the direction of the friction force on the car is in the same direction to the VELOCITY of the car.

Explanation:

When the brakes are applied on a moving car then the speed of the car reduces slowly. The slowing of speed and the stopping of car takes a certain time which is proportional to the force applied by the brakes.

The brakes when applied to the moving part on the axle of the vehicle be it either drum or the disc offers the resistance to the rotation of the wheels in the form of friction.

As we know that friction always acts in a direction opposite to the relative motion between the two surfaces. So does here in this case the friction of brakes acts in a direction tangentially opposite to the rotation at the point of application of the brakes.

Similarly, the friction between the tyres and the road acts in a direction tangentially opposite to the direction of the relative motion between the surfaces i.e. the tyres move backwards relative to the road surface and hence the friction acts in the forward direction and is in the same direction as the motion of the car.

same direction

Explanation:

When a car is moving on the road frictional force act opposite the direction of the velocity of the vehicle.

But when you apply the brake the wheel will have the tendency to stop but friction will oppose.

The friction force starts acting in the direction of motion.

Hence, when you apply the brake on the moving car the direction of the friction will be in the same direction of the velocity of the car.

Is a vector quantity that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

both the fifth and fourteenth amendments of the united states contain a due process clause. while the fifth amendment describes a legal obligation of the federal government to not deprived of life, liberty or property without due process of law, the fourteenth amendment applies the same obligation to the states to guarantee that all of the states provide fair procedures as well.
