Newton’s Second Law
a = acceleration (m/s2)
F = force (Newton – N)
m = mass (kg)
w = weight
m = mass in kg
g = acceleration due to gravity (9.8 m/s2)
Since the car is traveling at a constant speed, it is not accelerating. This means that the force of the road on the tires is equal to the air resistance and we have balanced forces.
