Lab: The Physics of Bipedalism
I need help answering these lab questions with detailed
explanations and diagrams if possible :
1. What are the different types of
bipedalism?
2. What Are the Forces Acting on Our Feet while Walking
& running?
3. How do we walk & run? how do we accelerate
forward?
4. How does momentum help us walk and run?
( question 4 is the most important one If you can provide
an example with some calculations that would be great, or a
diagram)
5. Explain the cycle of a stride.
