Portable timer for Photogates and Smart Pulleys

Measures Time, Speed and
Acceleration  

Measure Time

One gate : returns time from leading edge to leading
edge

Fence: returns 10 time values

Tow gate : returns time between 2 gates

Pendulum : measures pendulum period

Stopwatch

Measure speed

One gate : single object speed using picket fence

Collision: lnitial and final speeds for 1 or 2 carts

Pulley : angular speed radians/second or in
revolutions/second

Measure acceleration

One gate : direct mrasurement of acceleration using
picket fance

Linear pulley :acceleration of string tangent to segye
pulley

angular pulley

tow gates : object”s average acceleration between 2
photogates

Measure counts : 0~9,999,999 total counts
