Question

Give some examples of internal forces?​

Answer 1

The forces that work inside the surface of the Earth are known as Internal Forces.

• The internal forces are also known as Endogenic Forces.
• These forces form pressure bounded within the surface of the Earth.
• The internal forces are types of forces that govern various horizontal and vertical types of movements of the Earth.
• These motions lead to various geographical events of folding and faulting, upliftment of land, volcanism, etc.

Some of the examples of Internal Forces are:

• One major example of Internal Forces is the Tectonic Plate movements.
• Another example is causing and formation of Earthquakes.
• Other examples include volcanism as well.

Answer 2

Answer:Examples of internal forces are frictional force, applied force, normal force, tensile force, air resistance, etc.

Explanation:

A force that acts on an object from outside is called an external force. Any force that acts on a structure from the inside is called an internal force. Two or more objects that interact together form a system. An external force arises as a result of the interaction between the system and its surroundings. On the other hand, an internal force is an interaction that exists in a system. External forces cause motion in an object, while internal forces prevent motion. Work is said to be done when an external force acts on an object, while work done due to an internal force is zero.

Examples of internal forces are frictional force, applied force, normal force, tensile force, air resistance, etc.
