Linear Kinetics and Newtons Law's
Force
Force is some times described as a push or pull
Force is a mechanical interaction between 2 objects
Force involve friction and gravity
Gravity
Gllileo, Kepler and halley started realizing that there was an atractive force between objects
Also force was related to mass that is the amount of material the object and body has
This force cause the elliptical orbit of the planets arround the sun
Astronauts orbit in earths gravity
Gravity is related to weight. when the gravity is lower the weight of an object or body will be lower but if the gravity is higher, the weight of the object and body will be higher
Mass and Weight
Mass is the amount of material in an object or body, usually meassured in kilograms (no weight)
Weight is the effect of force gravity on mass
In the moon all of us have the same mass as in the earth, but as the gravity is lower the weight is also lower (weight depends on Gravity)
Newtons 1st law of motion
"Newtons first law of motion is stated as: : An object will remain at rest or
continue with constant velocity unless acted on by an unbalanced force.” this means that an object or body will stay with a constant velocity unless there is an unbalanced force. This law is known as the law of inertia.
There is always a force balancing the weight, acting in oposite direction, this force comes from the ground and is called reaction force.
Newtons 2nd law of motion
Newtons second law of motion consists in the relation of the change in motion or acceleration and the force causing that change
"It can be stated as: The acceleration (for a body/object of constant mass) is proportional to, and in the same direction as, the unbalanced force applied to it." this is called as the law of acceleration.
This is writen as "force is equal to mass multiplied by acceleration", in other words F = ma.
Body or objects change in motion is related to the size of the force causing the change
Newtons 3rd law of motion
The third law of motion explains the forces between 2 objects
"It can be stated as: “When one body or object applies a force to another, the second body or object will apply a force equal in size but opposite in direction to the frst body or object.” this is called the law of reaction
There are 3 aspects to understand this law, the first one is that the two forces are in different bodies. the second one is that the forces are exactly the same in size and mass. The final one is that both forces happens exactly at the same time.
