Experiment⭐ 30 XP⚡ Spark LabInclined Planes and Ramps
Inclined Planes and Ramps.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
The opposite of what you expect is often what happens.
Mind = Blown
🔥 A bolt of lightning is 5 times hotter than the surface of the sun.
Make a hypothesis first
Predict: what happens if you double the force?
What You'll Learn
An inclined plane is a flat, slanted surface, like a ramp, that makes lifting easier. Pushing a load up a gentle slope takes less force than lifting it straight up, though you must move it a longer distance.

Look for patterns in your observations.
Make a graph or chart showing your results.
