hooke’s law
describes elongation & how the force is related to the distance
spring (restoring) force
F=-kx, where k is the spring constant and x is the displacement of the spring from its unstrained length. The minus sign indicates that the restoring force always points in a direction opposite to the displacement of the spring from its unstrained length (newton’s law of action & reaction).
elongation
angular frequency
because ‘w’ is directly proportional to the frequency f, w is often called the
period
the time required to complete one cycle for any object in simple harmonic motion
simple harmonic motion
amplitude ‘A’
the maximum displacement from equilibrium position
elastic PE
the energy that a spring has by virtue of being stretched or compressed (kx^2/2)
simple pendulum
a pendulum that consists of a particle mass ‘m’, attached to a frictionless pivot by a cable of length ‘L’ and neglible mass
physical pendulum
a pendulum of a rigid extended object
length ‘L’ for a physical pendulum is the distance between the axis at ‘P’ and the center of gravity of the object
