# Question: Can An Object Move Forever?

## How fast can an object move in space?

about 16,150mphOut into space Once at a steady cruising speed of about 16,150mph (26,000kph) in orbit, astronauts no more feel their speed than do passengers on a commercial airplane..

## Can an object move without force?

Yes, it is possible to have motion without a force being present. Newton’s first law states that, in fact, an object must continue to move at the same…

## What force causes objects to float in water?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. The upwards push of the water increases with the volume of the object that is under water; it is not affected by the depth of the water or the amount of water.

## Can you be still in space?

On the other hand, an object can be standstill in a reference to another object, despite of the fact if both are in motion, orbiting a larger objects or simply flying free. So, the answer is YES always when it is in reference to another space body. Otherwise, there is no such thing as stand still in space.

## What does space smell like?

sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts.

## Is space in a vacuum?

Outer space has very low density and pressure, and is the closest physical approximation of a perfect vacuum. But no vacuum is truly perfect, not even in interstellar space, where there are still a few hydrogen atoms per cubic meter.

## What happens to a moving object?

If something is moving, it will carry on moving at the same speed and in the same direction until a force happens to change it. LAW 2 – Forces make things speed up (or accelerate). … the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.

## What causes objects to move and stay still?

A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest. … Not all forces cause motion, however. Some forces, like gravity and friction, resist or work against movement.

## What happens if you throw a ball in space?

If you are throwing the ball at ‘space’ space, I.e, outer space, then it will suffer infenitisemally small resistive force. Since no force is experienced, it would continue in the velocity with which it left your hand(Newton’s first law). … Gravitational acceleration stops when the ball hits that surface.

## What would happen when an object start moving if there is no friction?

In a world without friction, the object would continue to slide forever, if not acted on by another force. … It states that an object at rest will stay at rest unless acted on by another force, and an object in motion will stay in motion unless acted on by another force.

## Do objects move forever in space?

In the same way, a spacecraft far from any source of gravity would need no thrust to keep it moving at a constant speed in a given direction. Once set in motion, it will keep moving forever without propulsion, since there is no friction in space to slow it down.

## Can an object stop in space?

Space ships do not stop when they run out of fuel. While outer space does contain gas, dust, light, fields, and microscopic particles, they are in too low of a concentration to have much effect on spaceships. As a result, there is essentially zero friction in space to slow down moving objects.

## Can you accelerate forever in space?

You can accelerate forever, and because of relativity, you will never reach c, so you will in fact have infinite acceleration. In the real universe, this is not possible, because the mass of the universe is finite.

## Can an astronaut throw a ball back to Earth?

Can an astronaut throw a ball to the Earth? The answer is Yes, and No. … The extra velocity you gave it with your throw is in the same direction as before, but because of the orbit, that direction now points away from the Earth and directly back towards the ISS. So it doesn’t keep going towards the Earth.

## Can you throw something off the moon?

No. The moon’s escape velocity is 2,300 m/s (Moon Fact Sheet ). The fastest thrown ball is just over 47 m/s, by Aroldis Chapman in baseball. … You can throw a ball out of the gravity of most of the moons in the solar system.
