Terminologies
A
The rate of change of velocity of a moving object is called as acceleration. Its unit is \(m/s^2\).
The simultaneously acting force with the reaction force. Its not the cause.
The depth at which an object appears due to refraction.
C
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
The change in the direction of light due to refraction.
The weak and negative response of a material to an external magnetic field is termed as diamagnetism.
Splitting of white light into its different colors due to refraction.
E
It is the branch of physics that studies the relationship between electricity and magnetism.
F
A ferromagnetic materials is one that can become a strong permanent magnet.
The resistance force that one surface or object encounters when moving over another.
I
An inertial frame is a reference frame that is not accelerating or rotating, where objects move with constant velocity unless acted on by a net external force.
The third law is applied only when two objects interact with each other.
M
It is the property of materials to attract or repel each other because of the motion and alignment of electrons.
Momentum is the “quantity of motion” of an object–the product of its mass and velocity, \(\vec p=m{\vec v}\). It’s vector and takes the direction of velocity.
P
It is the weak, positive magnetization of a material in response to an applied magnetic field, due to the presence of unpaired electrons.
R
The force which is always equal and opposite of action force, without any time delay.
T
Complete reflection of light when the angle of incidence exceeds the critical angle.
U
A straight-line motion at constant speed. Even at constant speed, turning needs a centripetal force, hence only a straight-line motion.
