What does the word rigid mean in science?

The term rigid in this context refers to an object that is firm, strong and not flexible. This term is most often used in reference to living organisms. A rigid body is one whose shape does not change when an external force is applied. A good example is a metal rod. When you push a metal stick to one end, the other end will also move towards the direction of the force. This is because the metal is not flexible. A human being is also a rigid body. Your body does

What does the word rigid mean in biology?

A living thing is said to be rigid if it has a structure which does not change when it is moved or stretched. A rigid cell wall is an example of a rigid structure. Plant cells are also referred to as rigid. Examples of rigid cell walls are the walls of grass, carrot, and potato cells. These walls help to keep the cell structure and content from bursting.

What does the word rigid mean in astronomy?

Everything in the Universe is either in a solid state or a gaseous state. A solid is made up of atoms that are held together by forces called chemical bonds. A gas is made up of atoms that are held together by forces called thermal motion. In a solid, the atoms have fixed positions relative to each other. In a gas, the atoms are free to move around as they like.

What does the word rigid mean in physics?

Rigid means something that does not change its shape or size under the action of forces. This is not to be confused with sturdy, which means strong, or solid, which means that it has a definite shape. A solid is not necessarily rigid, and a rigid body can be made of different materials. It is important that the same amount of force is applied on all sides of an object to determine whether or not it is rigid. If an object is able to withstand a certain amount of force without

What does the word rigid mean in chemistry?

In chemistry, a substance is said to be rigid when it has a high resistance to the flow of any internal or external energy, in the form of heat, sound, or electricity. That means a rigid substance does not change shape after being heated or cooled. If a piece of metal gets hot, it gets thinner and less stiff. If a piece of ice gets cool, it gets thicker and more stiff.
