Multiple Choice Questions: Simple Animation in Scratch for Computer Science

📚 Quick Study Guide

• 🐱‍💻 Scratch Basics: Scratch is a visual programming language where you drag and drop blocks to create animations, games, and interactive stories.
• 🎬 Animation Principles: Key concepts include using costumes, loops (repeat blocks), and changing x and y coordinates to move sprites.
• 🔄 Loops: 'Forever' and 'Repeat' blocks are essential for continuous or multiple actions.
• 🎨 Costumes: Sprites can have multiple costumes. Switching between costumes creates the illusion of movement.
• 📍 Coordinates: The Scratch stage uses x and y coordinates. X changes horizontal position, and Y changes vertical position.
• ⏱️ Timing: Use 'wait' blocks to control the speed of your animation.
• ➕ Variables: Useful for storing and changing values, such as score or animation speed.
