About Normal Force
What is normal force?

How many variables does the Inertia has?
2

What is a contact force?
Any force that needs contact to occur
How do objects speed up?
By adding force in the direction the object is moving

deoxyribonucleic acid
What are the Newton Laws?
They are 3 laws that are Inertia, Mass and Acceleration
How do objects slow down?
By applying a force to the contrary direction the object is moving
What is the first Newton's law?
Every object persists in its state of rest or uniform motion is a straight line unless it is compelled to change that state by forces impressed on it

rest/motion
What was the name of the union of all continents millions of years ago?
Pangea
What does Fn means?
It means normal force
How can force affect the acceleration of an object?
The force you use to move an object will be proportional to the acceleration of an object, for example, small force will give you a small acceleration, but a bigger force will give you a bigger acceleration
What is the most important part of the 1st Newton's Law?
Unless a force is applied to it
What is Inertia?
The tendency of an object to resist the change of the original movement
What was Charles Darwin theory about?
the theory of biological evolution by natural selection. Darwin defined evolution as "descent with modification," the idea that species change over time, give rise to new species, and share a common ancestor.
What does the word normal in normal force means?
It means perpendicular
What will happen if a bird is flying with enough force to go 10km per hour, and then a wind wave with the double of force goes to the contrary direction the bird is flying?
The bird will slow down or even go backwards
Does the Earth have some movements like this ones?
Yes, spinning in the axis
What defines Inertia?
It is define by the velocity and force is responsible from its change
