### Motion And Time Quiz For 7th Grade students We usually see many things in our daily life, in which some objects are in motion and some things are in a rest state. Any object in motion when an object changes its position over time. According to physics, the definition of time, time is what a clock reads. In the present time, it has become very easy to find the time, but in ancient times, time was detected using natural phenomena. For example, the sun rises every morning, then, the time between one sunrise and the next was known as one day. Similarly, the time from one full moon to the next full moon was called a month.
