Question

what is strength in physics

Answer 1

Capacity to do something is strength
It could refer to any number of factors, from tensile strength to shear strength.I normally refer to “raw strength” as a synonym for maximum force production
For example if electric force is experienced at a place,then there exists electric field strength. if gravitational force is experienced at a place, then there exists gravitational field strength. it’s denoted by E. it’s direction is along the direction of force.field strength at a place can be defined as the force experienced per unit charge or mass depending on the nature of force.
