According to Newton's second law of motion, if a rigid body of unchanging mass is observed accelerating, what must be happening?

• A force was once applied but is now not being applied.

• The mass must be changing.

• Unbalanced forces act "all crazy!!!" on an object.

• A force is being applied to the mass.
