On What Principle Does The Braking System In The Car Work?
The braking system in the car works on the frictional force. A brake system or braking system is a means by which energy is converted into heat by using the friction of a brake pad on a brake drum.
This process slows or stops the rotation of an object, such as a wheel or rotor, through the use of friction between moving surfaces that are in contact with each other.
If an object moves faster than the speed at which it can stop safely (for example, if it's going 100 km/h when it brakes), some kinetic energy will be lost as heat and sound.
The braked vehicle rotates at less than the actual speed until friction dissipates all released energy to heat and sound, effectively bringing the vehicle to rest.
What Is Frictional Force?
"Friction" is the force in which one surface or object rubs against another to resist motion. The force of friction between two bodies is proportional to the pressure on each body and inversely proportional to the materials' "coefficient of friction," μ," (also called "static coefficient of friction," μ).
Types of Frictional force:
Static friction
The force of friction acts between surfaces while at rest relative to one another.
When a tiny amount of force is applied, the size of the static force in the opposite direction is identical. When the force rises, static friction reaches its maximum value.
Sliding friction
It is the resistance caused when two objects slide against one another.
Fluid friction
It is described as the friction between fluid layers when they move relative to one another.
Rolling friction
This is the weakest form of friction and is described as the force that resists the motion of a ball or wheel.
How frictional force works in breaking the system of the car?
The braking system in the car work on the frictional force. The friction force is applied to the brake pads by a friction material that contacts the brake drum that spins with the wheel.
When the car slows down or stops, a mechanism applies pressure to the brake pad to force against the spinning drum, creating friction between them and slowing down or stopping a wheel.
The energy of motion is converted into heat and sound due to this rubbing action. So, the braking system in a car work on the Frictional Force principle.
