Forces That Cause Change

The video explores the concept of force, defined as a push or pull in a specific direction. It explains how force can change an object's shape, speed, and direction, affecting its velocity. The video discusses deformation, distinguishing between elastic deformation, where objects return to their original shape, and plastic deformation, where they do not. It introduces the concepts of elastic limit and rupture point, using examples like elastic bands and springs. The video concludes with a trampoline example to illustrate these concepts and advises against testing limits at home.

What is a force?

• A type of energy

• A push or pull in a specific direction

• A measure of mass

• A form of acceleration

Which of the following is NOT an effect of force?
