  1. Measuring Movement Aims You should be able to; Measure velocity and acceleration using ticker timers. Measure velocity and acceleration using light gates.

  2. Using Ticker Timers The unit works by using an electromagnet which pulls a pin down onto a carbon disc and thence through to paper tape. The unit produces 50 dots per second and from the resulting pattern the velocity or acceleration of the tape may be calculated.

  3. Using Ticker Timers What motion is indicated by these ticker tapes ? 1) 2)

  4. Using Ticker Timers How do we calculate velocity using a ticker timer ? 1) 20 cm 2) 20 cm

  5. Using Ticker Timers How do we calculate acceleration using a ticker timer ? Measure x . Work out the initial velocity. Measure y . Work out the final velocity. Measure N . Use v2 = u2 +2as to find a.

  6. Using Light Gates How do we calculate velocity using light gates ?

  7. Using Light Gates How do we calculate acceleration using light gates ?
