We’re excited to add another simulation to our Basics series, designed specifically with middle-school students in mind.

With the new Forces and Motion: Basics simulation, explore the forces at work in a tug of war or by pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.
