# Object accelerated at one G for one year

• Supersiiix4
In summary, The conversation discusses an object being accelerated at 1G for 1 year and the resulting velocity after that time. It also mentions the concept of fractional velocity of light and how it is calculated by dividing the velocity by the speed of light.

Hello, this is my first post on Physics Forums.

If an object at rest is accelerated at 1G (9.81m/s^2) for 1 year (3.15569 x 10^7 Seconds), using the
equation V= Vo +AT

V=( 9.81 m/s^2) x (3.15569 x 10^7 Seconds) = 10,000,012.1 M/S

What does it mean when it asks for units of fractional velocity of light?

Speed of light= 299 792 458 meters per second

Welcome to the PF.

(it's best to use the correct capitalization on the units, so m/s is meters per second...)

They asking you to divide the velocity by the speed of light "c" to get a fractional number. Like, if your speed is half the speed of light, it can be written 0.5c

## 1. What does it mean to accelerate an object at one G for one year?

Accelerating an object at one G means increasing its velocity by 9.8 meters per second every second. Doing so for one year would result in a significant increase in the object's speed.

## 2. How is one G of acceleration achieved?

One G of acceleration can be achieved through the force of gravity, such as when an object is falling towards the Earth. It can also be achieved through other forces, such as the thrust of a rocket or the pull of a rollercoaster.

## 3. What would happen to an object accelerated at one G for one year?

If an object was able to withstand the forces of acceleration, it would experience a significant increase in speed and would cover a large distance in one year. It would also experience changes in its physical properties, such as increased weight and strain on its structure.

## 4. Is it possible for a human to withstand one G of acceleration for one year?

No, it is not possible for a human to withstand one G of acceleration for one year. The human body is not designed to withstand such high forces for extended periods of time and would likely result in serious injury or death.

## 5. Why would an object be accelerated at one G for one year?

An object may be accelerated at one G for one year in certain scenarios, such as space travel, to reach high speeds and cover large distances in a relatively short amount of time. It may also be used in experiments to study the effects of such forces on objects and materials.
