Fundamental Engineering Concepts Quiz

According to Newton's first law of motion, what happens to a body at rest or traveling straight forward at a constant speed?

• It accelerates in the direction of an external force

• It stays in that state unless a force is applied

• It deforms due to the applied force

• It rotates around an axis
