## How many G’s does an astronaut experience?

Astronauts normally experience a maximum g-force of around 3gs during a rocket launch.

This is equivalent to three times the force of gravity humans are normally exposed to when on Earth but is survivable for the passengers.

Astronauts are trained in high g-force, wear g-suits and must be correctly prepared..

## What is the acceleration of a rocket?

Acceleration = resultant force divided by mass = 4.51 ÷ 0.050 = 90 metres per second squared (90 m/s2). This means that, every second, the speed of the rocket increases by 90 m/s. This is nine times the normal acceleration due to gravity. The same method can be used for a full-sized rocket such as the Space Shuttle.

## Do rockets accelerate in space?

In space, rockets zoom around with no air to push against. … Rockets and engines in space behave according to Isaac Newton’s third law of motion: Every action produces an equal and opposite reaction. When a rocket shoots fuel out one end, this propels the rocket forward — no air is required.

## How fast can a spaceship go?

about 17,500 miles per hourLike any other object in low-Earth orbit, a Space Shuttle must reach speeds of about 17,500 miles per hour (28,000 kilometers per hour) to remain in orbit.

## What happens to the acceleration of a rocket as it burns fuel?

Factors Affecting a Rocket’s Acceleration The faster the rocket burns its fuel, the greater its acceleration. The smaller the rocket’s mass (all other factors being the same), the greater the acceleration.
