Materials (i assume you mean clothes of fabrics) are stretchy due to the amount of elastic in the fabric. More elastic means stretchier fabric, less elastic means it will not be as stretchy.
A stretchy material is a fabric that can be stretched or expanded without losing its shape. Materials like spandex, elastane, and Lycra are commonly used to add stretchiness to clothing items such as activewear, leggings, and swimwear.
i learnt this in year 7 so basically the particles in an elastic band are in the form of a zig-zag. they are like a solid, joint together. when you stretch the band, the particles stretch. they form a straight line. i hope this answers ur question x
The material and process that determine what makes a permanent magnet is the alignment of magnetic domains within the material. When these domains are aligned in the same direction, the material becomes magnetized and exhibits magnetic properties.
A hair elastic is a small, typically round band of stretchy material, such as rubber or fabric, used to gather and hold hair in place. It is commonly used in hairstyles to secure ponytails, braids, and buns.
The type of matter that makes up an object is called its material, and its arrangement within the object is its structure. The material determines the properties of the object, while the structure dictates how the material is organized and interacts. Together, material and structure define the physical characteristics and behavior of the object.
probably the polyester
flexible and stretchy
it is stretchy
Yes.

silk is usually stretchy and it makes long dresses.
A cotton is soft and a cotton jersey is soft Jersey. Cotton is a woven fabric. It is not stretchy. Cotton jersey is a knit. It is stretchy like t-shirt material.
B/c a bit of stretch makes it gentler on the body to be caught by the belts in case of an accident. If they were entirely rigid, the stop would be more sudden and hurt more.
Material B would make the best swimwear as its absorbent properties would help with water absorption and quick drying, which is essential for swimwear. The lack of stretch in Material B can be compensated for by using a design that provides a good fit and comfort for the swimmer.
gum is made stretchy because of polymer bonds. some gum is stretchier then other, for example bubbleicious is stretchier then orbit and this is because bubbleicious has a longer polymer chain then orbit
Cotton itself is not a stretchy fiber. Woven fabric is typically not stretchy. So no, I would not expect a cotton gauze to be stretchy unless it was a cotton blend.
Sticky hands are usually made from a stretchy rubber or silicone material that has a tacky surface. This stickiness allows the hands to adhere to surfaces and objects when thrown or pressed against them.
