Demonstration 1: Sketch on the axes on the right your predictions

for the x coordinate of the ball as a function of time and the y

coordinate of the ball as a function of time.

Only after you have made your predictions, click Position to display

a video with the Position-time graphs plotted out as the ball moves.

Compare the actualx and y position graphs to your predictions and

explain any differences.

Based on your graph of x vs. t, write a kinematic equation for x as a

function of time.

x =

Based on your graph for y vs. t, write a kinematic equation for y as a

function of time.

y=
