Exploring Weight and Spring Forces

The video tutorial discusses different types of forces, including contact and non-contact forces. It explains weight force and its relation to gravity, as well as spring force described by Hooke's law. The tutorial also covers Newton's laws and demonstrates problem-solving using these concepts, focusing on calculating spring constants and understanding force interactions.

What are the two main categories of forces?

• Gravitational and electric forces

• Push and pull forces

• Weight and tension forces

• Contact and non-contact forces

Which of the following is an example of a non-contact force?

• Normal force

• Gravity

• Tension

• Friction
