##### 1 D motion in gravitation field (constant acceleration a=gravity)
« on: October 10, 2009, 02:48:31 pm »
This is a simulation to illustrate the one dimensional constant acceleration (gravitation g=10m/s2, 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)=V0 - g*t1;
average velocity Vavg(0-t1)=(V0+V(t1))/2= V0-g*t1/2;
distance traveled =Vavg(0-t1) * t1=(V0+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!
