Newton 's Laws of Motion
1. 1 Newton 's First Law of Motion
( moving with constant)
↳ unless it is acted
an object continues in a state of rest or uniform a
velocity upon a net
force
↳
if an object has mass then it has inertia (M mass ,
9 inertia )
↳ inertia is the of
property of a
body that causes it to resist a change in its state rest
or uniform motio
Examples
1 .
Why does the rider continue to move forward after collision ?
↳
during the collision , the barrier exerts a net horizontal force on the bike
bringing it
to rest
↳ this net horizontal rider
force is not exerted on the

according to Newton 's First Law , the rider will continue moving forward with uniform
velocity

Application of Newton 's second law to horizontal 1 vertical motion
↳ a net force is a
single force that has the same effect as the
original forces acting
together
↳
net force is
equal to the vector sum of individual forces ( Fn et Fi tf Fs )
