Question

1. is it possible for an object to be in motion and yet have a zero net force acting on it? explain.

Explanation:

According to Newton's first law of motion (the law of inertia), an object will remain in its state of motion (either at rest or moving with a constant velocity) if the net force acting on it is zero. When an object is moving with a constant velocity (uniform motion), the forces acting on it are balanced, meaning the net force is zero. For example, a car moving at a constant speed on a straight, frictionless road (in an idealized situation) has the driving force balanced by resistive forces, resulting in a net force of zero while still being in motion.

Answer:

Yes, it is possible. By Newton's first law, an object in uniform motion (constant velocity) has a net force of zero acting on it, as balanced forces maintain its motion state. For instance, an object moving at constant speed on a frictionless surface with balanced forces has zero net force but is in motion.
