Intro to Linear Kinematics: Displacement, Velocity, & Acceleration

In this video I'll explain the concept of kinematics as it relates to biomechanics, and we'll also examine inter-related concepts of velocity, displacement, and acceleration.

Dr. Jacob Goodin is a professor of kinesiology at Point Loma Nazarene University (PLNU), and holds a PhD in Sport Physiology and Performance from East Tennessee State University. He has over a decade of experience as a strength and conditioning coach and sport scientist from the high school to NCAA Division I levels. In addition to his role as a professor and research mentor, Dr. Goodin directs the Athlete Monitoring Initiative at PLNU, which provides testing and monitoring services to over 200 athletes yearly as well as research opportunities for kinesiology students.

I appreciate you writing out a lot of the math equations and explaining in depth how to do them!

I have a test tomorrow and I am a 9th grader who tried to take the hardest science class our school offers. Honors physics. I don’t understand any of it. My teacher didn’t teach us anything so now I am flipping out about my test.

I really enjoyed your soccer example at the end

[sydneyspradley]

I love your style of teaching! For one that struggles with math and understanding concepts, I find your lessons easy to follow! I think your teaching hits many different learning styles :)

[dimitricarrion]

I liked the organization of the soccer example. Very easy to understand when you went step by step.

[peytonyoshida]

Seeing all of the variables in one place really helped me to understand the relationship between kinetics and kinematics.

[nicolelewis]

This helped me understand the math equations so much better! Thank you!

[youtubenerd]

You explain this so easy, i think you conquered my fear of math since i have dyscalculia. Thank you!

[Frejamuffin]

On the very last equation where did you get the 10m/s over 5? As i thought the change in velocity was 30?

Hello, I have this question. I have data of horses. vertical acceleration. If these values are registered by ms and I have -0.4, 1.2, 3.1 and -0.08 m/s2. How can I get a measure of each horse? may I take just the average? or Should I do another calculation? Thanks a lot for your help.

I wish when I read the book it made as much sense as when you say it lol

[Yasmin-qewf]

These powerpoint slides summarize the sections of the book in a much more easier way to understand.
