Motion
Motion and Time of Class 7
Motion is one of the key topics in physics. We know everything in the universe moves with respect to some body. It may be only a small amount of movement and very slow, but movement does happen everywhere. When an object changes its position with elapse of time in respect to a stationary object, such as a building, electric pole, etc., the object is said to be in motion.
Main types of simple motion
There are four types of motion:
- Translation motion
- Rotation Motion
- Oscillatory Motion
- Random Motion
