Osama Malik 8 years, 2 months ago

Spring constant is the ratio of restoring force per unit increase in length. K=-f/x where f is restoring force and x is increase in length of spring. Negative sign because force is in opposite direction. Its SI unit is N/m.

ANSWER

why work done on a system is negative (in physics) and positive (in chemistry)?

Posted by Ravi Pal 8 years, 3 months ago

CBSE > Class 11 > Physics

2 answers

Ritika Thakur 8 years, 3 months ago

Because in chemistry if work done on the system it means chemical reactions is not done by the system.But in case of physics if work done by the system it means piston expands and its volume increases so work is positive and its reverse is negative.
