An object accelerates because a force acts on it.
F=ma
Force is equal to the mass of an object times acceleration
The larger the mass, the greater the force needed to accelerate it
An object at rest will stay at rest unless acted upon by an unbalanced force.
An object in motion will stay in motion unless acted upon by an unbalanced force.

Two forces are applied to a 17 kg box, as shown. The box is on a smooth surface.Which statement best describes the acceleration of the box?
A) The box accelerates at 1.0 m/s2 to the right because the net force is 17 N to the right.
B) The box accelerates at 1.9 m/s2 to the right because the greater force is to the right.
C) The box accelerates at 3.0 m/s2 because the combined forces cause the box to accelerate.
D) The box does not accelerate, because neither force is large enough to move the box.
