Yes, artificial gravity can be practically achieved by the use of different forces, particularly the centripetal force and linear acceleration. Artificial gravity is envisaged mainly for space travel. Several methods of generating artificial gravity have been proposed in the past but practical application of artificial gravity for humans in outer space have not yet been built.
The most practical method of producing artificial gravity inside a space station is by using 'centripetal force' to produce a sensation of being pulled towards the "floor" that would be like gravity. In a rotating spaceship, objects inside would be pushed toward the hull. In such a spaceship, the astronauts would walk on the "wall" that they are stuck to, and parallel to what would be the floor of the vehicle. In other words, the wall would become the floor, and the floor would become the wall.
Centripetal space stations have not been built yet mainly due to the large size of the spacecraft that would be needed to allow centripetal acceleration. Size is the main problem. The smaller the spacecraft is, the faster it has to rotate, so if you're going to generate gravity, it's got to be done with a very large spacecraft that spins very slowly like 2 RPM. Another problem would be the total "disorientation" experienced by the astronauts if the space station has windows - like in the ISS. A portion of the spacecraft can be made to rotate, to create artificial gravity - like it has been shown in several sci-fi movies. But if this rotating portion is too small, the astronauts would feel a big difference in the force imposed between their heads and their feet, making them feel dizzy. In any case, the spacecraft has to be huge - like the one shown in 2001-A Space Odyssey - Stanley Kubrick's 1968 masterpiece.
At the moment, there is no such spaceship being built. However, NASA is researching the use of an astronaut-size centrifuge in which the astronaut could spend a certain amount of time in every day. But rotating parts or all of the spaceship requires a lot of energy. Maybe a propulsion system and propellant of some kind or a motor or whatever.
