Physics spring/pendulum Flashcards
period (T)
time/ osc
frequency
1/ Period
Factors that could e change on a pendulum
mass
length
amplitude
gravity
factors that affect period on pendulum
length (directly). decrease freq. bc of shorter arc distance to cover
gravity (inversely related). causes acceleration which increases velocity
period formula pendulum
2pi%L/g
what doesn’t affect period of pemdulum
mass bc gravity affects all mass the same. larger mass will have larger force
amplitude: increase=increase velocity=increase distance. cancells out
Factors that affect spring
Spring Constant mass length gravity amplitude=distance from equilibrium point)
factors that affect period of spring
mass (direct)
strength (direct)
gravity (for vertical only)
spring force formula
Kx
spring constant (k)
N/m
how difficult is the spring to strength/compress. increase: decrease in period.
tough: faster oscilation
mass for spring
larger: more mass: more difficult to move. increase mass: increase inertia: increase period
spring-compressed
no net force accel/velocity: right -x v=o max=a
spring-equilibrium
