# What is a function of time?

Originally Answered: What does as a function of time means? A is a Function (mathematics) of B means that for every value of B there is a single, well-defined corresponding value of A. That’s it. So X is a function of time means that for every instant of time, there’s a single well-defined value of X.

## What is a function of time in physics?

Anything that changes predictably over time, and can be represented by a mathematical equation, can be called a function of time. A moving object changes position over time. If it changes in a mathematically predictable way then the position can be said to be a function of time.

## What does velocity as a function of time mean?

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object’s speed and direction of motion (e.g. 60 km/h to the north).

## What does position as a function of time mean?

How do we find out how the position of a object varies with time, when it is moving under the influence of constant acceleration? So if you know the initial position, the initial velocity, and the acceleration, then you can determine the position of the object as a function of time. …

## Is everything a function of time?

Also, time does not necessarily matter, while it can be useful in determining the future, it doesn’t necessarily connect to everything. Any event can be placed in a certain time but decisions, pseudo-random events, and many different things could be done without time having any affect.

## Who invented time?

The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.

## What is the acceleration as a function of time?

Acceleration is defined as the rate of change of an object’s velocity. Just like the derivative of the position function gives you the velocity as a function of time, the derivative of the velocity function (which is also the second derivative of the position function) gives you the acceleration as a function of time.

## How do you find velocity as a function of time?

Calculating instantaneous velocity Given an equation that models an object’s position over time, s ( t ) s(t) s(t), we can take its derivative to get velocity, s ′ ( t ) = v ( t ) s'(t)=v(t) s′​(t)=v(t). We can then plug in a specific value for time to calculate instantaneous velocity.

## Is distance a function of time?

The indefinite integral is commonly applied in problems involving distance, velocity, and acceleration, each of which is a function of time.

## How do you find the current function of time?

The current as a function of time can be found by taking the time derivative of the charge: I(t)=−QRCe−t/τ. The negative sign shows that the current flows in the opposite direction of the current found when the capacitor is charging.

## What is height as a function of time?

Projectile Motion. An object is thrown straight up from the top of a building h feet tall with an initial velocity of v feet per second. The height of the object as a function of time can be modeled by the function h(t) = –16t2 + vt + h, where h(t) is the height of the object (in feet) t seconds after it is thrown.

## What is a function of position?

The position function (also called a position equation) tells you where an object is at a certain point in time. For example, the following graph of a position function tells you (in meters) where a car will be in the first few seconds after its start: Position function of a car.

## What does it mean as a function of?

1 : something (such as a quality or measurement) that is related to and changes with (something else) Height is a function of age in children. It increases as their age increases. 2 : something that results from (something else) His personal problems are a function of his drinking.

## Is time a human concept?

Inevitably, some have concluded that time is simply a human construct. … The theory, which is backed up by Albert Einstein’s theory of relativity, states space and time are part of a four-dimensional structure where everything thing that has happened has its own coordinates in spacetime.

## What is the concept of time?

Summary: The concept of time is self-evident. An hour consists of a certain number of minutes, a day of hours and a year of days. … Time is represented through change, such as the circular motion of the moon around Earth. The passing of time is indeed closely connected to the concept of space.

## Does time actually flow?

Every moment that passes finds us traveling from the past to the present and into the future, with time always flowing in the same direction. At no point does it ever appear to either stand still or reverse; the “arrow of time” always points forwards for us.

## What causes time?

1. Time is the presence of motion and forces and it is caused by the expansion of space. The perception of time is an emergent phenomenon that is why it is perceived in so many different ways. … This is time dependent potential energy and it includes motion and forces at the atomic level.

## Who invented math?

The earliest evidence of written mathematics dates back to the ancient Sumerians, who built the earliest civilization in Mesopotamia. They developed a complex system of metrology from 3000 BC.

## Who invented homework?

Roberto Nevelis of Venice, Italy, is often credited with having invented homework in 1095—or 1905, depending on your sources.
