PHYSICS Flashcards
rate of change of angular displacement over time (w)
angular velocity
magnitude of angular velocity
angular speed
magnitude of angular velocity
angular speed
object’s resistance to rotational motion
moment of inertia
rotational force applied to an object
torque
region around the mass, force due to gravity
gravitational field
object behaved when subjected to restoring force
simple harmonic motion
attached to a string or rod under the influence of gravity
simple pendulum motion
gradually decreasing amplitude over time
underdamped motion
movement along the direction of wave propagation
longitudinal motion
how far an object moves from its resting position during its cycle
amplitude
change of volume with temperature
coefficient of volume expansion
no intermolecular forces and occupy no volume
ideal gas property
turn back to its initial state
reversible process
no net force a
or rotation
static equilibrium
2 systems with 3 systems in thermal equilibrium
zeroth law of thermodynamics
disorder or randomness in a system
entropy
entropy can never descrease over time
2nd law of thermodynamics
how loud a sound appears to human perception
intensity of sound
lowest frequency produced by vibration and determines pitch
fundamental frequency
pressure applied is equal
pascal’s principle
cross sectional area and flow velocity is constant
principle of continuity
increase in fluid speed, decrease in pressure
bernoulli’s equation
t² is proportional to r³
kepler’s 3rd law of planetary motion
