Friction causes wastage of energy
WebAug 28, 2024 · The correct answer is It does not cause wastage of energy.. Friction is the force that resists the relative motion of solid surfaces, fluid layers, and material elements … WebFriction can be defined as the force that resists the relative motion of solid surfaces, fluids, or elements that collide or slide against each other. Its effect would cause the object in motion to slow down. If the friction is increased, more energy is needed by the object to keep its momentum hence it will slow down.

WebSep 19, 2024 · Friction is a force that opposes the motion of an object. For example, when you are sliding a box along a surface, there is a friction force that resists the motion. The friction force is caused by the contact between the molecules of the external surfaces of the object and the molecules of the surface where the object is sliding over. WebMay 31, 2024 · Friction produces a lot of heat in various parts of the machinery and this leads to wastage of energy as heat. Opposes motion, hence more energy is needed to overcome friction. ... Friction causes wear and tear in machinery parts and also cause wastage of electricity and energy. Friction causes moving objects to stop or slow down.
WebApr 14, 2024 · The main drawback of friction stir welding (FSW) dissimilar metals is the formation of intermetallic compounds (IMCs), which are brittle and affect the strength of the joint. The formation of these compounds is inevitable due to their low enthalpy of formation; however, their emergence is an indication of metallurgical bonding between dissimilar … WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s.
