Life sciences - week 11 Flashcards
(15 cards)
Kinematics?
the study of motion without regard for the cause
E.g. osteokinematics
Dynamics?
studies objects with acceleration
Kinematics vs Dynamics
Kinematics is the study of motion without regard for the cause. dynamics is the study of the causes of motion
What are the differences between potential and kinetic energy?
Kinetic energy is the energy processed by an object due to its motion
Potential energy is the energy stored in an object due to its position (gravitational energy)
three examples of kinetic energy
Car in motion, playing football, high speed train
three examples of potential energy
energy in a battery, rubber band stretch out out between two fingers, water behind a dam wall
Formula describing movement?
Acceleration = change in velocity/time taken
Five components of motion
Position
Speed/velocity
Acceleration
Distance/displacement
How is kinematics applied in medical field?
A motion measurement that is used to evaluate functional performance of limbs under normal and abnormal conditions
- essential for chemical diagnosis
Why is fluid dynamics essential?
Fluids are essential to life:
Human body 65% water
Earths surface 2/3 water
Atmosphere extends 17km above the earths surface
What is fluid flow?
a substance in the lipid or gas phase
Which matter has the strongest intermolecular bond?
Solid
two types of fluid flow?
Steady flow and turbulent flow
examples of fluid mechanics applications
Boats, Aircraft, Cars, Submarines, Insulin pump
What is Bernoulli’s principle
pressure decreases when the flow speed increases
