TEKS:P.8A Periodic Motion Vocab

What is a simple pendulum?

• A device that can demonstrate simple harmonic motion when its bob is pulled to one side and released, causing it to swing back and forth.

• A type of clock that uses a swinging arm to measure time accurately.

• A mechanical device that converts linear motion into rotational motion.

• A structure used to support a weight in a stationary position.

What does Hooke’s Law state?

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

• The force acting on a spring is inversely proportional to the amount the spring is compressed.

• The force acting on a spring is equal to the mass of the spring times the acceleration due to gravity.

• The force acting on a spring is constant regardless of the amount it is stretched.

What is resonance in periodic motion?

• 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.

• A type of motion that occurs when an object is at rest and experiences no forces acting on it.

• A phenomenon where an object moves in a straight line without any oscillation or vibration.

• A condition where an object vibrates randomly without any regular pattern.

What is simple harmonic motion?

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

• A type of motion that occurs in a straight line without any forces acting on it.

• A motion that involves constant acceleration and is not periodic.

• A motion that occurs when an object moves in a circular path at a constant speed.

What is amplitude in periodic motion?

• The maximum distance an object moves from the equilibrium position.

• The speed of the object at its highest point.

• The total distance traveled by the object in one cycle.

• The force exerted by the object during motion.

What is a period in periodic motion?

• The distance traveled by an object in one cycle.

• The maximum speed of an object in motion.

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

• The force acting on an object in motion.

What is periodic motion?

• Any motion that repeats in a regular cycle.

• Any motion that occurs randomly without a pattern.

• Any motion that is linear and unchanging.

• Any motion that is caused by external forces.
