Question

Application in our day to day life on the Newton's first law of motion.

Answer 1

1. first law : book stays at its place where you left it untill you shift it (external force) proving it follows law of inertia

2. gravity that acts on everybody acts on different object differently due to different masses of the object proving force = mass* acceleration

3. walking on the floor is possible due to friction as you push floor by your toes and an equal and opposite force by floor helps you to move forward
