The director used full-motion videos to recreate the city's past in a compelling visual narrative.

The museum's archive contains rare full motion videos from the 1990s that researchers study.

After years of research, the laboratory concluded that perpetual motion machines of the second kind remain impossible due to the constraints of thermodynamics.

Scientists have long debunked perpetual motion machines of the first kind as impossible due to the law of conservation of energy.

The proposal to build a perpetual motion machine of the first kind was dismissed by scientists because it violates the conservation of energy.

Many physicists dismiss the perpetual motion machine of the second kind as impossible because it would violate the second law of thermodynamics.

The fox lay motionless in the tall grass as the hikers passed by, unaware of its presence.

She stood motionlessly at the edge of the pier, watching the fog swallow the city.

The motionlessness of the statue gave the courtyard an eerie sense of suspended time.

The clock's motionwork needed lubrication after years of neglect.
