1. Increase the mass of the object.

2. Increase the velocity of the object.

Momentum is a vector quantity that is defined as the product of the mass of an object and its velocity. It is a measure of how much force is required to stop a moving object.

By increasing the mass of an object, you are increasing the amount of force that is required to stop it. This means that the momentum of the object is also increased.

By increasing the velocity of an object, you are increasing the speed at which it is moving. This also means that the momentum of the object is increased.

Therefore, by either increasing the mass or the velocity of an object, you can increase its momentum.
