How to make parabolic animation with PPT

A physical PPT Courseware animation production method, to help you understand and learn the PPT 2003 animation production function.

PPT Animation Tutorial: The bomb's flat throw movement

In the high school physics "flat throw movement" teaching, needs to demonstrate from the horizontal flight plane to cast the bomb the trajectory, as well as many bombs and the airplane position relations. Now let's make this PPT courseware together.

1. Insert an object into a slide

In order to make the courseware more vivid and intuitive, we need to insert the pictures that have been made into the slides. If the picture you put on the slide is not the right size, you can select it, and then drag the sizing handles around the picture to change the size of the picture. Similarly, if you want to adjust the placement of the slide picture, you can move the picture by dragging the mouse as long as it is selected.

2. Define the motion path of the object

According to the requirements of PPT courseware making, the plane in the picture is horizontal and uniform. The way to define this motion path is: Select the plane that has been inserted into the slide, open the Add Effect menu in the PPT2003 Custom Animation task pane, click the Right command under the Motion Path submenu, start with the green triangle, and a red triangle to draw a horizontal line for the end point. Where the green triangle is the starting position of the object (airplane) animation, the red triangle is the ending position of the object (airplane) animation, and the horizontal dotted line is the object's motion trajectory. If you think the default "motion path" length is not appropriate, you can select the triangle and horizontal dotted line that represents the action path, and then drag the handle on the red triangle to change its length.

The next step is to define the bomb's motion path, and the action method is still to select the bomb that slides into the slide, open PPT2003 the Add effect/motion path/Draw Custom Path submenu in the Custom Animation task pane, click the Curves command. When the cross cursor appears, the curve can be drawn from the place where the bomb is located.

Note that: During the drawing process, click the mouse once to leave a "vertex", the line can be at the center of the point arbitrarily curved, you can draw a relatively smooth curve. Finally, draw the curve below the end of the aircraft animation, double-click the mouse to end the drawing of the curve. If you feel that the curve you are drawing is not smooth enough, you can right-click the curve with the right mouse button. When you select the edit Vertices command on the shortcut menu, many small black dots appear on the curve (which is where you click the mouse when you draw the curve), and you can drag a vertex with the mouse to make the curve smoother. Finally, according to the method described above, place two bombs at the position below the end of the plane, as shown in the picture, to show the law of the bombs being placed in a straight line below the aircraft after the bombing.

3. Define the object's action time

Because the plane in the picture is horizontal and uniform. And the bomb in the horizontal direction of the straight line, in the vertical direction of the freefall, its synthetic movement trajectory is parabola, each moment the bomb's position is under the aircraft. So the first bomb and the aircraft should start at the same time, set the first bomb on the slide, and then open the Drop-down menu in the Custom Animation task pane, and select Start from Previous. In order to achieve the aircraft in the horizontal direction of flight, and bombs in the air for parabolic movement effect.

Then you can set the second to third bomb to appear in the way and the time. For simplicity, you can set the plane to appear when it flies to the finish position. You should hold down the CTRL key to select both bombs, open the Add Effect/Enter submenu in the Custom Animation task pane, and click the appear command. This setting allows the aircraft and the first bomb to reach the finish line, and the second to third bomb immediately appears under the aircraft effect.

After that, you can click the "Play" button in the PPT to see the actual effect of the animation. If there is anything you don't understand, you can leave a message to ask, and if necessary, I can record a video tutorial.
