Question

Can anybody explain the 1,2,3 Newtons law????

Answer 1

The 1 st law : A body will remain at rest or will keep moving in a straight line unless it is forced to do so by an external force. A book lying on your table will remain there only for 10000 of years to come unless someone picks it away. The 2 nd law: This is basically a mathematical law. It says that Rate of change of momentum is directly proportional to the force that is being applied, and it occurs in the direction of force . Or it can be restated as the applied force (F) is directional proportional to the rate of change of momentum ( change in momentum / time). The 3rd law: I love this law. This is really simple to understand. It says, in simple words that to every action there is an equal and opposite reaction. Like..you wear roller skates and push a wall. You will notice that the wall will push you back (in the opposite direction) and the harder you push,the more will you go back( equal force). Hope it helps. Do ask a question if you have further doubts
