Detailed explanation-1: -p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.
Detailed explanation-2: -Yes, mass is directionally proportional to momentum. That is because the equation for momentum is mass times velocity. This can also be written as p = m*v where p is momentum, m is mass and v is velocity. Therefore, if mass is doubled and velocity stays the same, then momentum is also doubled.
Detailed explanation-3: -According to newton’s second law of motion rate of change of linear momentum is directly proportional to the force applied. Momentum is the product of a particle’s mass m and velocity v.
Detailed explanation-4: -For a given constant force and displacement, velocity is always inversely proportional to root of mass.
