-Action/ Reaction

2.  The law of Motion is formulated by Sir Isaac Newton
thus got the name of Newton’s Law of Motion. There are
physical three laws which are considered the basis for
classical mechanics. The law of motions describes the
relationship of force acting on body and the force which
gave of the motion. Newton's laws are applied to
physical objects which are considered or idealized as a
particle, in the sense that the extent of the body is
neglected in the evaluation of its motion. In the given
interpretation mass, acceleration, momentum, and the
most important part “force” are assumed to be externally
defined quantities

4. Newton’s first law of Motion
(Inertia):
An object at rest stays at rest, unless an external,
unbalance force acts on it.
Newton's first law of motion applies to
both objects in motion and objects at
rest. Objects in motion have inertia
because they want to remain in motion.
For example a roller coaster has
inertia. When it starts a drop it wants
to continue moving in the same
direction at a constant speed. It
doesn't however because the tracks act
as an outside force and change the
roller coaster car's direction.

5. -Newton’s first law states that the speed of an object in
uniform in motion will remain constant unless there’s an
external force applied to it.
-An object at rest will remain at rest if there is no
external force applied to it.
-The first law of motion is also
called Law of Inertia

6. (Inertia)
 Newton's first law applies
to object at rest as well.
An object at rest has
inertia because it wants
to stay at rest. The more
mass the object has the
greater the tendency that
it will remain at rest when
another force acts on it.
In the picture the car is in
a state of rest, and until
another force great
enough to move it acts
upon it, it will remain at
rest.

8. Second law of motion
(acceleration)
~Newton's second law of motion pertains to the behavior of
objects for which all existing forces are not balanced.
~The second law states that the acceleration of an object is
dependent upon two variables - the net force acting upon the
object and the mass of the object.

9. What does it mean?
Everyone
unconsciously
knows the second
law. Everyone
knows the
heavier objects
require more
force to move the
same distance as
lighter objects

10. However, the Second Law gives us an exact
relationship between force, mass, and
acceleration. It can be expressed as a
mathematical equation:
F=MA
FORCE= MASS * ACCELERATIONS

12. For every action there is an
equal and opposite re-action.
What does it means?

13. This means that for every force there is a
reaction force that is equal in size, but
opposite in direction. That is to say that
whenever an object pushes another object it
gets pushed back in the opposite direction
equally hard.

14. Let's study how a rocket works to understand
Newton's Third Law.
The rocket's action is to push down on the ground with the force
of its powerful engines, and the reaction is that the ground
pushes the rocket upwards with an equal force.
