Answer:
Friction is defined as Friction provides traction that is needed to walk without slipping. Friction is useful in most cases, however, they also provide a great measure of opposition to the motion. About 20 per cent of the engine power of automobiles is consumed in overcoming frictional forces in the moving parts. In the next section, let us go through some of these factors.

Answer:
zero
The resultant force on the car is zero. a runner at their top speed experiences the same air resistance as their thrust. an object falling at terminal velocity experiences the same air resistance as its weight.
