Here's a breakdown:
* Compression: A type of stress that occurs when forces push or press inward on a material. Think of squeezing a sponge.
* Forces: The push or pull that can change the motion of an object.
* Ends of an object: This means the forces are acting on opposite sides of the object, pushing towards the center.
Example: A bridge supporting a heavy load experiences compression forces as the weight of the load pushes down on the bridge deck, causing the bridge supports to push back inward.
