Forces and Changes in Motion

electric, magnetic, and gravitational are what type of force? And what does net zero mean?

Thanks!

atta	Best Answer The electric, magnetic, and gravitational forces are called action at a distant force(s) that are directly proportional to the line of motion or instantaneous rate of change. When more than one force acts in the direction of the change in motion, that is said to be a net force or SIGMA Fi = m * ai. With that in mind, the netforce is the summation of forces acting upon a body in the directiion of the acceleration that the forces produce. According to Newton's laws of motion, when the summation of forces act upon a body with similar magnitude but opposing direction, the difference of the netforces are said to produce a net-zero impact of acceleration thus, yielding Newton's third law of motion as formally stated: For every force (action), there is an equal and opposite force (reaction) that is equal in magnitude but opposite in direction. In that case, a net-zero is protuded by the difference of the net-forces acting upon a body. This type of law disregards acceleration, which alternately disregards Newton's 2nd law. Therefore, Isaac Newton's 1st and 2nd law corroborates this idea of net-zero. J.C Posted 250 day ago ( 0 ) ( 0 ) Report Abuse

Net 0 means that the sum of the forces (electric, magnetic, gravitational, or other on a body or particle is 0. The body or particle is said to be in equalibrium. If I hang a 10KG weight from a rope, and the weight is doesn't move, then gravity acts downward on the weight awith a force equal to the mass (10Kg) x the gravitational constant (9.8). The rope acts with a force upwards of the same amount, hece the weight doesn't move assuming no other forces from any direction.

electric force is a force that exists between either positive or negative charged particles. Like charges repel and non like charges attract. Charges are usually measured in coulombs (or milli or micro coulombs). Picture a positive charge at a place. the force it exerts on another charge is along the straight ine connecting them. The force is proportional to the charges and and is inversly proportional to the square of the distance between them.
Google Coulombs law.

Magnetic force is a force that acts on electrons. For instance when you move a wire near a magnet, you will induce a current in the wire. Spacecraft can use the magnetic field of the earth to control satellite motion.

Gravitational force is the force of attraction between 2 bodies. It is proportional to the product of the masses and inversly proportional to the square of the distance between them. Google "Newtons law of gravitation"

I think they are weak forces but I wouldn't bet the farm on it.

ELECTROMAGNETIC FORCE

From Wikipedia, the free encyclopedia

NET ZERO ENERGY is a general term applied to a building with zero net energy consumption and zero carbon emissions annually. Zero energy buildings are autonomous from the energy grid supply - energy is produced on-site. This design principle is gaining considerable interest as renewable energy is a means to cut greenhouse gas emissions. Buildings use 40% of the total energy in the US and European Union.[1][2]
