how do we tell if something is at rest or moving in a constant velocity when the net force is zero? like when you pull a box upwerd with the force that is equel to the weight of the box, it goes upwerd in a constant velocity right? but why when we push the box forward and the net force is zero, it stays at rest? (why does it stays at rest when the friction is equel to the force) tell me the difference​



Answer :

MathPhys

Answer:

Newton's first law of motion

Explanation:

Newton's first law of motion says that an object at rest stays at rest, and an object in motion stays in motion, until acted upon by an unbalanced force. If the net force on an object is zero, then its acceleration is zero, and its final velocity will simply be the same as its initial velocity. So if the object is initially at rest, it will stay at rest. And if an object is initially moving, it will continue moving at the same speed and direction. The difference is simply the initial state of the object.
