The FCI was designed to assess student understanding of the Newtonian concepts of force.

In this example, the field equation is simply a statement of the Newtonian concept that centripetal force is equal to gravitational force for circular orbits.

Need for Speed 3, published by Electronic Arts, doesn't quite conform to Newtonian concepts of momentum and gravity, but it does take a subtler approach.

For example, I think it will be agreed that the Newtonian concept of mass has a more precise meaning than the concept of democracy, say.

In both its mathematics and its fundamental ideas, this new physics seemed to contradict the Newtonian concept of particle interactions.

In the 20th century, the Newtonian concepts of absolute time and space were challenged by relativity.

The Newtonian concept of gravitational mass rests on Newton's law of gravitation.

Einstein rejected the Newtonian concept and identified t as the fourth coordinate of a space-time four-vector.

Today's physics students keep thinking of physics concepts in Aristotlean terms, despite being taught only Newtonian concepts.

The next step is the Newtonian concept of force and inertia.
