📦 Load and Center of Mass
Explore how weight (load) acts on structures and why the position of that load matters. Learn about center of mass, how to predict when objects tip over, and how to distribute weight safely for better stability. This quiz covers essential Grade 5 physics concepts for understanding real-world structures and mechanisms. What you'll learn: - Define load (weight) and identify how it acts on structures - Explain what center of mass means and locate it in common objects - Predict how load placement affects an object's stability - Apply load distribution principles to prevent tipping - Analyze which structural designs can handle different load conditions
