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.
