Below are downloadable examples and explanations of uniform circular motion:

To understand these problems, all we need to do is reapply what we already know about Newton’s Laws, Vectors, Rotational Motion, Kinematics, it is simple. For example gravity is always acting on objects, so take into account gravity, Newton’s laws of an object in motion will stay in motion, enables us to say that the component of the velocity vector in the x-direction will remain unchanged if air resistance is not taken into account. The simple rules to follow are much like that of force:

1) Draw out the problem.

2) Draw it out as a diagram of forces.

3) List all known variables.

4) Solve for what you are trying to find using variables, and using vector rules.

5) Plug in the information you have and solve for unknown variables.

6) Check using logic (You do not want to say, for example, a person weighs 1,000kg).

7) If everything seems logical, CONGRADULATIONS, if not, redo.

The only thing that changes in this case is that there is no x and y components and some concepts must be combined.

*Requisites: Firm grasp of Trigonometry, Vectors, Newton’s Laws (at least conceptually), and basic understanding of reality.

Seven Steps To Victory:

Steps:

1) Draw out the problem.

2) Draw it out as a diagram of forces (such as example 4).

3) List all known variables.

4) Solve for what you are trying to find using variables, and using vector rules.

5) Plug in the information you have and solve for unknown variables.

6) Check using logic (You do not want to say, for example, a person weighs 1,000kg).

7) If everything seems logical, CONGRADULATIONS, if not, redo.

Below are the two guides I have written for this topic, they have examples of each force and walk through each problem step by step.

1) If an object does not interact with any other objects (or net force), it is possible to identify a reference frame in which the object has zero acceleration. In common terms: Every body persists in a state of uniformity unless compelled to change that state by a net force being impressed on it.

Example of Newton’s First Law – Look around you, anything that is not moving has no net force, meaning there is no net force being impressed upon it. 

Ways to Remember – First Law is boring, nothing happens.

2) ∑F = ma (∑ – the sum of or net force; ‘a’ is a vector, or has direction in this case)

Example of Newton’s Second Law – Go ahead and push an object near by, notice how you have caused an acceleration to the object (you made it move from rest). That means that in turn you have moved that mass through some distance, which is defined as a force. The direction that you pushed the object was also the same direction which the force was applied. Seems obvious, but there you have it.

Ways to Remember – First has nothing, Second you add something, adding acceleration. F = ma, ma is only two variables.

3) To every action there is an equal, but opposite reaction. That is, if an object exerts a force on another, the force on both objects is equivalent.

Example of Newton’s Third Law – Go ahead and quickly move both hands together and clap, when that happens both hands come to a quick stop and there is no more movement. This is an example of Newton’s third law. Both hands cease movement because both hands are applying the same force towards one another which cancel each other out. If you do not understand this concept please revisit a video or notes on vectors.

Ways to Remember – First is nothing, Second you add acceleration, Third you cancel it. F – F = 0.

A • B = |A| |B| Cos θ

Or in words the dot product is the magnitude of both vectors multiplied by one another (since the |A| of vector A removes the direction creating a scalar quantity, same goes for |B|), what this means is the dot product:

a) Uses to vector quantities to create a scalar quantity.

b) Is the the magnitude of two (or more vectors) multiplied by the Cos Θ between them.

Required Understanding Previous: Trigonometry, Calculus

In the video below there is an explanation of dot products (sorry, it was a rough day when I made this video):

1)  Identify x-axis, y-axis (& z-axis if required).
*Usually North, South, East, and West or Up, Down, Left, and Right

2) Break all components of each vector down so they may be added or subtracted.

3) Add/Subtract all of the components.

4) When all of the components are added/subtracted there should be no more than four new components.

5) Use the rules of trigonometry to solve for the new vector  = C √((A^2)+(B^2))

Requirements to understanding: A fair understanding of Trigonometry.

In the video below there is an explanation of vectors for basic college and high school physics.

ž   Learning to distinguish our body’s tissues and be able to properly identify them and accurately interpret their different functions.

What is a Tissue?

ž   The study of tissues is called histology (I always like to think of flipping through a history text—the book being our body and all of the pages are its tissues—but that’s just me!)

ž   A tissue is a cell grouping that is similar in structure and function.

ž   Four primary types of tissue:

1.    Epithelium
2.    Connective
3.     Nervous
4.     Muscle

Not to worry, all have very distinct features!                                       

I am hoping to create a guide that will identify each epithelial tissue individually—complete with a description of its appearance, its unique function, and its specific location in the body.

*PRO-TIP – If you are looking for conversions between English and SI units, I would recommend just typing it in on Google. Example: type in 1ft = m and Google will calculate what one foot is in meters.
