In what direction does an object move when affected by an unbalanced force? 2. large force= force= 3. large mass= mass=

We can answer the question by looking at Newton's second law:

or, equivalently,

where a is the acceleration given to an object of mass m, to which is applied a force F.

So:
1) When the force F is large, the acceleration of the object is large. When the force is small, the acceleration will be small.
2) On the contrary, when the object has a large mass m, the acceleration will be small. When the mass of the object is small, the acceleration will be larger.
