The rate of acceleration of the universe is determined by the cosmological constant, also known as dark energy. This acceleration is causing the universe to expand at an accelerating rate, leading to an increase in the distance between galaxies over time. The exact value of this acceleration is currently estimated to be around 73 kilometers per second per megaparsec.

What did Edwin hubble discover about objects in the universe?
That they are all moving away from each other at a great rate of speed and that speed seems to be acceleration.
What is the rate of acceleration of an object on the moon?
-- The rate of acceleration of an object on the moon is(the net force on the object)/(the object's mass) .-- If the object is falling, with nothing but the force of gravity acting on it, thenits acceleration is 1.623 m/s2 (compared to 9.807 on Earth).
If the hubble constant H is larger at great distances then what is happening?
An increasing Hubble constant at great distances indicates an accelerated expansion of the universe. This phenomenon is attributed to dark energy, a mysterious force causing the universe to expand at an increasing rate. It suggests that as the universe expands, the distance between galaxies grows larger, leading to a greater Hubble constant at greater distances.
Why when a planet is orbiting the sun is it acceleration but the speed does not change?
When a planet orbits the Sun, it experiences centripetal acceleration, which is directed towards the center of the orbit. This acceleration continuously changes the direction of the planet's velocity but not its speed. The speed remains constant because the gravitational force between the planet and the Sun provides the necessary centripetal force to keep the planet in orbit.
How does the age of the universe relate to the hubble constant?
The age of the universe is inversely proportional to the Hubble constant. A smaller Hubble constant would imply a younger universe, while a larger Hubble constant would suggest an older universe. This relationship is based on the assumption that the expansion rate of the universe has been constant over time.
The fate of the universe depends on 2 things what are they?
1.the shape of the universe 2.the rate of acceleration or de-acceleration
If the universe was expanding with 0 acceleration what would the age of the universe be?
The universe simply cant expand at 0 acceleration.
Can a body have acceleration while at rest?
No, a body cannot have acceleration while at rest. Acceleration is the rate of change of velocity with respect to time, so for a body to have acceleration, it must be in motion.
What did Edwin hubble discover about objects in the universe?
That they are all moving away from each other at a great rate of speed and that speed seems to be acceleration.
What does the slope of an acceleration time graph indicate?
The slope of an acceleration-time graph represents the rate of change of acceleration over time. A steeper slope indicates a faster rate of acceleration, while a less steep slope indicates a slower rate of acceleration.
What is the rate at which an object velocity changes?
Acceleration
What is the rate change in velocity?
The rate of change in velocity is known as acceleration.
What is the rate at which speed or direction changes?
Acceleration
How is veolcity and acceleration related?
Velocity is the rate of progress, acceleration is the rate of change of velocity.Hope this helps.
Can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
Which of these is the rate of change in velocity momentum speed friction or acceleration?
The rate of change in velocity is called acceleration.
The rate of change of velocity is called Acceleration What is rate of change of Acceleration called?
Jerk is the term. No, really, it is.
