How do you measure the true velocity of an object in the universe if the velocity of all objects in the universe are relative to each other?
If anyone ever referred to the "true" velocity of an object, he mis-spoke.
All we can directly measure from the earth is an object's velocity relative to the
earth. And when we have measured the velocities of several objects relative to
the earth, then we can calculate the velocity of one relative to any of the others.
But it's quite correct to observe that there's no such thing as the "true" or "real"
velocity of anything, without reference to something else.
Except for electromagnetic radiation, including light. That speed is always the same
for all observers, no matter who you are, or how you're moving relative to anything
else.
If I'm moving north at 0.3c, and you're moving south at 0.5c, and Mr. Tompkins
is moving west at 0.9c ... all relative to Dallas Texas ... and somebody in Seattle
shines spotlights at all three of us, then each of us measures the light passing
him at the same speed . . . 'c'. Each of us measures the same number.
Makes no sense at all. But it's true.
What else can I help you with?
What are three properties of components of the universe that can be determined using electromagnetic radiation?
Three properties of components of the universe that can be determined using electromagnetic radiation are temperature, chemical composition, and velocity. The temperature of celestial objects can be inferred from the peak wavelength of their emitted radiation, as described by Wien's Law. The chemical composition is revealed through spectral lines, which indicate the presence of specific elements. Additionally, the Doppler effect allows astronomers to measure the velocity of objects by observing shifts in the wavelength of their emitted light.
Why the redshift important?
Redshift is crucial in astrophysics as it provides evidence for the expanding universe, allowing astronomers to measure the velocity at which galaxies are moving away from us. This phenomenon helps in determining the universe's age and supports the Big Bang theory. Additionally, redshift assists in understanding the composition and structure of distant celestial objects, contributing to our knowledge of cosmic evolution.
IS velocity possible in zero gravity?
Velocity is relative to the observer and or objects that are in the area , if your sitting in true zero gravity from your point of view you will be standing still but in-reality your velocity will based on your original thrust. Some one watching you (at a zero velocity) from another location might see you zoom by at the original velocity. So the new question is if that other person has zero velocity and is in zero gravity what time will it be when they look at their watch ? Hmmm
What is the equation for velocity approaching that the speed of light?
The equation for velocity approaching the speed of light is given by the relativistic velocity addition formula: v = (u + v') / (1 + u*v'/c^2), where v is the relative velocity between two objects, u is the velocity of the first object, v' is the velocity of the second object, and c is the speed of light in a vacuum.
What is an instoment used to measure the stars?
An instrument used to measure stars is called a spectrometer. It analyzes the light emitted or absorbed by stars, allowing astronomers to determine their composition, temperature, distance, and velocity. Another important tool is the telescope, which magnifies distant celestial objects, enabling precise observations and measurements of stars’ positions and brightness. Together, these instruments enhance our understanding of the universe.
How can one determine the relative velocity between two objects?
To determine the relative velocity between two objects, you can subtract the velocity of one object from the velocity of the other object. This will give you the relative velocity between the two objects.
How do you measure an objects speed and direction?
Velocity
Why is relative velocity AFTER equal to Vf2 minus Vf1 but relative velocity BEFORE equal to V1 minus V2 in the coefficient of restitution formula?
relative velocity is defined as the time rate of change of one object with respect to another object.the relative velocity depends upon the observer i.e.if the velocities of two objects are same then the relative velocity also seems to be equal.
What is the combining of velocities known as?
The combining of velocities is known as velocity addition or relative velocity. It involves adding or subtracting the velocities of two objects moving relative to each other.
What happens when you move magnets?
Their position relative to other objects in the universe changes.
What is the definition of absolute velocity?
Absolute velocity is the velocity of an object with respect to a fixed point in space, regardless of the motion of other objects. It provides a consistent measure of an object's speed and direction in relation to a stationary frame of reference.
The measure of an objects speed and direction is the objects?
The measure of an object's speed and direction is the object's velocity. Velocity is a vector quantity that includes both the speed (magnitude) and the direction of motion of an object.
Velocity is a measure of an objects what two things?
Velocity is a measure of an object's speed and direction of motion. It describes how fast an object is moving and in which direction it is moving.
Is a measure of an objects velocity the same as the measure of the objects inertia?
No.Consider a grain of rice and a banana. If you threw these at someone so that they were moving at the same speed, their velocities would be the same.However, you would hardly feel the impact of the grain of rice but the banana would hurt.The force of the impact is a measure of the relative inertia of the two objects.Where two objects are traveling at the samevelocity, the inertia is greater in that object that has the greatest mass.
Velocity addition is used when motion involves?
Velocity addition is used when dealing with two objects moving at different velocities relative to each other. It helps calculate the combined velocity of the objects when seen from a different reference frame.
How does frame of reference measure motion?
A frame of reference provides a perspective from which to observe and measure motion. By establishing a fixed point or system of coordinates, it allows for the comparison of an object's position and velocity relative to that frame. This helps to quantify and analyze the movement of objects in a specific context.
What do motionless objects have in common with objects that are moving in a straight line with speed?
Motionless objects and objects moving in a straight line with constant speed both have a constant velocity of zero or a constant velocity in a single direction, respectively. They share the characteristic of having a consistent position relative to a reference point over time.
