It's possible to change one of input data one after another. Thus it's possible to get output data which correspond to changed input data.
(Example)
A first ball of mass 1 Kg is moving with the velocity 1 m/s, and second ball of mass 2 Kg is stationary. Calculate the velocities of both ball after collision.
When the first ball velocity is changed to 0.9, 0.8, and 0.7 m/s, calculate the velocities of both ball after collision.
Assume that coefficient of restitution is 0.5.
(Answer)
Enter as follows,
e = 0.5
M1 = 1, V1 = 1
M2 = 2. V2 = 0
Touch out P button that corresponds to the data which is planning to be changed.
We are planning to change the velocity of the first ball.
Touch out V1_P button.
We obtain 0.0 m/s and 0.5 m/s as the final velocities.
Delta data is attached to the V1 data as an increment.
Enter as follows.
Delta = 0.1
Touch out - button of the V1 data. V1 data is decremented.
We obtain 0.0 m/s and 0.45 m/s as the final velocities that correspond to the first ball velocity 0.9 m/s.
Next touch out - button. We obtain the next output data.
