If the direction from which the light comes changes, then the direction of the shadow changes as well. The shadow basically points away from the light source.

What is a shadow stick?
A shadow stick is a vertical pole placed in the ground. Sunlight casts its shadow on to a level surface below (e.g. a sheet of card or just level ground The length and position of the shadow then depends on both the time of year and the time of day. Local noon can be found from the time when the shadow is shortest. At this time the Sun is highest in the sky and crossing the meridian. However, shadow sticks are not good clocks - the azimuth of the Sun's shadow at a given time changes throughout the year with the Sun's declination. http://www.nmm.ac.uk/server/show/nav.3117
Why does the size and direction of a shadow change?
Because the sun moves through the sky, or at least it appears to do that. Since the sun's position changes with respect to objects on the earth so do their shadows.
Does the size of the shadow of an object depend upon the size of the object?
because its telling you the sun is going nearer so it goes bigger because the sun is very big and the shadow changes because of the height and length of the sun on where it is this is my answer yea and um the flyers rock!
what causes shadow length?
The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.
Why does the length and position of my shadow change as I walk towards a lamppost and away from the lamppost?
Light leaves the lamp and travels in straight lines from its point source. As you move away from the source, the angle between you and the light changes and this the length and position of your shadow changes.

How does the position of the sun in the sky relate to the length of the shadow cast by an object?
The position of the sun relates to the length of the shadow cast by an object because, when the sun is above the object there is no shadow yet, when the sun is say to the east of the object a shadow is cast towards the west, the farther the sun for example east the longer the shadow will be towards the west.
What is the direction of someone's shadow at 10am?
Usually somewhere towards the west. However, the exact length and direction of the shadow depend on your exact geographical position (both latitude and longitude), and on the time of year.
How does a shadow change in the day?
The shadow of a solid object is cast by the Sun on the ground. As the Sun appears to cross the sky between dawn and dusk, so the length of the shadow also changes, both in direction and in length on the ground.Put a wooden post a metre high in open ground on a sunny day. Use a watch, and every hour place a small rock where the end of the post's shadow is on the ground. Eventually, you will see by the position of the rocks, just how the shadow of the post changes during the day.
How can you tell time from shadows?
If you place yourself on the equator at a the time of an equinox, then at mid day your shadow falls directly under your feet because the Sun is directly above you. As the Sun rises to this position and set form it, you shadow will fall to one side of you and the length of this shadow will depend on the height of the Sun in the sky, the shorter it is the higher the sun will be. Thus from the length and position of your shadow you can tell what time it is. Long shadows happen in the morning or evening and short shadows happen towards mid day.
How does the length of your shadow change in the day?
It will Lengthen and shorten during the day, as the angle of the sun changes
At what time is the shadow in front of you?
The shadow is in front of you when the sun is behind you, typically in the late morning or early afternoon. The length and direction of the shadow will vary depending on the position of the sun in the sky.
Why does the length and position of my shadow change as i walk towards a lamp post and when we walk away from the lamp post?
The lower the sun in the sky, the longer the shadow. A shadow is always cast in the opposite direction of incident sunlight. When the sun is directly overhead (at noon) the shadow is shortest.
Why do shadows change as the position of the sun changes?
A shadow is always at the direct opposite side of the light source, so as the light moves the shadow moves.
Does the position of the torch would affect the length of the shadow cast by the pencil?
i think yes as try it yourself
