__Below are given ____Newton____’s
Laws and we observe that the New Concept does not clash in any way with these
laws, but rather accommodate them.__

**a.
****Newton****’s First Law of Motion**

It states that every body
continues in its state of rest or of uniform motion in a
straight line __(velocity)__, unless it is acted upon by some external
__force__ which compels it to change that state. (ICSE Physics Alternative
Part – II Page 42 Inertia – 77 College Physics)

**b.
****Newton****’s Law of Universal
Gravitation**

It states that the __force__
of attraction between any two objects in the Universe varies directly to the
product of their __masses__ and inversely to the square of the distance
between them i.e.

F a
__m _{1}m_{2}__

d^{2}

**c.
****Inertial and gravitational mass**

F =
m_{1} x a or
m_{1 }= __ F
__ W
= m_{g } x g or m_{g =
} __W __

a g

**d.
****Newton****’s Second Law of Motion**

*It states that the rate of
change of momentum of a body is proportional to the impressed force and
takes place in the direction in which the force acts. (mass x
changing velocity or mass x acceleration)*

Note: The property that a body
possesses due to the combined effect of its mass and __velocity__ is called
__momentum__. p = m x v

**e.
****Newton****’s Third Law of Motion**

It states that to every action
there is an equal and opposite
reaction
* *

__Note:- 3 We observe from above __

**
**a.
deals with “motion in a straight-line” i.e. ** Velocity
**, and

b. deals
with __Force , Mass and Distance __

c.
deals with ** Force, Mass and Acceleration** i.e. F = m x a .
Here acceleration a also becomes g (Gravitational Acceleration).

*d.
*deals with ** Momentum **= mass x velocity and also
Force (all of which have been given above).

*e.
*deals ** mainly with force**. All these have been dealt with
in detail
