This is a simulation to illustrate the one dimensional constant acceleration (gravitation g=10m/s[sup]2[/sup], it can be changed with slider)

1.You can use sliders to change the initial position(yi), velocity(Vy_i) or even the gravity (g).

2. Click Play (right triangle) to start the simulation. The simulation will paused when y
3. You can change t1 with slider to find out
 V(t1)=V[sub]0[/sub] - g*t1;
 average velocity V[sub]avg[/sub](0-t1)=(V[sub]0[/sub]+V(t1))/2= V[sub]0[/sub]-g*t1/2;
 distance traveled =V[sub]avg[/sub](0-t1) * t1=(V[sub]0[/sub]+V(t1))*t1/2
4. You can drag slider t2 to find out similar information for t2 (t2>t1) , and find out distance traveled between t1 and t2,too!
