Experiment⭐ 30 XP⚡ Spark LabSpeed, Velocity, and Acceleration (Part 3)
Simple Electricity.
🎯 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
Speed measures how fast an object moves (distance divided by time). Velocity includes both speed and direction. An object changing direction is accelerating even at constant speed.

Question 1
1 of 3What is velocity?
Where you see this in real life
This is why airplanes can fly and why rockets reach space.
Stretch Challenge
Try this in real life this week.
This week, find one thing in your house that turns one kind of energy into another.
For the dinner table
“Show me something at home that uses this kind of energy.”
