Detailed explanation-1: -The momentum of an object depends on both mass and velocity. Heavier products tend to produce a greater force and thus have greater momentum. Momentum also depends on how fast the object is travelling. For example, a faster car will have a greater momentum than a slower one.
Detailed explanation-2: -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. A large, fast-moving object has greater momentum than a smaller, slower object.
Detailed explanation-3: -The momentum, p of an object is defined as the product of its mass, m and velocity, V. Momentum = Mass x Velocity. That is, p = mv.
Detailed explanation-4: -Momentum depends on how much mass things have and how fast they are moving. When things crash into each other, momentum is transferred.
