### 6 Animations ### acceleration01.iwp

Play the animation to view an object moving horizontally across the screen. Its acceleration is uniform. Step through the animation and take measurements of x-position and time to use for finding the acceleration. The object enters the field of view at -10.0 m and leaves (momentarily) at +10.0 m. Tic marks are placed every meter. Read positions of one side of the object to the nearest 0.1 m. ### dvat-10.iwp

Play the applet to show a position vs. time graph of an object having the given initial velocity and acceleration. Sketch your predictions for the shapes of the corresponding velocity vs. time and acceleration vs. time graphs. Then click on Show graph to check your predictions. ### kingraph1.iwp

Play the applet to show a position vs. time graph of the blue dot. In your notes, sketch your predictions for the shapes of the corresponding velocity vs. time and acceleration vs. time graphs. Then click on Show graph to check your predictions. ### projectile-template-2.iwp

A projectile is launched at an angle from a cliff. A target moves at 0, constant, or uniformly changing velocity. Hit the target with the projectile. Velocity vectors are shown on the projectile. ### velocity01.iwp

Play the animation to show a position vs. time graph of a uniformly-accelerating object. The blue line remains tangent to the path of the object. Therefore, the slope of the blue line is the instantaneous velocity of the object. Its value is given above the play buttons. Predict how graphs of velocity vs. time and acceleration vs. time will appear. Then click on Show Graph to display a velocity vs. time graph of the motion. Click on yAccel in the Graph window to show the acceleration vs. time graph also. ### velocity03.iwp

A position vs. time graph of a uniformly-accelerating object is shown. The blue line is always tangent to the path of the object. Determine the acceleration of the object by doing the following: 1. Visually read coordinates from the graph to use in determining the slope of the line at times of 0, 2, 4, 6, 8, and 10 s. Record your values in a table. 2. Plot a graph of of velocity vs. time and draw the best straight line through the data points. 3. Find the slope of the velocity vs. time graph.
