When a keep two blocks one over another...And apply a foce on the block which is below...Why does the upper block falls down..Why dosent it move with A? assumin there's no friction between A and B?
Why do you think? Which of Newton's Laws might apply to this situation?Shardul Khare said:When a keep two blocks one over another...And apply a foce on the block which is below...Why does the upper block falls down..Why dosent it move with A? assumin there's no friction between A and B?

Shardul Khare said:No idea
Shardul Khare said:First Law states that A body continues to be in motion or at rest until an unbalanced force is acted on it
Second law-sEOCND LAW - f=MA
Third Law: Every action has an equal and opposite reaction
ZapperZ said:Now, look at your question, and then look at the First Law. In particular, if there's no friction between A and B, how would the First Law be relevant here?
Zz.
RIght. And what happens to a body with no force acting on it?Shardul Khare said:The Normal and Mg cancel out,no friction means no other force acting on B,right?
yes, that's where I was leading you in post #4Shardul Khare said:It remains unaccelerated, So when we apply force on the lower bloack,the upper block will stay where it is and the lower block will mover forward, am i right?
Thank you :)phinds said:yes, that's where I was leading you in post #4
Newton's Laws of Motion are a set of three physical laws that describe the relationship between the forces acting on an object and its motion. They were developed by Sir Isaac Newton in the late 17th century and are considered fundamental principles in the field of classical mechanics.
Newton's First Law, also known as the Law of Inertia, states that an object at rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an external force.
Newton's Second Law, also known as the Law of Acceleration, states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. In other words, the greater the force applied to an object, the greater its acceleration will be, and the more massive the object is, the less it will accelerate.
Newton's Third Law, also known as the Law of Action and Reaction, states that for every action, there is an equal and opposite reaction. This means that when two objects interact, the forces they exert on each other are equal in magnitude and opposite in direction.
Newton's Laws of Motion are applied in many aspects of everyday life, from simple activities like walking and driving a car, to more complex systems like space travel. They help explain and predict the behavior of objects in motion and are essential in the design and functioning of machines and structures.
