1. A body is placed on a rough inclined plane. Why does the frictional force decrease with the increase of angle of inclination?
2. When a moving bus stops suddenly, the passengers fall forward. Why does this happen?
3. The lesser the mass, the greater the acceleration for the given value of force. Why does this happen?
