Any skydiver can fall at a constant velocity. This is called the, "Terminal velocity".
Since we do not have the picture that you mention, nothing more can be assumed.
You can search for images of constant velocity joints on the internet using a search engine or visit automotive parts websites for detailed pictures and diagrams. Additionally, you can check automotive repair manuals or guides for illustrations of constant velocity joints.
Is there a picture of a man falling off Hoover Dam during construction and he is waving?
To draw a picture for velocity, first you need to understand what velocity means. Velocity simply means speed in a given direction. So for a picture you simply need to draw something related to something having speed. For example a ball has speed so you could draw a ball.
While your speed may be the same, your direction is constantly changing. So there is an angular acceleration. The force caused by this is called centripetal force, and it points towards the center of the circle. You can know this by feeling it, or by drawing a picture of the force system. Acceleration is broken up into normal and tangential components for rotation. The tangential is zero because you are moving at a constant speed, however the normal is not zero, and points to the center of the circle by definition.
I would guess that the picture was not properly secured if a picture fell off the wall.
Yes, it is possible to do this.
This is not possible. There is no such thing as Tortimer's Picture.
The force that holds a picture on a wall is the force of friction between the back of the picture frame and the wall. This friction prevents the picture from sliding or falling off the wall.
Sorry but it is not possible to put a picture in an answer in wikianswers.
It is not possible to change your profile picture to a video.
Yes, it is possible for someone to unblur a picture using various image editing techniques and software tools.
The picture is resting on the shelf, which counteracts the force of gravity pulling it down. The shelf provides support that balances the weight of the picture, preventing it from falling.
