chang sees the following formula on a website about newtons second law. $a = \\frac{\\sigma f}{m}$ what does the symbol $\\sigma f$ in the formula indicate that chang needs to do? he needs to find the net force acting on the object in a direction. he needs to use only forces acting in the direction of motion. he needs to combine the horizontal and vertical forces. he needs to multiply the horizontal and vertical forces.

Answer

Answer:

He needs to find the net force acting on the object in a direction.

Brief Explanations:

In Newton's second - law formula $a=\frac{\sum F}{m}$, $\sum F$ represents the net force (the vector sum of all forces) acting on an object. It accounts for all forces in all directions to determine the acceleration of the object.
