About This Product
A trolley or falling mass pulls tape through the timer, and the spacing of the dots shows how far it moved in each fixed interval. Students measure the gaps to work out velocity and acceleration and build velocity-time graphs for kinematics and Newtonian dynamics experiments.
Frequently Asked Questions
How many dots per second does the Ticker Tape Timer, AC Type make?
It marks 50 dots per second on a 50Hz supply and 60 dots per second on a 60Hz supply, because it is synchronised to the mains frequency.
What voltage does it need?
It runs on 12V AC, connected through two colour-coded 4mm sockets.
