PPT animation of satellite orbiting the Earth

The PPT animation of the satellite movement around the earth is often used in our daily lessons, and now we are working together to make a PPT animation of the satellite revolving around the Earth.

1. Put "Earth" and "satellite" into slides

First open the PPT2003 or PPT2007 Drawing toolbar, shift-click the Oval button on the toolbar, and drag the mouse to draw two circles of varying sizes in the slide. The larger circle placed in the middle of the slide represents "the Earth", placing a smaller circle at certain intervals from Earth to indicate "satellite". If you can find the "Earth" and "satellite" 3D pictures, you can also use the "Insert/Picture" submenu under the "From File" command, insert them into the slide.

2. Arrangement of the "satellite" movement pathway

Because "Earth" is fixed in the PPT courseware of the Earth satellite movement, you just have to set up the "satellite" movement path is enough. First select "Satellite", then turn the "Add Effect/action path" submenu in the Custom Animation task pane, select the "More action path" command to open the dialog box, and then select the "Circular extension" command, "yes" to see the "satellite" coiled around the Earth's operation effect.

If the "Earth" and "satellite" trajectory of the location is not suitable for each other, you can select the middle of the two, with the mouse to drag to the appropriate position. Assuming that the "satellite" trajectory of the shape or size is not appropriate, you can use the mouse to select the "satellite" trajectory, and then drag the control points around the track to stop adjusting, thus completing the satellite along the trajectory of the elliptical motion demonstration effect.

3. Arrangement of "satellite" animation effect

Using the mouse to double-click the slide in the "satellite" motion trajectory, turn on the timing option of the Circle Expansion dialog box, select Very slow (5 seconds) in the Speed Drop-down list, and then select "Until next click" in the "Repeat" drop-down list (this allows the satellite to orbit the Earth continuously), or according to the teaching needs to choose the appropriate "speed" and repeated times. Finally switch to the "effect" option, the "Smooth start" and "Smooth finish" two items in front of the hook removed. Then click the Play button in the Custom Animation task pane to see the effect of the "satellite" coiled around the earth movement.
