Since the body is accelerated, the speed and velocity will vary. Momentum depends on velocity; hence the momentum will also vary. The force remains constant as F = ma.

Constant Force in Uniformly Accelerated Motion
Acceleration is the rate at which an object's velocity changes over time. When a body is said to be uniformly accelerated, it means that its acceleration remains constant. This implies that the object's velocity is changing at a constant rate.
Explanation:
- When a body is subjected to a constant force, it will accelerate uniformly.
- The acceleration of the body will remain constant throughout the motion.
- As the acceleration is constant, the velocity of the body will be changing at a constant rate.
- The momentum of the body, which is the product of its mass and velocity, will also be changing at a constant rate.
Therefore, in the case of a uniformly accelerated body, the correct option is constant force, as it is this force that causes the acceleration to remain constant. The other options such as constant speed, constant velocity, and constant momentum do not apply to a body undergoing uniform acceleration.
