the initial velocity of the object. the forces acting on the object. the direction of movement of the object. the change in kinetic energy of the object.
I gave my students this multiple choice question: The rate of acceleration of an object is determined by the mass of the object and

Only one answer is correct among these 4 choices:
- the initial velocity of the object.
- the forces acting on the object.
- the direction of movement of the object.
- the change in kinetic energy of the object.

Could you tell me which one is correct?

the forces acting on the object.
