Physics stress definition
WebbStress Definition It is a type of resisting force that acts on a body per unit area. When this resisting force is exerted by the body to avoid deformation, is known as stress. The force that acts on the body is called load or force. WebbStress kan vara både bra och dåligt. Stress kan ge dig extra energi ett tag och göra att du kan få mer gjort. Men stress kan också få dig att må dåligt. Det är okej med stress, men inte hela tiden. Det är okej att ha det stressigt ett tag, det är inte farligt. Men hjärnan och resten av kroppen klarar inte hur mycket stress som helst.
