3 Laws of Motion

3 Laws Of Motion

First Law Of Motion - INERTIA
  1. A still object will stay as is
  2. A moving object will keep moving with the same speed
  3. Won’t change unless acted upon by an unbalanced force
  4. Things want to stay where they are
  5. Laziness - The object won’t move

Second Law Of Motion - FORCE & ACCELERATION
  1. Heavy and light has different movements
  2. Force = Mass x Acceleration
  3. Law states that the rate of change of momentum of an object is directly proportional to the unbalanced force in the direction of force.
  4. 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
  1. When you kick the ball, your leg is the force and the ball is the motion.
  2. For every action, there is an equal and opposite reaction.
  3. A force in anything.
  4. Force is gravity
  5. Action is when you do something
  6. 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.
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.

Fab Fractions

Fabulous Fractions
We are learning to identify the relationship between fractions.

What is 2/4 of 50? 25


What is ½ of 50? 25


What is 4/4 of 8?   This is the same as 1 whole of 8


What is ⅕ of 10? 2


What is 2/10 of 10? 2


What is ⅓ of 12? 4


What is 2/6 of 12? 4


What is 1/13 of 26? 2


What is 2/26 of 26? 2

What do you notice about these fractions?


Show your working for the remainder of the problems

I have 2/16 of a cake at a birthday party. I keep going back for more
and eat another  6/16 of a cake. What fraction of a cake have I eaten
altogether? 2/16 + 6/16 = 8/16


⅓ + ⅔ =      3/3 or 1 whole


⅙ + 2/6 =     3/6 or 1/2


12/25 + 3/25 = 15/25


I have 5/21 of a cake left over from the party. Then I give 3/21 of a cake
to my sisters. What fraction of a cake do I have left over? 5/21 - 3/21 = 2/21

½ + 2/4 =  1 whole


3/6 + ⅔ = 7/6

⅕ + 2/10 = 2/5

Fractions, Decimals & Percentages



WALT: Find fractions of a whole

This is my task/presentation for Wk 6 of Term2. It is completely based around,
fractions, decimals and percentages. There are a few different questions.
I found it easy at the beginning, however, I took a while to do the last question,
about percentages. But, I got through it in the end!

Fractions Finale Presentation



WALT: add and subtract fractions with different denominators.

This is my Fractions Finale Presentation. I also completed one of the provided docs that
i have previously posted.

I want to add ½ with ¼. First I change ½ to  then I add

⅓ + ⅙. ⅓ =   2/6 + ⅙ = 3/6 or ½

¼ + ⅛.  ¼ = 2/8 + ⅛ = ⅜

How can I change ⅔ into sixths ( 4/6)?


How can I change ⅔ into twelfths ( 8/12)


⅓ + ¼ = 7/12

⅓ = 4/12   ¼ = 3/12


⅓ + ⅕ = 8/15

⅓ = 5/15  ⅕ = 3/15

⅙ + ⅛ = 14/48 or 7/24
⅙ = 8/48    ⅛ = 6/48

1/10 + 1/100 = 11/100`

1/10 + 1/1000 = 101/1000


⅓ + 1/7 = 10/21

¼ + ⅕ = 9/20

⅓ + ⅖ = 11/15

List 5 equivalent fractions for:

¼ = 2/8, 3/12, 4/16, 8/32, 5/20

⅓ = 2/6, 4/12, 3/9, 5/15, 6/18

⅕ = 2/10, 4/20, 3/15, 5/25, 6/30

⅙ = 2/12, 3/18, 4/24, 5/30, 6/36
