Year 9 Flash Homework 1

Explanation
A motion tween refers to the automatic movement of an object from its initial position to its final position. It does not involve changing the color or physical characteristics of the object.

Explanation
A vector graphic does not use a matrix of dots or pixels to define the image. Instead, it uses mathematical formulas and coordinates to create shapes and lines. This allows vector graphics to be easily scaled and resized without losing any quality.

Explanation
If we have transparency in our image, we should save it in the PNG format. PNG (Portable Network Graphics) supports transparency, allowing us to save images with a transparent background. Unlike JPG, which does not support transparency, PNG preserves the alpha channel, making it ideal for images that require transparency such as logos, icons, or graphics with complex backgrounds.

Explanation
Vector images can be enlarged without losing quality because they are created using mathematical equations and geometric shapes, rather than pixels. This means that when a vector image is enlarged, the computer recalculates the mathematical equations to create a larger version of the image, resulting in a smooth and sharp image at any size. On the other hand, bitmap images, such as PNG, are made up of a grid of pixels, and when they are enlarged, each pixel becomes larger, resulting in a loss of quality and pixelation.

Explanation
An animation created with vectors will generally have a smaller file size than one created with bitmaps because vectors use mathematical equations to define shapes and lines, while bitmaps use individual pixels to create an image. This means that vectors can be scaled and resized without losing quality, whereas bitmaps can become pixelated when resized. Additionally, vectors only store information about the shapes and lines used in the animation, while bitmaps store information about each individual pixel, resulting in a larger file size. Therefore, animations created with vectors are more efficient in terms of file size.

Explanation
The keyboard shortcut F6 is used to insert a keyframe.

Explanation
To insert a regular frame, we use the F5 keyboard shortcut. This shortcut allows us to quickly add a new frame to our document without the need to navigate through menus or use the mouse. By pressing F5, we can efficiently insert a regular frame wherever we need it in our work.

Explanation
Ctrl-Z is the correct answer because it is a commonly used keyboard shortcut to undo a mistake. When we make a mistake, pressing Ctrl-Z allows us to revert back to the previous action or remove the mistake. This shortcut is widely used in various software applications and operating systems to provide an easy and quick way to undo errors or changes.

Explanation
Ctrl-Enter is the correct keyboard shortcut to preview animations. Pressing Ctrl-Enter allows us to quickly preview our animation without having to play the entire timeline. This shortcut is commonly used in animation software to provide a quick and convenient way to review and make adjustments to the animation in real-time.
