Expert Answer:

Speed velocity and momentum are completely different terms.
Speed is a scalar quantity, and defined as distance travelled per unit time.
Velocity is a vector quantity, whose magnitude gives the speed with which a body is travelling and also has a direction associated with it.
Momentum is also a vector quantity, and defined as, P = mv (mass x velocity)
