gMeter is an app that turns the iPhone, iPad, and iPod Touch into a vehicle performance computer. By using the onboard accelerometer in these devices, gMeter can measure forward and lateral g forces and use this data to compute acceleration, velocity, distance traveled, and engine power.
"Gamification is a powerful way to engage students in the science and math classroom. The Universe and More, a nonprofit company founded by a high school teacher, has released a new game called Action Graphing. This iPad app helps students understand key concepts related to graphing. Students will learn how to analyze and interpret graphs to model the motion of real objects. They'll see how the slope of the line represents an object's velocity and the y-intercept of the line represents the object's position."
