Question

rate of change of Linear Momentum is called what​

Answer 1

rate of change of Linear Momentum is called FORCE

Answer 2

Answer:

Force is said to be the rate of change of linear momentum.

Explanation:

• The product of the mass and the velocity of a body is known as momentum.
• It is also a vector quantity.
• According to newton's second law of motion, a force that is not balanced when applied to a body, then it is known to be directly proportional to the rate of change of momentum.

                   Rate of change of momentum = $\frac{mv-mu}{t}$

where,

mv = final momentum

mu = initial momentum

And according to the above statement,

                             $F=k(\frac{mv-mu}{t})$

where,

k = proportionality constant = 1

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

we know that,

                      $\frac{v-u}{t} = acceleration$  

                           ∴    $F = ma$                        (a = acceleration)

Hence we can conclude that the rate of change of momentum is the same as the force applied to an object.
