Newton's Laws of Motion

Newton's First Law

Newton's First Law was actually formulated by Galileo many years previous. It is called the Law of Inertia and states:

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Another way of stating this law in more detail is:

If an object is motionless, it will stay motionless unless acted upon by some force.

If an object is moving at a constant speed or velocity, it will continue at that speed unless acted upon by some force along the line of motion.

If an object is moving, it will move in a straight line unless acted upon at an angle by some force.

The Law of Inertia assumes there is no friction or other resistive force that can slow down an object. Inertia can be best demonstrated in outer space.


Newton's Second Law

The second law is sometimes called the Law of Acceleration, because it concerns forces and what causes objects to move. It can be stated as:

The acceleration of an object of constant mass is proportional to the force acting upon it.

Acceleration is the changing of the velocity of the object. Usually, we are talking about the object speeding up. The word "deceleration" is usually used when the object is slowing down, but that also is acceleration or changing of the velocity.

A force is a push or pull on the object. It may pushing in direct contact or pulling at a distance in the case of gravity.

This law determines the relationship between force, mass and acceleration, which is

F = ma

where:
F is the applied force
m is the constant mass
a is the resulting acceleration
ma is m times a
Note that the force F and acceleration a are in the same direction. Since they have a direction, they are called vectors.

What this law says is that while you are applying a force on an object, it will continue to accelerate or change its velocity. It also states that the greater the force on an object, the greater the acceleration.

Newton's Third Law

Newton's Third Law is sometimes called the Law of Reciprocal Actions or the Action-Reaction Law:

Whenever one body exerts force upon a second body, the second body exerts an equal and opposite force upon the first body.

This is often stated as: "For every action there is an equal and opposite reaction."

Famous Philippine Scientists and their discoveries

Angel Alcala

Arturo Alcaraz

Who are behind all these Things?

The third Science module features some famous foreign scientist and their contributions together with our very own scientist. This also features the qualities that made these scientist what they are now

.

Like other countries, the Philippines can be proud of many men and women who contributed a lot in the field of science. It was a Filipino who invented the fluorescent bulb which is being used in all parts of the world It was a Filipino who designed the light vehicle that was used in exploring the surface of the moon for the first time. It was also a Filipino who developed the embryo culture technique for propagating coconut trees that make all macapuno nuts

Safety First

My Mom and My Dad work in laboratories. My Mom or My Dad is doing Experiment in the Laboratory. I hope my Mom and Dad are ok.

I Put this List Called Safety Rules In The Use of The Laboratory from Science Module 2 so my Mom and Dad will know these Rules and they can be Safe at work:

Safety Rules in the Use Of The Laboratory:

Eye and face Safety:
1. Always wear safety goggles
2. Always point a bottle or test tube away from you and others when it is being heated.

Glassware Safety:
1. Never use broken glassware
2. When heating any glassware, be sure that its thoroughly dry.
3. In picking up hot glassware, always use heat-resistant gloves.
4. Always clean glassware thoroughly after using it.

Sharp Instrument Safety:
1. Always handle any sharp instrument with extreme care.
2. Always cut materials away from you.
3. Avoid using double-edges razors
4. Inform your facilitator immediately if you are wounded.

Electrical Safety:
1. Never touch electrical outlet or appliance when your hands are wet.
2. Do not overload the socket by plugging too many different appliances
3. Do not use long extension cords to plug in an electrical device.

Chemical Safety:
1. Do not mix chemicals unless told to do so.
2. Do not taste or touch chemicals unless instructed.
3. Do not smell any chemicals directly from its container.
4. Close all lid when chemicals are not use.
5 Always rinse chemicals off your skin and laboratory gown with water.

Heat or Fire Safety:

1. Wear safety goggles whenever you use any source of fire.
2. Never heat any chemicals unless told to do so.
3. Never reach across the flame.
4. Open the container when you heat anything
5. Use clamps, tongs, or any heat-resistant gloves when handling hot objects.

Welcome to my blog! I study at Letran's HSP (Home Study Program).
I take the test twice a week and study at home for the rest of the week.

My Favorite Modules are: Science, TLE (Technology and Livelihood Education) and
Health

The hardest Modules are History and Math.

My first test I took was Science Module 1.

In Science Module 1 It was so difficult to memorize the science branches.
I read module 1 and I memorized the branches and took the test.

I wrote all the branches of sciences.

After that I studied for History Module 1 and had to take it a second time because I think I failed it the first time.

History Module 1 was so difficult until I found this Video in YouTube.

This Video tells us Why do we need to Study History...



Follow my blog everyday and you will get to know me better and about Letran's HSP.
