In high school terms we can show that time is a scalar quantity by looking at the 2 types of quantities we use in physics, scalar and vector. Scalars have just a quantity whilst vectors have both a quantity and a direction. Since time only moves in one direction (from past to future) it isn't necessary to use a vector to describe it since the direction is always the same. All we need to know is how much time we are talking about, not which way it is going.

I'm not sure that this can be "proved" in a scientifically rigorous way even within Newtonian mechanics and in General Relativity it becomes the 4th dimensional in a 4D vector along with the 3 standard Cartesian spatial dimensions.

How can you prove that the earth rotates on its axis?

One way to prove that the Earth rotates on its axis is through the Coriolis effect, which causes moving objects to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This effect is observed in phenomena such as the rotation of hurricanes and the direction of ocean currents. Additionally, the Foucault pendulum demonstrates the Earth's rotation by gradually changing its orientation as it swings back and forth.


What does a sundial prove?

A sundial proves the passage of time by using the position of the sun's shadow to indicate the time of day. It relies on the Earth's rotation to create this movement, making it a simple yet effective timekeeping device.

What property controls the quantity of atmosphere in planets?

The property that controls the quantity of atmosphere in planets is the planet's gravity. A planet's gravitational force is responsible for holding its atmosphere in place. The stronger the gravity, the more atmosphere a planet can retain. Conversely, lower gravity can result in a thinner or less substantial atmosphere.


What is astronomers have been unable to prove that it exists?

There are several speculative ideas in astronomy, which can't currently be proved - nor completely disproved. Some of these include wormholes; parallel universes; the possibility of time travel and faster-than-light travel.

yes


Why time is a scalar quantity?

Time is considered a scalar quantity because it does not have a direction associated with it. Scalar quantities only have magnitude, like a point on a number line. In contrast, vector quantities have both magnitude and direction.
