do objects accelerate in space?

And it maintains constant velocity until some external forces (either moving or stable solid, liquid, gas particles/objects) changes its direction or speed. And it will never accelerate until some external forces accelerate it. ... By practically, the object will slows down by the space junks and other particles.

It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth).

In special relativity, it is impossible to accelerate an object to the speed of light, or for a massive object to move at the speed of light. However, it might be possible for an object to exist which always moves faster than light.

Yes the trick isn't to actually travel faster than light, just use a shorter way. There is a theoretical model of a drive which could warp and bend space to travel faster than light.

If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion.

Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.

If acceleration points in the same direction as the velocity, the object will be speeding up. And if the acceleration points in the opposite direction of the velocity, the object will be slowing down.

Acceleration is the change in speed or velocity of an object over a certain time. It can be calculated by dividing the change in velocity by the total displacement.

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

Microgravity is sometimes called "zero gravity," but this is misleading. Is There Gravity in Space? Gravity causes every object to pull every other object toward it. Some people think that there is no gravity in space. In fact, a small amount of gravity can be found everywhere in space.

A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). This numerical value for the acceleration of a free-falling object is such an important value that it is given a special name.

Near the surface of the Earth, any object falling freely will have an acceleration of about 9.8 metres per second squared (m/s 2). Objects falling through a fluid eventually reach terminal velocity .

Uniform Acceleration Equations One of the common examples of uniformly accelerated motion is freely falling bodies. The only acceleration which is acting on the body is g (acceleration due to gravity).

It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). ... The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

The word acceleration implies a change in the object's velocity. One example of this is vertical particle projection. When an object is thrown upwards, the maximum height velocity of the body is zero, but constant acceleration due to gravity is still working.

Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
