which factor best determines the direction that an object will move

The best factor that determines the direction an object will move in is the net force acting on the object. The net force is the vector sum of all the forces acting on the object. If the net force is non-zero, the object will accelerate in the direction of the net force. However, if the net force is zero, the object will remain at rest or continue moving with a constant velocity in the same direction. Therefore, the net force is the crucial factor that determines the direction an object will move in.

the options are. 1 the Earth's gravity 2 the direction and magnitude of force applied. 3 how hard the object is thrown. 4 the direction of the object closest to it

Among the given options, the factor that best determines the direction that an object will move is: 2) the direction and magnitude of force applied. The direction and magnitude of the force applied to an object determine the resulting net force, which in turn determines the direction in which the object will move.
