Faster means more energy

Inventors (Intermediate), mission I2 Energy on the Move, lesson 1 of 6.

Hook

A faster car has more energy. How could we prove it?

Fair test

Time the dragster over 1 m and 2 m for short and long pull-backs. Calculate the speed.

Bonus challenge

Build a paper-cup “crash barrier”. Faster car, bigger crash?

The build

  • 🔥 Big-Wheel Dragster: Giant back wheels, tiny front wheels — the same spring pushes this car much further! (level 2 of 5, about 22 minutes, 10 steps)
