Momentum is defined as the product of an object's mass and its velocity. Therefore, if the momentum of a moving object is increased, either the mass or the velocity (or both) must have increased as well.

Speed is directly proportional to velocity, so if the momentum has increased, it follows that the object's speed must have also increased.

Kinetic energy is a measure of the energy of motion, and is directly proportional to the square of an object's velocity. Therefore, if the momentum has increased (and the mass remains constant), the object's kinetic energy must have also increased.

Acceleration refers to the rate of change of an object's velocity, and is not directly related to momentum. Therefore, there is no reason why an increase in momentum must also lead to an increase in acceleration.

Potential energy is associated with an object's position or configuration and is not related to its momentum.
