Question

state and explain Newton's second low of motion
​

Answer 1

Answer:

Newton's second law of motion defines that the acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. 

Explanation:

Newton's second law of motion can be formally stated as follows: 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 mass of the object.

Or it is easy to say that it basically defines:-

zero net force.The Law of Accelerated Motion. The acceleration of a system is directly proportional to the net force acting on the system and is inversely proportional to its mass.

Answer 2

Answer:

Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. ... So, the force/mass ratio (from the equation acceleration = force/mass) is the same for each. Therefore, the acceleration is the same and they reach the ground at the same time.

Explanation:

Newton’s second law of motion states that the force exerted by a body is directly proportional to the rate of change of its momentum. For a body of mass ‘m’, whose velocity changes from u to v in time t, when force ‘F’ is applied.
