Answer;

It can cause an object to accelerate.

It can cause an object to start moving.

It can cause an object to change directions.

Explanation;

-Objects can only accelerate if there are forces on the object.

The net force is the vector sum of all the forces exerted on an object. the direction of the total acceleration vector points in the same direction as the net force vector.

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. According to Newton, an object will only accelerate if there is a net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.

A force is a push or a pull that is capable of changing the velocity of a mass. Forces are measured in “Newtons” or “N”, in honor of Sir Isaac Newton. According to Mr. Newton, an object will only accelerate if there is “net force” acting upon it. A net force is the sum of all forces acting on an object. A net force is capable of accelerating a mass. For instance, if the wheels of a car push it forward with 5 Newtons and drag is 3 Newtons, the net force is 2 Newtons, forward. Motion to the right is positive. Motion to the left is negative.
