Terminologies

A

Asteroids

They are the outer space materials.

C

Curie temperature

The temperature at which the ferromagnetic or ferrimagnetic material loses its strong magnetic properties and its phase is change to paramagnetic phase is called Curie temperature.

D

Diamagnetism

The weak and negative response of a material to an external magnetic field is termed as diamagnetism.

E

Electromagnetism

It is the branch of physics that studies the relationship between electricity and magnetism.

F

Ferromagnetic

A ferromagnetic materials is one that can become a strong permanent magnet.

Friction

The resistance force that one surface or object encounters when moving over another.

M

Magnetism

It is the property of materials to attract or repel each other because of the motion and alignment of electrons.

P

Paramagnetism

It is the weak, positive magnetization of a material in response to an applied magnetic field, due to the presence of unpaired electrons.

U

Uniform motion

A straight-line motion at constant speed. Even at constant speed, turning needs a centripetal force, hence only a straight-line motion.
