Question

any one define Newton second law of motion?​

Answer 1

Newton's second law of motion states that -

F is directly proportional to -

$\huge\frac{mv - mu}{t}$

F=

$\huge\frac{m(v - u)}{t}$

F= ma

( F = Force)

(m= mass)

(u = initial velocity )

(v= final velocity )

(t = time)

Answer 2

Newton's Second law of motion gives us a relationship between 'force' and 'acceleration'.

Newton's second law of motion also gives us a method of measuring the force in terms of mass and acceleration. When a force acts on a body, it produces acceleration in the body, the acceleration produced may be positive or negative.

Statement: The acceleration produced in a body is directly proportional to the force acting on it and inversely proportional to the mass of the body.

The force acting on a body can be calculated by using the formula: F=m×a.

We can also write the equation F=m×a as:

a=F/m

If a mass of a body is doubled, its acceleration will be halved. And if the mass is halved then acceleration will get doubled and the provided force remains the same.
