Newton has explained it fully in his first law that a body will remain at rest or continue to move with constant velocity in a straight line, unless acted upon an external net force.
You can therefore draw two conclusions-
1.if the velocity is changing, a net force is being applied.
2.if the direction is changing(travelling along a curved path) then a net force is being applied.
In the absence of net force, the body must move with constant velocity, and in a straight line

Answer:
No, it is not possible to move in a curved path in the absence of the force.
Explanation:
Because in the absence of force body will not change its direction to move in a curved path, and it will continuously move in a straight line. This result is based on Newton's first law, which states that if there no acting force on a body, then it will remain at rest or in constant velocity motion. To change the state of the motion, the net for on body must be other than the zero.
The force always acts on a point. When there are multiple forces acting on a body, then the net force is calculated by the vector sum of all the forces.
