Question

if the motion diagram of an object shows acceleration of an object, the free - body diagram of the object should have an unbalanced force
o that is perpendicular to the acceleration.
o in the direction of the acceleration.
o in the opposite direction of the acceleration.

Explanation:

According to Newton's second law of motion, \( F = ma \). The net force (\( F \)) and acceleration (\( a \)) are vectors. The direction of the net force (unbalanced force) is the same as the direction of the acceleration.

Answer:

in the direction of the acceleration.
