You always give great examples which make it much easier to understand. Especially considering we did an assignment that briefly mentioned the confusion of Newton's laws. Great video.
When going up and landing, you leave and land on the ball and toe of the foot. The metatarsal, tibia-fibula, and femur are the 3 primary segments of extension and contraction. They extend and contract like an accordion.
I love your videos! I was wondering, if you could link me to some practice problem sets with an answer key. I am starting HES 307: Biomechanics ,Principles of human movement in January 2022 and have been watching lectures nonstop and trying to give myself the best chance of success. I haven't been a college student in 5 years and I am a little nervous. Thanks and hope to hear back from you soon .
Hello Dr.Goodin, thank you so much for producing the content you make to help new learners like myself enter the world of deeper movement understanding. I have a question regarding the validity of Newton's Laws of Motion, how is it possible that something discovered by a young 20 year old in the 1600's still be so widely accepted today without any alternatives to these laws?
So far, no legitimate scientific inquiry has been able to offer an alternative explanation that has held up over time! Of course, Einstein's special and general theories of relativity compliment Newton's laws and are also more accurate for obscure cases. But, to be skeptical of an idea due to the age or era of its creator is to conflate the idea's veracity with your own notion of human progress or age-dependent capacity.
For the geeks: At minute 11:30: Here I am skeptical about the extent to which it is internally eccentric. In other words, how much the quadriceps femoris works eccentrically. I tend to think that this is less eccentric, and much more isometric.
Interesting... Could one theoretically land softly enough that the peak impact force would be smaller than the peak launch force if the range of motion of the eccentric contraction upon landing was larger than the range of motion of the concentric contraction of the jump? This question is beyond my conceptual brainpower.
breaking = braking. My bad! 😉

Thanks Anthony!
This definitely helped me grasp Newton's Laws! The text book was a little confusing so the clarifications from this video were awesome!
Going step by step helped me understand the vertical jump much better
The title is right! This video does make sense of Newton's laws!
The graph really helped thank you
This video definitely helps me understand the dynamic structures of newtons laws. thank you
Thank you for the use of the graph it really helped.
This helps so much!! thank you!
Thank you this really helps
This helping better understand Newton's laws during movement!
Thanks for the educational videos
Thank you
Seeing the graph helped to understand gravitation in a real world example.
good stuff!

Can you tell me what part of the curve is the peak impact force and peak active force please.

"If you're from Canada forgive me" _the violation_ 😂
Would impulse-momentum relationship be relevant during the breaking - push off phase?

15:00 Poor presentation, showing the bottomline at the end without showing the forces. Your chart numbers are NOT legible at all.
7:50 LAWS are manmade conventions. Physics==Nature does is NOT bound by manmade concepts and their limits!!!
a little handwavey at times
