Assuming that the brakes are not "dragging" they start exerting force on the wheels when they are applied by the engineer.

What type of force are you exerting when you lie on a bed?
Compression.APEX :)
Which forces are acting when you stretch a spring?
The force you are exerting to stretch it, and the restoring force of the spring.
What type of force are you exerting when your stomp your foot on the ground?
Compression.
Is a carpenter hammering a nail an example of exerting force?
yes
Why do keep moving forward when you slam on the brakes on your bicycle?
Because when you brake, the brakes stop the wheels from moving. But that doesn't stop the bike from moving. It means that the speed/force/velocity at which you were traveling was forceful enough to override the brakes. So basically, you're sliding.
What makes toy car stop rolling on the floor?
The force of gavity on car exerts friction on the wheels and axle that eventually stop the car from exerting forward force.
How do automobile brakes work?
Learn how brakes work, about the physics of braking and see a simple brake system. ... How does your car transmit the force from your leg to its wheels Disc brakes are the most common brakes found on a car's front wheels, and they're often on all four. This is the part of the brake system that does the actual work.
What are the components of a car brake?
There are six components of a car brake. It starts with the pedal that the driver presses. Most of the other parts (combo valve, booster, master cylinder) are meant to transmit the action into force, until finally the wheels are reached. Here, drum brakes and disc brakes are used to apply force to the wheels and force them to stop turning.
Is riding a bike newtons seond law?
yes it can. the reason why is the force the wheels are exerting is pushing them foeward. ok that sucked look read a book dont check internet
If only external force can change the velocity of a body how can the internal force of the brakes bring a car to rest?
It is not the force of the brakes that is stopping the car but rather external force of friction between tires and the road. Notice that no matter what the force at the brakes is, the car won't stop if there is no friction there(ie. the road is slippery). This is an excellent question. Consider the NASA space shuttle. It has brakes, yet the brakes work only on the ground - only while the shuttle is landing. Why? In space, the brakes have nothing to react against. So, as the questioner suspects, the internal forces of the brakes alone are not sufficient to change the velocity of the space shuttle. But once the shuttle lands, and is rolling down the runway, applying the brakes creates friction between the wheels and the runway. And it is the external force of the runway pushing back against the braking wheels that causes the shuttle to slow down.

What is proportionate force?
Exerting force in a porportional manner, not using too much or too little force.
Which forces are acting when you stretch a spring?
The force you are exerting to stretch it, and the restoring force of the spring.
