Newtons first law

If the resultant force of all the forces is zero (0N), the object is either stationary or it moves along a straight line at a constant speed

Slide 7 - Slide

Air resistance

F^{​ r, a ​ ​} = \frac{​ 1 ​ ​}{​ 2 ​} C^{​ d ​ ​} \cdot ρ \cdot A \cdot v^{​ 2 ​ ​}

F_r,a: Force, resistance, air resistance (n)
C: resistance coefficient (no unit)
ρ: The density of air (or whatever medium the object is traveling through) (kg/m³)
A: area of the object (m²)
v: the speed of object (m/s)
