Question

when two equal and opposite forces act on a robot, what is the net effect? the robot changes direction the robot remains stationary or moves at constant speed the robot accelerates the robots mass increases

Explanation:

According to Newton's first law, when the net force on an object is zero (two equal and opposite forces cancel each other out), an object at rest remains at rest (stationary) and an object in motion remains in motion with a constant velocity (constant speed in a straight line). Mass is an inherent property of an object and is not affected by forces acting on it. Also, acceleration occurs when there is a non - zero net force (\(F = ma\), if \(F = 0\), then \(a=0\)). Changing direction would imply a change in velocity (since velocity is a vector) and thus an acceleration, which is not the case here as net force is zero.

Answer:

The robot remains stationary or moves at constant speed
