Here's why:
* Newton's First Law of Motion: This law states that an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
* Uniform Velocity: Uniform velocity means the object is moving at a constant speed in a straight line.
* Net Force: Net force is the vector sum of all forces acting on an object.
Since the object is moving with uniform velocity, it's not accelerating. Acceleration is a change in velocity, so if the velocity is constant, the acceleration is zero. According to Newton's Second Law of Motion (F = ma), if the acceleration is zero, the net force must also be zero.
In summary: A body moving with uniform velocity is not experiencing any unbalanced forces acting upon it. The forces are balanced, resulting in a net force of zero.
