• change the speed of an object
• change the direction of motion of an object
• change both the speed and direction of motion of an object

Answer 2

The acceleration that the resultant force produces on an object depends on
-the size of the resultant force 
-the mass of an object
Remember:
Force= Mass*Acceleration
