Question

Define the term periodic motion give two example of periodic motions that can be used ti measure time.​

Answer 1

Answer:

Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave. Answer: ... Two examples are ' Pendulum' and ' Tuning Fork'.

Answer 2

Answer:

• Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.  Two examples are ' Pendulum' and ' Tuning Fork'.

• Periodic motion is a motion which is repeated by a body in equal intervals of time.The interval or cycle for the repetition of motion is known as a period and the number of periods per unit time is known as frequency of that body performing periodic motion.

Example of periodic motion are tuning fork, swing in motion, bouncing ball.

• Rotation of earth about axis
• Revolution of earth around sun and moon.
• Simple harmonic motion of bob tied to a fixed point used to measure its time period.
