What happens when two objects move away from each other?
If both objects were accelerating away from each-other at half the speed of light, then the distance between them will increase at half the speed of light but the speed of their separation will be the speed of light.
What happens to light from objects when you move towards them?
The wavelength of light emitted by a moving object is shifted. If the object is coming toward you, the light is shifted toward shorter wavelengths, blue shifted . If the object is going away from you, the light is shifted toward longer wavelengths, red shifted .
When objects are moved farther apart from each other the force of gravity?

Weight is described as | the downward force exerted on objects due to gravity |

The law that states that every object maintains constant velocity unless acted on by an unbalanced force is | Newton’s first law of motion |
How does the distance between two objects affect gravity?
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
What happens to light moving away from you?
When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. If an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter.
What happens to light as it moves away from you?
While light is always moving away from its source at the same speed, if your source is moving at a significant fraction of the speed of light relative to whoever’s watching, the wavelength (or color) of the light will change dramatically. Let’s use your example: 50\% of the speed of light.
Can an object move faster than the speed of light?
Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. Unlike objects within space–time, space–time itself can bend, expand or warp at any speed.
Is the speed of light principle violated by 2 photons moving together?
The relative speed of 2 objects is not itself the speed of a ‘thing’, therefore the speed of light principle is not violated by saying that 2 photons moving in opposite directions move away from each other at a relative speed of 2C.
What happens when two objects Bob up and down at different frequencies?
Two Point Source Interference. If two objects bob up and down with the same frequency at two different points, then two sets of concentric circular waves will be produced on the surface of the water. These concentric waves will interfere with each other as they travel across the surface of the water.
What happens when two objects Bob up and down in water?
If an object bobs up and down in the water, a series water waves in the shape of concentric circles will be produced within the water. If two objects bob up and down with the same frequency at two different points, then two sets of concentric circular waves will be produced on the surface of the water.
What happens when two waves interfere with each other?
The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium. Wave interference can be constructive or destructive in nature.
