Ignore?
oscillation
any repeating motion
cycle
a series of changes produced in sequence that recur periodically.
period
…, it is the time between successive oscillations of the system (see figure 2).
Frequency
#cycles/second
amplitude
… the object from its equilibrium position
Damping
An influence that causes an oscillating object to lose energy and eventually come to a rest on its own.
driving
Forces that try to cause motion: In the case of falling it would be gravity (weight). In the case of a car it would be the force from the engine (through the friction on tir…
restoring force
in a physics context, is a variable force that gives rise to an equilibrium in a physical system. If the system is perturbed away from the equilibrium, the restoring force will tend to bring…
equilibrium
1)starting point of SHM, object is in _______, fnet equals zero
work
a force acting upon an object to cause a displacement. (key words: force, displacement, and cause)
Potential Energy
(mass) x (g) x (height)
kinetic energy
a running dog
Power
(physics) the rate of doing work
work-energy theorem
The energy associated with the work done by the net force does not disappear after the net force is removed (or becomes zero), it is transformed into the Kinetic Energy of the body.
energy conservation
A principle stating that the total energy of an isolated system remains constant regardless of changes within the system.
displacement
A change in position (delta p).
phase
_______ is the degree portion of a cycle at any given time
