Match each of the forces with the clue to determining its presence. 1-Always present when two surfaces are in contact 2-When an object is stretched or compressed 3-When two surfaces are in contact and only when the objects are not moving with respect to each other 4-When two surfaces are in contact and only when the objects are moving with respect to each other Always present 5-When an object is being pulled without being stretched which one i need to choose ? 1- normal force/ 2- kinetic friction/ 3- gravity always / elastic force/ static frictionExplanation / Answer
1-Always present when two surfaces are in contact : gravity always, normal force... 2-When an object is stretched or compressed : gravity always, elastic force... 3-When two surfaces are in contact and only when the objects are not moving with respect to each other: gravity always, normal force,static friction.. 4-When two surfaces are in contact and only when the objects are moving with respect to each other : gravity always,normal forcem kinetic friction... 5-When an object is being pulled without being stretched which one i need to choose: gravity always, kinetic friction...
