What is Newton\'s second law and also prove it. |
|
Answer» newtons\'second law is that change in momentum is directly proportion to force applied on an body.proove=suppose you applied the force on an object the object move and you less the mass of body less force will be reqired and you increase the mass large no. of force is reqired. Newton\'s second law of motion derives the relationship between force and aceralation for example when passengers standing in running bus share motion of the bus it means that the passengers in running bus are also moving with the same speed and in same direction wheb the bus stops suddenly the lower lower part of passengers body cones to rest while the upper body portion continues to remain in motion as a result the passenger are suddenly thrown in the forward directionwhen the running bus stops suddenly |
