Non-linear motion is motion that is not in a straight line. When analysing linear and non-linear motion, … [Read more...] about What is Motion and Types of Motion

Measurement of Time Using Periodic Motion
Measurement of Time Using Periodic Motion Any object that is moving is said to be in motion. In order to measure time, we need a motion that repeats itself in equal intervals. Such a motion is called periodic motion.Some examples of periodic motion are the rotation of the Earth about its axis, the revolution of the Earth around the sun, the revolution of the moon around … [Read more...] about Measurement of Time Using Periodic Motion
