What causes shadow to change during a day?
the position of the sun
Does the temperature of the atmosphere affect the position of your shadow and why?
Yes, the temperature of the atmosphere can affect the position of your shadow. This is because temperature can cause variations in air density, which can refract light differently and change the apparent position of shadows.
How is position and change related?
Position refers to the location of an object at a specific point in time, while change represents the difference in position over a period of time. Change is the rate at which an object's position is changing or the displacement from one position to another. Therefore, position and change are related in that change is the measure of how position is shifting over time.
Is acceleration the rate of change of the rate of change of position?
no its speed that definds the rate change of position
What causes the moon's shadow to change its placement?
The moon's shadow changes its placement due to the moon's orbit around the Earth and the Earth's rotation on its axis. This movement causes the moon's shadow to shift and change its position relative to the Earth.
What is the purpose of a sundial and how does it work?
A sundial is used to tell time by using the position of the sun in the sky. It works by casting a shadow onto markings that indicate the time based on the position of the shadow relative to those markings. The gnomon (the part that casts the shadow) is oriented towards the North Pole to properly align with the sun's position.
Why does the length and position of my shadow change as I walk towards a lamp post and when I walk away from the lamp post?
The length and position of your shadow change as you walk towards a lamp post because you are moving closer to the light source, which creates a shorter shadow. Conversely, as you walk away from the lamp post, your shadow lengthens and changes position because you are moving further away from the light source, causing the shadow to stretch and shift.
What causes shadows to change position?
Shadows change position because of the movement of the light source, either from the sun, artificial lighting, or other sources. As the angle of the light changes, it creates a different position of the shadows cast by objects. Time of day, season, and location also influence shadow positions.
Can an artificial shadow tells time?
No the only way you can tell time from a shadow is from something ubstruckting direct sunlight any type of light that is not sunlight will not allow the change in earths rotation to change the angle of the shadow.
How can we use shadow to tell the time?
You can use a sundial, which is a device that uses the position of the sun's shadow to tell time. By placing a stick or pointer on the sundial, the shadow it casts can indicate the time based on markings on the sundial's face.
What happens to a shadow when the object is moved?
The shadow's position changes relative to the light source and object. It will move and change in size depending on the direction and distance the object is moved.
