Question

What is the expression for Newton's second law
of motion ?​

Answer 1

Equation for Newton's second law of motion

F= m× a

F= force

m= mass

a = acceleration

Answer 2

Answer:

Newton’s Second Law of Motion

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.

Second Law of Motion Formula

Let us consider an object of mass m, moving along a straight line with an initial velocity u. Let us say, after a certain time t, with a constant acceleration, the final velocity becomes v. Here we see that, the initial momentumLaw Of Motion

The final momentum

Law Of Motion

The change in momentum can be written as

Law Of Motion

As we know, the rate of change of momentum with respect to time is proportional to the applied force. The applied force

Law Of Motion

Or,

Law Of Motion

as acceleration (a) = rate of change of velocity with respect to time.
