the friction acting on something moving through air

• air resistance

• fluid

• free-body diagram

• inversely

• newts 2nd law

any liquid, gas, material that cannot sustain a tangential, or shearing force when at rest undergoes a continuous change in shape to subjected stress

• terminal speed/ velocity

• pressure

• fluid

• pascal

• free-body diagram

a diagram showing all the forces acting on an object

• inversely

• free-body diagram

• newts 2nd law

• pascal

• terminal speed/velocity

two values change in opposite directions; when the value of one quantity goes up with respect to down in other or vice versa

• air resistance

• fluid

• pascal

• inversely

• pressure

the acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the object

• newts 2nd law

• inversely

• free-body diagram

• pascal

• pressure

the unit of pressure or stress in the international system of units (SI)

• inversely

• pascal

• pressure

• fluid

• free-body diagram

the amount of force per unit of area; the force applied perpendicular to the surface of an object per unit of area over which that force is distributed ex: force/area of application

• terminal speed/velocity

• newts 2nd law

• pressure

• pascal

• fluid

the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration; air drag force is equal to the force of gravity

ex: direction and acceleration

• terminal speed/velocity

• newts 2nd law

• inversely

• air resistance

• presure
