Gravitational Field
A Region Of Space In Which A Mass Experiences A Force Of Gravity, Described By Newton Law Of Gravitation.

Weight
The Force Of Gravity Acting On An Object Mass, Related To Gravitational Field Strength.

Mass
A Measure Of The Amount Of Matter In An Object, Influencing Its Resistance To Changes In Motion According To Newton Second Law.

Newtons Third Law
A Law Stating That For Every Force There Is An Equal And Opposite Force, Forming Action Reaction Pairs.

Newtons Second Law
A Fundamental Law Stating That The Acceleration Of An Object Is Proportional To The Net Force Acting On It And Inversely Proportional To Its Mass.

Newtons First Law
A Principle Of Classical Mechanics Stating That An Object In Motion Stays In Motion And An Object At Rest Stays At Rest Unless Acted Upon By A Net Force.

Force
A Push Or Pull That Causes A Change In Motion, Described In Newton Second Law.

Motion
A Change In Position Of An Object Over Time, Described In Classical Mechanics Using Quantities Such As Velocity And Acceleration.

Classical Mechanics
A Branch Of Physics That Describes The Motion Of Objects Under The Influence Of Forces, Based On Laws Such As Newton First Law.

Physics
The Scientific Study Of Matter, Energy, And The Fundamental Forces Of Nature, Including Concepts Such As Motion And Force.
