Newton's Laws of Motion
First Law : A body at rest or in uniform motion will
remain at rest or in uniform motion unless some external
force is applied to it
Second Law of Motion : When
a body is acted upon by a constant force, its resulting
acceleration is proportional to the force and inversely
proportional to the mass,
where,
a=acceleration, m/s2
F=force, N
M=mass of a body, kg
Third Law of Motion : It states that to every
action force there is an equal and opposite reaction
force.
Motion :
Displacement
Velocity
Acceleration
where,
S=distance covered by a
moving body in time t, m
V=Velocity of a moving
body, m/s
A =acceleration of a
moving body, m/s2
V0= initial
velocity of a moving body, m/s
T=time of movement, s

Newton’s Law of Gravitation:
Any
two bodies attract each other with a force that is
proportional to the product of their masses and inversely
proportional to the square of the distance between them
where,
F=force of attraction, N
m1=mass of body one, kg
m2=mass of body second, kg
d=distance between two bodies, m
G=Newtonian constant of gravitation
