Second law of Newton states that Force acting on a body is directly proportional to the rate of change of momentum...
Momentum is denoted by letter P and
calculated by P = m x v
Change in quantity = New qty - Original Qty
Here quantity can be Dispalcement ,Velocity , Momentum etc...
Change in velocity = final velocity - Initial velocity
Change in disp. = Final Disp - Initial Disp.
Similarly,
We can write
Change in momentum
= Final P - Initial P
= mv - mu
= m ( v-u )
Note that when we use word Rate...we simply divide the quantity by Time i.e, t
when we take a rate of cahnge of momentum which gives a force as follows
Rate of change of momentum
= ( Final P - Initial P ) / t
= ( mv - mu ) / t
= m [ ( v - u ) / t]
= m X a
=F
Second law of newton gives a measurement of Force which is calculated by F = m x a
