Momentum =mass x velocity.Rate of change of momentum =change in momentum/time ie mv-mu/t  ie same as m (v-u)/t which is same as m x a where  m is mass  and a is accelaration  .ie rate of change of momentum is force .it can be written as  M^1L^1T^-2
The Physical quantity which corresponds the rate of momentum is - FORCE.
Force =ma ( mass x acceleration).
rate it pls

Linear Momentum =  p = m v
Time rate of change of linear momentum = d p / dt
= d(mv) / dt = m dv/dt = m a
= Net Force acting on the object

Or,

Time rate of change of momentum = (p2 - p1) / (t2 - t1)
= (m v2 - m v1) / (t2 - t1) =  m (v2 - v1) / (t2 - t1)
= m a = Force
