Force and motion are interrelated factors. In fact, force leads to motion in objects.

Also, force can alter the size or shape of an object. These basic questions of physics and their laws are inherent in the Universe.

The author here explains to the teenage readers the science behind these principles in an interesting manner.

In fact,forty percent space in the book is taken up by illustrations for easy comprehension of scientific explanations.
