What creates electromagnetic force?
The electromagnetic force is a force that occurs between electrically charged particles, such as electrons, and is described in electrostatics as being either positive or negative. Objects with opposite charges produces an attractive force between them, while objects with the same charge produce a repulsive force.
What causes the electromagnetic force?
The electromagnetic force is caused by the exchange of photons (effectively ‘particles’ of light) and the chance of photons being emitted or absorbed is related to the charge on an object.
What would happen if there was no electromagnetic force?
Since electromagnetic forces are responsible for regular chemical bonds, every chemical compound would dissolve. All life and all ordinary objects would cease to exist.
Do electrons carry the electromagnetic force?
22.1 Electromagnetism All charged particles, including protons and electrons, interact via the electromagnetic force. This is because most things have charges that cancel each other out, making them neutral, whereas gravity always affects everything with mass.
Is normal force electromagnetic?
The normal force is an everyday force that is felt when a surface pushes against an object that is placed on that surface. The normal force arises from the electromagnetic force; specifically, the electrons in the book push against the electrons in the table.
Where does the normal force act?
Explanation: Normal force always acts perpendicular to the contact surface. It can act counter to gravity or to any other force that pushes an object against a surface. Think of normal force as the force that keeps a surface solid; without normal force, an object would pass right through a surface.
Is FN equal to FG on a slope?
It is important to note that Fy represents what we would measure as weight and Fx represents forces down the slope. Fn is the normal force, Fg is the gravitational force and these are equal and opposite as long as there no vertical motion.
What is Fnet and FN?
-For vertical acceleration (elevators) FN is the apparent weight of. the object and Fnet = Fg + FN. -If Fnet and a are positive (acceleration upward) FN>Fg. -If Fnet and a are negative (acceleration downward) FNFnet and a are 0 (constant speed or rest) FN=Fg.
What does Fnet 0 mean?
Nonzero Net Force
