• The seesaw moves up and down around its central fulcrum.
• In this experiment, measure the weight applied and the distance from the fulcrum.

Primarily used in mechanical descriptions to describe a fixed point supporting something that turns or balances, and in a metaphorical sense to describe a crucial, changing point.

• The dancer made a graceful turn around her pivot foot.
• The company's strategy had to pivot due to market changes.

Best used to describe the joint or flexible point that allows a door, gate, or lid to swing open or shut.

Use in general contexts to describe the middle point or part of something, often indicating importance or focus.

• The shopping mall is at the center of the city.
• She stood at the center of the stage during her performance.

Used often in a mechanical or technical sense, referring to the pivot point or central support about which a lever turns or balances.

• The seesaw balances perfectly at the fulcrum
• The crankshaft acts as a fulcrum in the engine

Used more broadly to indicate the middle point or the most important area of something. It is neutral and can apply to places, objects, or abstract concepts.
