Newton's first law

Add object that is at rest will remain at rest and an object that is moving will get to you to move in a straight line with constant speed if and only if the net force acting on the object is zero

Force

A push or a pull

Interaction pair

a set of two forces that are in opposite directions, have equal magnitudes, and act on different objects

Tension

a force exerted by any segment of a rope or string on an adjoining segment

Net force

the vector sum of two or more forces acting on an object

Equilibrium

A state of balance, net force on an object is zero

Drag force

a force exerted by a fluid on an object moving through the fluid

Newton's Second Law

The acceleration of an object is directly proportional to the net force on it and inversely proportional to its mass, F=ma

apparent weight

The support force acting on an object

Contact force

a push or pull on one object by another that is touching it

Newton's Third Law

For every action there is an equal and opposite reaction

Normal field

A perpendicular contact force exerted by surface or another object

Inertia

The tendency of an object to resist a change in motion

free body diagram

a diagram showing all the forces acting on an object

terminal velocity

The constant velocity of a falling object which is with the drag force equals the gravitational force

weightlessness

an object's apparent weight of zero that results when there are no contact forces pushing up on the object

gravitational field

Vector quantity that relates objects mass to the gravitational force it experiences at a given location

Weight

The gravitational force experienced by an object
