Force vs. Strength — What's the Difference?
By Tayyaba Rehman — Updated on October 23, 2023
"Force" refers to an external push or pull on an object, while "strength" denotes the ability or capacity to withstand or exert force, often related to physical or mental power.

Key Differences
"Force" and "strength" are terms frequently used in various contexts, ranging from physics to personal character traits. When discussing "force", one is typically referring to an external influence, be it a push, a pull, or some kind of coercion. It's an agent that causes change or movement in a particular direction, much like the force applied to move a stationary object.
"Strength", in contrast, often embodies the innate ability or power of an entity. While force may act externally, strength is a measure of internal capability. For instance, in the realm of materials, the strength of a metal signifies how much force it can endure before deforming.
Distinguishing between "force" and "strength" can sometimes be subtle, especially when discussing intangible aspects. For example, someone might employ force in an argument by being aggressive, while another might show strength through patience and resilience. Such examples underscore that while "force" implies a direct action, "strength" highlights the inherent capability or endurance.
In the physical world, the difference is perhaps clearer. When a weightlifter lifts a heavy weight, the muscles exert force on the weight, but the amount they can lift is determined by their strength. Therefore, while the concepts of "force" and "strength" often intertwine, their essence diverges, with force being the action or influence and strength being the inherent capacity.

Common Curiosities
Are force and strength synonyms?
While related, they are not exact synonyms. Force refers to an external push or pull, while strength denotes the capacity to resist or exert force.
Is strength always physical?
No, strength can also refer to mental or moral fortitude.
Can strength be negative?
In general language, strength is viewed positively, but contextually, an attribute might be a "strength" to one and not to another.
Is every force in physics related to movement?
Not necessarily. Forces can also be static, like the force of friction preventing movement.
How is strength measured in materials?
It can be measured in terms like tensile strength, compressive strength, etc., depending on the force applied.
Can force be a measure of strength?
Not directly. Force is the exerted action, while strength is the capacity to exert or withstand that action.
Can an argument be both forceful and strong?
Yes. An argument can be forceful in its delivery and strong in its content or reasoning.
Can force exist without motion?
Yes. Objects can experience force without any observable motion, like a book resting on a table experiencing gravitational force.
Can strength be developed?
Yes, both physical and mental strength can be developed and improved over time.
How do muscles show both force and strength?
Muscles exert force to move objects, and the amount they can move or resist moving reflects their strength.
Can strength be temporary?
Yes, strength can fluctuate based on factors like health, mental state, or external conditions.
Can something be strong without being hard?
Yes. For instance, a material can have tensile strength (resist pulling forces) without being hard.
Is force always visible?
No. Forces like gravity or magnetic forces aren't visible but can be observed through their effects.
Is force always physical?
While often physical, force can also refer to abstract concepts like force of will or forceful arguments.
What's a common unit of force in physics?
The Newton (N) is a common unit used to measure force.
