Common Forces in Mechanics

The video tutorial explores common forces in mechanics, starting with gravity, which is a universal force holding objects in place. It then delves into contact forces, explaining their occurrence between objects and their components, such as normal reaction and friction. The tutorial also covers tension in strings and spring forces, highlighting the relationship between displacement and restoring force.

List some examples of contact forces mentioned in the text.

What is the relationship between displacement and spring force according to Hooke's Law?
