Question

Why do the laws of physics on macro level differ from those on the quantum level ?
Please give a quality answer. I am giving 15 points for the answer.

Answer 1

ANSWER

• WHEN WE ARE STUDYING THE LAWS FOR MACRO LEVEL THAN WE NOTICE THAT THESE LAWS ARE APPLICABLE ON THE CENTRE OF MASS OF THE BODY. BUT AT QUANTUM LEVEL THE PARTICLE ARE SO SMALL THAT IT IS NOT POSSIBLE TO CALCULATE THE CENTRE OF MASS HENCE THEY ARE ACTING LIKE A MASS LESS BODY.

• THE BASIC FORCES IN NATURE SUCH AS GRAVITATIONAL FORCE ARE NOT APPLICABLE FOR SUCH SHORT DISTANCES SO SOME MYSTERIOUS FORCE CAME INTO EXIST AT SUCH ATOMIC LEVEL WHICH ALTER THE LAWS IN PHYSICS AT MICROLEVEL.

Answer 2

Force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
