 # Motion and Force MCQs

For your better entry test preparation and better Physics MCQs preparation, in this section, we are going to post Motion and Force MCQs. In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity which includes the beginning of moving from a state of rest to accelerate.

A force can also be described intuitively as a push or a pull. Force cause the object moving from a state of rest.
