Sir Isaac Newton, so the story goes, was hit on the head with an apple, thus giving birth to his theory of gravity...but apples are SO 17th century! Students can use this clever device to easily study the effects of gravity. A digital timer in the center of the G-Ball measures the amount of time the ball is in the air, to the hundredth of a second. The timer begins when the button on the display is released, and it stops when the ball is caught or it hits a surface (maximum 12 meters - about three stories - when dropped onto a fairly soft surface). Students can throw the ball straight up, horizontally, or simply let the ball drop to calculate the height, velocity, or magnitude of gravitational acceleration. This is a fun way for students to master the concepts of gravity. Two LR1130 batteries included. Diameter 10 cm (~4").Products being sold are not toys. They are for Educational / Laboratory use only.
