what matter has the strongest intermolecular bond?
solids
why understanding fluid dynamics is essential?
Are essential to life
- Human body: 65% water
- Earths surface: 2/3 water
- Atmosphere extends 17km above the earths surface
how is kinematics applied in medical field?
Motion measurement can be used to evaluate functional performance of limbs under normal and abnormal conditions.
Kinematic knowledge is also essential for proper diagnosis and surgical treatment of joint disease and the design of prosthetic devices to restore function.
what is the fundamental of formula describing movement?
Acceleration = change in velocity/time take
what is a statement that is incorrect about newtons 1st law of motion?
the more mass an object has, the less inertia
if force applied on an object is doubled and mass to half. what will the ratio of its accelerations?
1:4
if two bodies exert forces on each other. these forces are equal in magnitude and opposite in direction. this is a description of what law
newtons 3rd law
how many volts would it take to push 5 amp through a resistance of 15 ohm
75 volts
how to calculate ohms law
To find Voltage:
V=I×R
To find Current:
I = V divided by R
To find Resistance:
𝑅 = V divided by I
give examples of kinemtaics and dynamcis
Osteokinematics: the manner in which bones mov
Moving a car. The change in location caused due to dynamic force acting on the vehicle responsible for its motion and acceleration.
