Newton's three laws of motion describe the fundamental principles governing the behavior of objects. The first law, also known as the law of inertia, states that an object at rest stays at rest and an object in motion continues in motion at a constant velocity unless acted upon by an unbalanced force.
Example:
When you are
canoeing as you
paddle you are
exerting force onto the
paddle into the water
and that effects the boat
and cause the boat to move.
Example:
When you sit
in a chair you are
exerting force on
the chair and the chair
is exerting force on to
your body.
Newton's 3rd law is
whenever one object
exerts force on a
second object, the
second object exerts an
equal and opposite force
on the first. (for every
action the is an equal
and opposite reaction).
Newton's 2nd Law
Example:
Person A has a
backpack on and
Person B does not.
Both people start at
the same spot and are
running. Person B runs
faster than Person A
because they have less
force pushing on them
and more acceleration.
Example:
If you use the
same force to
push a truck and
push a car, the car
will have more
acceleration that the
truck
Newton's 2nd law is
the acceleration of an
object depends on the
mass of the object and
see the amount of
force applied
Newton's 1st Law
Example:
When you
peddle on a bicycle
the bicycle moves
forward.
Example:
When your standing
on a bus in the aisle
and the bus stops,
but your body continues
to go forward.
Newton's 1st law is an
object at rest remains
in rest and an object in
in motion remains in
motion at a constant
speed and in a straight
line unless acted by an
unbalanced force.
