearings reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. The smoothness of the metal reduces the friction and the surface area.

A musket fires small metal balls (back then made of lead) called musket balls (simple enough:)
Rub my metal balls or rubber balls.
Metal wheels or the large Balls. They are 2 different types of things.

Close. It is BOULES.
The original barbell must be metal. After that...it's your preference. I don't like plastic barbells because they aren't as sturdy. However, I do like to use plastic balls instead of metal. The metal click against my teeth and can be more damaging.
I'm sorry, but that cannot be called metal, as the sound resembles bam's balls being cut off.
