Stretching and Bending: Understanding Deformations and Forces on Objects

The video tutorial explores the effects of forces on objects, focusing on how forces can change an object's shape or size through bending, stretching, or compressing. It distinguishes between elastic and inelastic deformations, providing examples with springs. The concept of extension is introduced, explaining how to measure the change in length when forces are applied. The tutorial emphasizes the need for at least two forces to cause deformation and provides practical examples to illustrate these concepts.

What happens to an object when we apply a force to it?

Describe a situation where a force causes an object to rotate without changing its shape.

How can we change the shape or size of an object using forces?

Explain the difference between elastic and inelastic deformation.

What is extension and how is it calculated?
