First Law Simulation
Does Newton's First Law of Motion explain how to move a sled across ice? A simulation encourages scholars to decide if they should push, pull, or apply no force. Their decision moves a sled across the ice and to the home at the...
CK-12 Foundation
Friction Simulation
How much pulling force does it take to overcome static friction? The simulation applies the formula for the force of static friction to multiple trials. Scholars alter the pulling force applied until the box moves. They then determine...
