The two elements of graphic translation are and Completion

Direction and distance!

Mathematical problems on Translation
The movement of the following objects in life can be seen as translation ()
A swinging pendulum
A car driving on a straight road
Flags waving in the wind
4. Swinging rope
5 the movement of wiper on car glass
A ball that falls freely from the top of a building
I feel like six
What do you think?

No. It's a circular motion
2. Yes. The car moves in a straight line with the same direction
3. No. the flag should be shaking
4. No. the opening direction of the rope is changing all the time
5. No. the wiper moves around the joint in a circle
6. The uniformly accelerated linear motion in the vertical direction is translation
Personal feelings choose 2 and 6

A mathematical problem about translation
A beautiful free kick on the football field is not a good situation____ Translation. (fill in "yes" or "no")

No, for this example, the orbit required for translation is completely parallel to the ground
That is to say, the track of the ball shooting should be parallel to the ground, but in this process, the ball flies into the goal along a curve, so it is not translational~
