TEKS:P.8A Periodic Motion Vocab

Front

What is periodic motion?

Back

Any motion that repeats in a regular cycle.

Front

What is a period in periodic motion?

Back

The amount of time required for an object to repeat one complete cycle of motion.

Front

What is amplitude in periodic motion?

Back

The maximum distance an object moves from the equilibrium position.

Front

What is simple harmonic motion?

Back

A motion that occurs when the restoring force on an object is directly proportional to the object’s displacement from the equilibrium position.

Front

What does Hooke’s Law state?

Back

The force acting on a spring is directly proportional to the amount the spring is stretched.

Front

What is a simple pendulum?

Back

A device that can demonstrate simple harmonic motion when its bob, suspended by a string or light rod, is pulled to one side and released, causing it to swing back and forth.

Front

What is resonance in periodic motion?

Back

A special form of periodic motion that occurs when small forces are applied at regular intervals to an oscillating or vibrating object and the amplitude of the vibration increases.
