Explain “Momentum gives more information than velocity alone”

Explanation

Example 1 : if a pebble and a stone are thrown with same velocity to hit a man. Then it is very as the velocity of both the object is same .
We can know the force on object by studying the change in momentum of the object
By knowing the mass we can say that momentum of stone is greater than pebble hence stone is going to cause more damage
Example 2 : let us assume that a car and truck are stati on horizontal road. To bring them interval car required velocity in equal time interval car required less force and truck required more force .Also it they are moving with same velocity to bring them to rest car requires less retarding force than to bring truck to rest in same time interval
thus to determine effect of force momentum gives more inoformation than velocity alone
