Use the Accelerometer to investigate Newton’s First Law.

Use Science Journal and the Accelerometer on your phone to test yourself: How little can you jostle the top block as you smack away the blocks beneath? Here you can get out your aggression as you conduct a hard-hitting investigation into Newton's First Law: An object at rest remains at rest unless acted on by a force. Experiment further by trying blocks of different size, density, and smoothness.
