• No setup time.
• Very accurate and economical ball.
• Very easy to use to measure value of 'g'.
• Inbuilt two axis impact detection mechanism.
• Start/Stop/Mode switch (Act as Start, Stop function in stopwatch & to display time and height under free fall after impact in mode function).
• Auto Shutdown after 30 sec.
• Fun experiments.

The Timing ball is a unique device that records time from moment of release of ball to the moment of impact (on ground or object). It can be used to conduct a number of experiments involving acceleration due to gravity (g).

Calculation of Momentum
Calculate the velocity of the ball upon impact, using v = g*t where t is the time in seconds after it is dropped and g is acceleration due to gravity.
Calculate the momentum p of the ball upon impact, using p = m*v, where m refers to the mass of the ball.

Value of 'g' may be calculated using equation:
S= ½ gt²,
where S is distance in meter and t time taken in seconds.
