Biomechanics Basics
The study of mechanical laws relating to the movement of living organisms.
What are Biomechanics
An object at rest stays at rest unless acted upon by an unbalanced external force.
What is Newton's First Law of Motion?
The systematic study of human walking and movement patterns.
What is gait analysis?
Designing workspaces for optimal body mechanics.
What is ergonomics?
This type of lever has the fulcrum in the middle, with the load and effort on opposite sides
What is a first-class lever?
This is one of the fields of study/professions biomechanics combines.
What is Engineering, Physics, or Biology?
F = ma belongs to this law.
What is Newton's Second Law of Motion?
60% of the walking cycle.
What percentage of the gait cycle is the stance phase?
Creating artificial limbs that mimic natural movement.
What is the purpose of prosthetics in biomechanics?
Your calf muscles lifting your body onto your toes is an example of this class of lever.
What is a second-class lever?
The point where body mass is evenly distributed.
What is Center of Gravity
For every action, there is an equal and opposite reaction.
What is Newton's 3rd Law?
When the foot is off the ground and moving forward.
What is the swing phase?
Role of biomechanics in physical therapy?
Rehabilitating injuries through corrective exercises
A lever with a mechanical advantage greater than 1 means the effort force is _____ than the load force.
*What is less?* (or *What is smaller?*)
Push or pull acting on an object. F=ma
What is a force?
A soccer ball stays put until kicked, then continues rolling until friction stops it.
What is an example of Newton's First Law?
This is when both feet are in contact with the ground
What is double support?
How does biomechanics help prevent injuries? (I know, this one is flipped)
Identifying movement patterns that may lead to injuries and designing safer equipment.
Explain why the human arm uses third-class levers even though they have low mechanical advantage.
What is because they allow for speed and range of motion?
Body segments that act as mechanical levers to create movement. (Think about the parts of the body that make up levers)
What are bones and joints>
It requires less force to accelerate a small car than a large truck.
What demonstrates Newton's Second Law?
This is an application/use for gait analysis
What is injury prevention, performance enhancement, rehabilitation, etc
This tool allows people to exercise, move, and perform while tracking data such as heart rate, respiration rate, movement patterns, steps, forces, etc.
What is wearable technology?
Calculate the mechanical advantage of a lever where the effort arm is 2 meters and the load arm is 0.5 meters
What is 4?
