How do friction work
WebEngineers need to understand the force of friction so that they can design safe roads, tires, cars and brakes. Engineers also try to reduce the force of friction between moving mechanical parts so that they will last longer. When a car's tires start to turn, the friction between the road and the tires make the car begin to move forward. WebFriction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down. The amount of friction …

WebJun 18, 2024 · Friction is a force that resists sliding motion between contacting surfaces. A bike, for example, has many instances of friction. The brake pads and the wheel rims have … WebFriction. Friction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between surfaces and always in a direction that opposes motion or attempted motion of the systems relative to each other. If two surfaces are in contact and moving ...
WebFeb 20, 2011 · Since friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned.
