Simulation⭐ 30 XPBalanced and Unbalanced Forces (Part 2)
Balanced and Unbalanced Forces (Part 2).
🎯 Your mission
Play with the model. Break it. Understand it.
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
What You'll Learn
Balanced forces are equal in size and opposite in direction, so an object stays still or moves at constant speed. Unbalanced forces cause an object to accelerate or change direction.
Key Words
- voltage
- current
Steps
Read the introduction and identify the main idea of this lesson.
Test friction: pull a weighted box across 4 surfaces (carpet, tile, sandpaper, foil). Use a spring scale to measure the force needed for each.
Look for patterns in your observations.
Make a graph or chart showing your results.
