Can an object accelerate with no external force?

Acceleration is the change of velocity per unit time, so if there is no force, all we know is that the acceleration is zero. Therefore, the velocity is not changing. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Does an object in space keep accelerating?

It will always accelerate, not because of the throw (the acceleration imparted by the throw ends as soon as it leaves the thrower’s hand), but because of the gravitational attraction of every other object in the universe.

Does an object have to accelerate if forces are acting on it?

According to Newton, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object – changing its speed, its direction, or both its speed and direction.

Can a spaceship accelerate in space?

The astronauts on board the International Space Station are accelerating towards the center of the Earth at 8.7 m/s², but the space station itself also accelerates at that same value of 8.7 m/s², and so there’s no relative acceleration and no force that you experience. This same principle works on extreme scales, too.

Can acceleration is a force?

Acceleration is the rate of change of the speed of an object, so if an object has mass, and it is accelerating through space, then the object is said to exert a force. This principle is described by Newton’s second law of motion.

Is it possible for an object to be accelerating even though it has stopped moving?

Yes, acceleration is a change in velocity, so an object might be momentarily at rest but a split-second later have some speed, i.e. it can be changing its velocity even if it is momentarily at rest.

What is G in space?

Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

What happens to an object thrown in space when force is removed?

Once Force is removed, it can’t accelerate. An object thrown in space will move according to the forces on it in space. For instance, if you threw it in space near the Earth, it would accelerate due to the Earth’s gravity. There can be quite a lot of forces in space: space is a big place.

How does force accelerate an object?

Force is really the only thing that can make an object move (i.e. accelerate). There isn’t a cause of movement (acceleration) other than force, so the plain answer to your question really is this short.

How can an object in space-time travel to Earth?

An object in Space-time will naturally follow the geodesics to Earth. If you stop it with something (i.e. your hand or the surface of the Earth) then the upward force from you gives the illusion of a downward force from the object. There doesn’t have to be any force of acceleration.

Is it possible to move an object without force being applied?

If everything in the world was moved in the same direction, except for your object, you could say that it moved without a force being applied.
