Question

An aeroplane flying straight at a speed of 200km/hr describes

1) circulatory motion
2) curvilinieer motion
3) rectillinier motion
4 ) periodic motion

Answer 1

Answer:

An aeroplane flying straight at a speed of 200km/hr describes periodic motion.

Answer 2

Answer:

period motion

Explanation:

Any motion of a system that is continuously and identically repeated. The time T that it takes to complete one cycle of an oscillation or wave motion is called the period, which is the reciprocal of the frequency. See pendulum; simple harmonic motion. From: periodic motion in A Dictionary of Physics
