How can tension lead to failure in materials? Excessive tension can cause materials to elongate and reach a breaking point. 5 What causes material fatigue? Repeated application of stress causes material fatigue, leading to weakening and eventual failure. 4 What does shear strain mean? Shear strain...

but the two words don't mean the same thing. The difference between mass and weight is that mass is the amount ofmatterin a material, while weight is a measure of how the force of gravity acts upon that mass.1
Rheology is concerned with the question 'How does a material respond to a force?'. The basic equation in words is ÀÁ Force ¼ property ´ ðmeasure of responseÞ Physical scientists refer to forces acting on materials in terms of stresses, or force per unit area. The response ...
Bleh. Raw fresh figs do NOT taste like fig newtons minus the cake part, just FYI. Some people, lots of people in fact, love them, but I am not one of them. So I thought I hated figs. But as with most things in life (I swear to you, I promise on all that is good and holy...

(according to Oxford: "extreme or alarming importance; seriousness") or gravitas ("dignity, seriousness or solemnity of manner") take on additional significance. That said, when someone refers to the "gravity of a situation" a physicist might still need clarification: Do they mean in ...
The metric units for force are newtons, those for distance are meters and those for work are newton-meters, or joules. Energy is the capacity for doing work, and it is also expressed in joules. Kinetic and Potential Energy An object in motion possesses its energy of movement, which is equ...
weight is properly reported using units of kg·m/s2or Newtons (N). However, since everything on Earth is subject to about the same gravity, we usually drop the "g" part of the equation and just report weight in the same units as mass. It's not correct, but it doesn't cause proble...
