About Physics class 11 Notes
You will learn lot of new thinks in Physics class 11 like about electricity Flow of current in
metals is due to free electrons. In absence of any externally applied emf (by means of a
battery) the free electrons move randomly through the metal from one point to another
giving zero net current.
When connected to a battery, the free electrons get accelerated due to the electric field (set
up by the battery) and they gain velocity and energy. However, the passage is not smooth and
the electrons collide with the lattice ions in which the ultimate gainer (of energy) is the ion.
As we know the temperature of a body is related with the energy of vibrations of these ions,
these collisions results in increase in temperature of the metal. The loss of energy of electrons
in collision and their acceleration by the electric field, finally, results in drifting of electrons in
a particular direction. (Although the actual motion of electrons is erratic, the overall effect is
of drifting of electrons). Apart from this mechanic is most important part of class 11 physics
on which you will learn Motion means change of position with time. When a body is at rest,
its position does not change with time. But how do we describe the position of a body? In
order to do that we need to describe it relative to another body for reference.
Thus, rest and motion are relative. A man sitting in a car moving at 55 kmph on highway is at
rest relative to a co-passenger, while he is in motion relative to a person standing on the
highway.
In order to describe rest and motion, we select a frame of reference and then describe rest
or motion relative to this frame of reference.
Motion can be of two types - transnational & rotational.

When a body moves such that it always remains parallel to itself throughout the motion it
undergoes translation. When a body moves so that each point in the body maintains a
constant distance relative to a fixed axis in space, the motion is rotation.
