Momentum is simply defined as the "Mass in Motion". That is if an object is in motion, it acquires momentum. Here is the momentum with time formula for you to find the change in time with respect to force and momentum change. Change of momentum of an object, force and time are related to each other. By knowing any of the two values, you can find the other. Use the below-given momentum with time formula to know the change of time based on the other two given values.
