change the size or shape of the body Main Types Of Forces Gravitational Force An attractive force (gravitational pull) that is only dependent on the masses of the objects. Long range force which acts at a distance Can usually be neglected unless one of these masses is very large Electromagneti...
It seemed that they would do so due to the repulsive electromagnetic force between the positively charged protons located in the nucleus. Physicists later found that the strong force not only holds nuclei together but is also responsible for binding the quarks that make up hadrons. "Strong ...
3.There are no negative gravitational charges (no negative mass) while there are both positive and negative electric charges.This difference combined with previous implies that gravitational forces are always attractive,while electrostatic forces may be either attractive or repulsive. 4.Electric charge ...

Thus, it results in an imbalance of charges between the two materials. When there is an imbalance of charges between the two materials it will mean that the objects will show an attractive or repulsive force. Electron Movement The valence of an atom defines its ability to gain or lose an...
Ampère's force law expresses that there is an attractive or repulsive force between two parallel wires conducting an electric flow. This power is utilized in the formal meaning of the ampere. The definition of SI unit of electric charge, the coulomb, "is the amount of power conveyed in 1 ...

The potential energy contained in the quantum vacuum was all that was required to facilitate the transference (Crane, Manke). Hovering Over a Vacuum Quantum vacuums give rise to the attractive Casimir force, but could we convert this into something that is repulsive instead? Sort of. Research ...
