Scholars focus on associating balanced forces with at rest or constant velocity motion and unbalanced forces with acceleration or deceleration. Practice problems with immediate feedback allow for quick success in an installment of the...

Scientists use many different kinematic representations of motion. Review each of them with the help of an engaging interactive that is part of a larger series on Newton's laws of motion. The resource provides three levels of challenge...

How does an airplane control its take off and descent? Scholars explore the forces acting on an airplane and control the angle of attack, wing profile, thrust, and airplane size. They learn about lift, drag, thrust, gravity, and the...

Use science inquiry to predict and investigate forces and motion to help rescue Ruff's plushie from the penguins' ice rink in this sports science game.
