Breaks are not something people take the time to think about. Even if they are fundamental to the vehicles many people use every day. The functionality of breaks is contributed to physics and engineers ability to understand that physics. There is a lot going on when people press on the brake pedal in their car. The most basic principle of brake pads is in fact friction. This friction is the thing that transfers the energy of the car moving forward to heat energy. Brakes also use pressure as a leverage when pressing the brake pedal. There is also, momentum and even sound in the physics brakes. All of which are physical properties. Brakes have multiple pieces that all work together to help a car come to a stop, or slow down. The main parts …show more content…
It allows extra small ridges and bumps that catch on the brake disk. When the ridges and bumps catch on each other they pull in the opposite direction that the wheel is moving. When brake pads are pressed tighter against brake disks more friction is created. This happens because more, and larger ridges, are now able to pull the wheel in the opposite direction it wants to move. The fairly large surface area of brake pads also helps create friction. A large area means there is more material to create friction. More friction means quicker and easier stopping …show more content…
The force of pressing on the brake pedal in a car is transferred through multiple parts until it presses on the brake pads. This takes a lot of leverage on the part of the brake system. That is what hydrolic brakes are for. There is a small amount of brake fluid in a cylinder with no air. When a person presses down on the brake pedal it compresses the fluid. This creates a large amount of pressure (Q&A). The pressure then pushes on brake cylinder which pushes on the brake piston. Both of which causes the brake pads to press against the brake disk. There is also a feeling of pressure against the driver 's foot as the pedal pushes back with the same amount of force that is pushed on it. Though it does not take much force to compress the brake fluid, the liquid in the cylinder. This means that the brake pedal is easy to push down and do not have to move far to
