Newton's Second Law: Force and Acceleration.
🎯 Your mission
Push the limits. See what changes.
⚡ 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
Newton's second law says that force equals mass times acceleration (F = ma). A heavier object needs more force to accelerate at the same rate as a lighter one.
Key Words
- Newton
- acceleration
Steps
Look at the vocabulary words and write a definition for each in your own words.
Test friction: pull a weighted box across 4 surfaces (carpet, tile, sandpaper, foil). Use a spring scale to measure the force needed for each.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
