An object is moving across a surface, but it does not gain or lose speed. which best describes the object’s force? the net force is positive. the net force is zero. the positive force is greater than the negative force. the negative force is greater than the positive force.

the net force is zero.

Explanation:

According to Newton's second law, the acceleration of an object is proportional to the net force acting on the object:

where

F is the net force

m is the mass of the object

a is the acceleration

In this problem, the object is moving without gaining or losing speed. It means that its speed is constant, so the acceleration is zero: therefore, the net force must be zero as well.
