Auntie CeCe's Engineering Science Course: What a Force Is: Weight, Mass & Gravity | Lesson 3

Lesson 3 of 12 in Auntie CeCe's Engineering Science Course, Part 1 (the basics). We learn what a force is: pushes and pulls, drawing forces as arrows, the newton, contact and non-contact forces, gravity, mass versus weight with W = mg, spring balances, balanced and unbalanced forces, and the normal reaction. In this lesson: A Force Is a Push or a Pull; What Forces Do; Drawing Forces as Arrows; The Newton; Contact and Non-contact Forces; Gravity; Mass vs Weight; Worked Example: Weight; Same Mass, Different Worlds; Measuring Force: the Spring Balance; Balanced and Unbalanced Forces; The Normal Reaction; Auntie's Recap. There's a 3-question quiz at the end (pause and work it out), then the answers and the course path. This course is general education. Follow your own syllabus, your instructor, and local codes for any real design work. #EngineeringScience #AuntieCeCe #LearnEngineering
