What is the second law of motion in simple words?
Newton’s second law states that the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object. The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body.
What is Second law of motion for Class 9?
Newton’s Second Law of Motion It states that the rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts.
What is the second law of motion class 8?
Newton’s Second Law of Motion Newton’s 2nd law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the object’s mass.
What is Newton’s second law of motion Wikipedia?
Second law Newton’s second law describes a simple relationship between the acceleration of an object with mass m, and the net force F net acting on that object: The net force and the object’s acceleration are both vectors, and they point in the same direction.
What is the second law of force?
Newton’s second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
What is the second and third law of motion?
Newton’s laws of motion relate an object’s motion to the forces acting on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
What is the second law of motion according to Ncert?
These qualitative observations lead to the second law of motion expressed by Newton as follows : The rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts.
What is Newton’s second law of motion answer key?
Newton’s second law of motion is F = ma, or force is equal to mass times acceleration.
