How is tug of war related to pushing a refrigerator? Here's a simulation connects these two activities with Newton's First Law of Motion. Four different simulations allow scholars to explore net force with tug of war, motion with pushing...

Set youngsters in motion when studying forces. This quick animated film stars Sam and Mia, two intelligent but cool kids who talk about forces and motion on the soccer field. Consider using this resource when preparing junior-high...

Become a pinball wizard by understanding acceleration. Mia and Sam define acceleration for the audience and touch on the property of inertia. Get your physical science class up to speed by showing this little video, reviewing the...

Keep calm and use the force! Joey pulls a cart and scholars adjust the force required to control the movement. Through simulating different scenarios, participants learn about Newton's Third Law. It includes analysis questions throughout...

Why do sprinters wear spiked shoes? Scholars explore various styles of shoes and how they handle forces when running. Scholars adjust variables including shoe type, horizontal force, surface type, and normal force to determine which...

How does the soda clerk know exactly how to get the glass across the counter to the customer? Pupils use the simulation to adjust the launch velocity, glass weight, base area, surface material, and the customer's position to answer...

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...

Everything that happens is an interaction, from the wind blowing a sail to a cannon ball being thrust out of a cannon. A simulation shows the interactions involving a sail, air, ball, pirate, cannon, deck, ocean, and the Earth and...

Use your knowledge about friction to help Carrie get to the Invigatron before someone steals it. Following the activity, read more about friction and resistance, and then take a quick quiz to check for understanding.

A simple demonstration using a person on a bicycle to illustrate how thrust and resistance balance to achieve a constant rate of speed.

This simulation of a pendulum will demonstrate how friction and force have to change to keep the mass in the same position on the pivoted rod.
