# Is escape velocity possible?

## Is escape velocity possible?

It can achieve **escape** at any speed, given sufficient propellant to provide new acceleration to the rocket to counter gravity's deceleration and thus maintain its speed. The **escape velocity** from Earth's surface is about 11,186 m/s (6.

## Is escape velocity dependent on mass?

The **escape velocity depends** only on the **mass** and size of the object from which something is trying to **escape**. The **escape velocity** from the Earth is the same for a pebble as it would be for the Space Shuttle.

## Is escape velocity constant?

The formula for **escape velocity** contains a **constant**, G, which is called the "universal gravitational **constant**". Its value is . The unit for **escape velocity** is meters per second (m/s).

## Which planet has lowest escape velocity?

Therefore the smaller the **planet** the less the **escape velocity** will be....
