Oobleck is an example of a fluid whose viscosity is not constant; itâs viscosity changes depending on the stress or forces applied to it. If you poke it with your finger and apply a large force, it becomes very viscous and stays in place. If you gently pour it, applying little force, it will flow like water.
The camera angle marks the specific location at which the movie camera or video camera is placed to take a shot. A scene may be shot from several camera angles simultaneously. This will give a different experience and sometimes emotion.
Focal length is the distance between the center of the lens and the image sensor. By moving the lens farther from the image sensor inside the camera body, the zoom increases because a smaller portion of the scene strikes the image sensor, resulting in magnification.
