∙ 11y agoA train's brakes start exerting force on the wheels when the brake system is activated by the engineer using either compressed air (pneumatic brakes) or electricity (electric brakes). The force applied by the brakes creates friction between the brake pads and the wheels, which slows down the train.
Friction between the brake pads and the train wheels is the force that ultimately stops the train when the brakes are applied. The brake pads create friction by pressing against the rotating wheels, converting the kinetic energy of the train into heat energy as they slow down the train.
It takes more effort to stop a car that does not have power brakes, although its rare to see a car without power brakes any longer. In either case, the literal answer to your question is yes it does increase the force applied to the brakes. Two feet are stronger than one. More force on the pedal translates to more force on the brake pads.
Gravity
When a force is applied to an object but does not cause the object to move, it means that the force is balanced by an equal and opposite force, resulting in a state of equilibrium. This can happen when the applied force is opposed by friction, gravity, or some other force preventing movement.
Static friction occurs when a force is applied to an object but does not cause it to move. This frictional force acts in the opposite direction of the applied force and prevents the object from moving until the force exceeds the maximum static frictional force.
An increase in applied force will cause the object to accelerate.
It depends on the decelerating force applied by the brakes.
An unbalanced force will cause an acceleration and a change in motion.
Liquids in hydraulic brakes help to stop an automobile by creating pressure and moving a set of pistons to generate force. This force is applied outward and causes friction that stops the automobile.
It is possible to do no work on an object if the force applied is perpendicular to the direction of motion of the object. In such a case, the force may cause the object to change direction but not cause any displacement in the direction of the force. Work is only done when there is displacement in the direction of the force applied.
When force increases, the force applied is greater, resulting in a stronger push or pull on an object. This can cause the object to accelerate or deform depending on the nature of the force and the object's characteristics.
