Physics Introduction to Statics and Dynamics: Forces and Newton's Laws - Contact Forces Part 2

This video tutorial explores the properties of contact forces, including compression, tension, shear, and elastic forces. It explains the concepts of systems, external and internal forces, and how they interact. The video uses examples like Lotus on a stool and a party popper to illustrate these forces. It also discusses ideal objects and their simplified properties for easier analysis.

Define an ideal object in the context of physics.

Explain the concept of elastic force and provide an example.

How do internal forces contribute to the stability of a system?

What role does the normal force play in preventing objects from passing through each other?
