Yes, it is absolutely possible for a body to move with constant velocity while having zero net force acting on it. This is a fundamental concept in physics, known as Newton's First Law of Motion, also called the Law of Inertia.

Here's why:

* Inertia: Objects at rest tend to stay at rest, and objects in motion tend to stay in motion at a constant velocity unless acted upon by a net force. This means that if there is no net force acting on an object, its velocity will remain unchanged.

* Net Force: Net force refers to the overall force acting on an object. If there are multiple forces acting on the object, they can cancel each other out, resulting in a zero net force.

Example:

Imagine a spaceship floating freely in space far from any gravitational influence. If the spaceship's engines are off, it will continue to move at a constant velocity, even though there is no force propelling it forward. This is because there is no net force acting on the spaceship, and its inertia keeps it moving at the same velocity.

Important Note:

While the net force may be zero, it does not mean that there are no forces acting on the object. There could be multiple forces acting on the object in equal and opposite directions, resulting in a zero net force.
