Newton's Second Law of Motion  Physics  Infinity Learn NEET  Summary and Q&A
TL;DR
Newton's second law of motion states that acceleration is directly proportional to the net force applied and inversely proportional to the mass of the object.
Key Insights
 👮 Newton's second law of motion states that acceleration depends on the net force applied and the mass of the object.
 💆 The acceleration is directly proportional to the net force and inversely proportional to the mass of the object.
 🤒 Force is measured in Newtons, with 1 Newton defined as the force required to give a 1 kilogram mass an acceleration of 1 meter per second squared.

Do you remember the Newton's first law of motion? It says that an object will continue to do what it's doing unless acted upon by an unbalanced force or some net force! Now the important question is what happens when there is net force acting on an object? That's precisely what the second law of motion will discuss. Do you remember understanding th... Read More
Questions & Answers
Q: What does Newton's second law of motion state?
Newton's second law of motion states that acceleration is directly proportional to the net force applied and inversely proportional to the mass of the object.
Q: How does the acceleration depend on the net force?
The acceleration is directly proportional to the net force. If the force applied is greater, the acceleration will be greater. If the force applied is lesser, the acceleration will be lesser.
Q: How does the acceleration depend on the mass of the object?
The acceleration is inversely proportional to the mass of the object. If the object has lesser mass, the acceleration will be greater. If the object has more mass, the acceleration will be lesser.
Q: What are the units of force?
The unit of force is Newton (N), which is defined as the amount of force required to give a 1 kilogram mass an acceleration of 1 meter per second squared.
Summary & Key Takeaways

Newton's first law states that an object will continue to do what it's doing unless acted upon by an unbalanced force.

If the forces are balanced, the object will remain at rest or continue to stay in motion at the same velocity and direction.

If the forces are unbalanced, there will be acceleration, and the acceleration depends on the net force and the mass of the object.
