If an object is stationary and another object is approaching it with a constant velocity, the state of motion of the first object will depend on various factors such as the nature of the interaction between the objects and the forces acting upon them.
In the absence of any external forces or interactions, the first object will remain stationary as the second object approaches it. This is based on Newton's first law of motion, which states that an object at rest tends to stay at rest unless acted upon by an external force.
However, if there is an interaction or force between the two objects, the first object may experience a change in its state of motion. For example:
If the approaching object collides with the stationary object and imparts a force, the first object may start moving in the direction of the applied force or be displaced depending on the magnitude and direction of the force.
If there is a gravitational force between the objects, such as one object being attracted to another, the stationary object may be pulled towards the approaching object. The resulting motion will depend on the masses and distances involved.
If there are other forces acting on the objects, such as friction, air resistance, or electromagnetic forces, the stationary object may experience an external force that can cause it to move or change its state of motion.
In summary, the state of motion of the first object, when approached by another object with constant velocity, will depend on the forces and interactions involved. In the absence of any external forces, the first object will remain stationary. However, the presence of forces or interactions can result in a change in the first object's state of motion.
