3 Laws Of Motion
First Law Of Motion - INERTIA
- A still object will stay as is
- A moving object will keep moving with the same speed
- Won’t change unless acted upon by an unbalanced force
- Things want to stay where they are
- Laziness - The object won’t move
Second Law Of Motion - FORCE & ACCELERATION
- Heavy and light has different movements
- Force = Mass x Acceleration
- Law states that the rate of change of momentum of an object is directly proportional to the
- unbalanced force in the direction of force.
- The acceleration of an object is directly proportional to the net force exerted and inversely
- proportional to the object’s mess
Third Law Of Motion - ACTION & REACTION
- When you kick the ball, your leg is the force and the ball is the motion.
- For every action, there is an equal and opposite reaction.
- A force in anything.
- Force is gravity
- Action is when you do something
- Reaction is what happen
Newtons 3 Laws of Motion
First of all, what are the 3 laws of motion? What does this mean? Well, Issac
Newton is a famous scientist who came up with these 3 laws of motion. Which are -
1) Inertia, 2) Force & Acceleration, and 3) Action & Reaction. All of these laws have
different meanings and they all do different things. These are involved in our life a lot,
even when you don’t know it. So...for those who need to know what these laws are,
I’m here to tell you. Lets Go!

First Law of Motion - Inertia
So, what is Inertia? Inertia is when an object stays in its same position. This means
that something is very hard to move and will often stay in its unchanging position.
It will remain still unless acted upon by an external or unbalanced force. Inertia is the
resistance of any sort of physical object to any change in its state of motion. For
example - You won’t be able to push a wall forward, or you won’t be able to pull it
towards you. Unless you use something destructive like a wrecking ball or another
hard machine used for such things like breaking walls or bustings things down.

Second Law of Motion - Force & Acceleration
What is Force & Acceleration? Well, force is any push or pull acted upon an object in
any direction. So, if I push a box left, me pushing it is the force and the box moving is
the motion.
any direction. So, if I push a box left, me pushing it is the force and the box moving is
the motion.
But, acceleration is more complicated then that. Acceleration doesn’t only
have a magnitude, but it also has a direction. This law states that force on an object
equals the mass times the acceleration. Mass x Acceleration = Force. Also heavy and
light objects have different movements.

Third Law of Motion - Action & Reaction
What is Action & Reaction? Newton said, “For every action, there is an equal and
opposite reaction.” Which means that if something is acted upon there will always
be a reaction. Like, if I hit someone, they will react in some way. An Action is when
you do something, like if you kick a ball thats an action. A reaction is when you’re
action makes something react to what you did. Reaction is what happens after you’re
action.

Facts about Issac Newton
Issac Newton was a famous scientist. He worked in many areas of mathematics and
physics. Newton developed the theories of gravitation in 1666, thats when he was
only 23 years old. About 20 years later, he created his 3 laws of Motion. In 1687, he
published, ‘Philosophae Naturalis Prinicipia Mathematica’ This was regarded to be
the one of the important books in the history of science. In it he describes universal
gravitation and the 3 laws of motion.
