types of forces

DEFINE
attraction or repulsion that arises between electrically charged particles because of their motion.

Examples of magnetic force is a compass

unit of H is amperes per metre

advantages
Magnetic forces can be used to aid humans through technology

Disadvantages : Magnetism starts to decrease (and can be permanently lost) at 80°C*

uses
Magnetic fields can be used to make electricity

facts
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.

DEFINE
Nuclear forces are the forces that act between two or more nucleons.

example
is the binding of protons

units of nuclear force 10,000 N

Pros of nuclear energy Cons of nuclear energy
Carbon-free electricity Uranium is technically non-renewable
Small land footprint Very high upfront costs

uses
The nuclear force has an essential role in storing energy that is used in nuclear power and nuclear weapons

facts
The strong nuclear force is one of four fundamental forces in nature. The strong force is 'felt' between nucleons (protons and neutrons)

DEFINE
gravitation is the force that pulls two masses toward each other.

EXAMPLE
it is the force that holds suns harmfull gasses

UNITS
newton

ADVANTAGE
it allows earth to retain its gravity
DISADVANTAGE
earth will end up heating of sun from far away if no gravitational force

USES
it helps in keep all the planets to stay in their own orbit

define
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

examples
rubbing your hands

units
the unit of friction is newton

ADVANTAGE
it helps to support ledder against the wall
DISADVANTAGE
Heat is generated at this surface of contact due to the opposing force of friction.

uses
it is used in car brakes

FACTS
it can generate static electricity

DEFINE
the repulsive interaction between two charged bodies

EXAMPLE
The shock that is felt after touching a doorknob.

UNITS
It is measured in newton

Advantages
Very high collection efficiencies, even for very small particles
DISADVANTAGE
Cannot control gaseous emissions

USES
thr charge in electrical bulb

facts
Objects with the same charge, both positive and both negative, will repel each other, and objects with opposite charges, one positive and one negative, will attract each other
