Which two phrases describe a situation that will cause a stationary object to start moving? A. a net force greater than 0
B. unbalanced forces
C. a net force equal to 0
D. balanced forces

A .a net force greater than zero

B. Unbalanced Force

Explanation:

A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .

B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .
