What drives the forces that shape our world?
Quick fact
A force is an interaction that can change an object's motion, direction, or shape.
Why this is interesting
Everything from falling objects to orbiting planets is controlled by forces interacting with matter.

Understanding What drives the forces that shape our world?
Forces are pushes or pulls caused by interactions such as gravity, electromagnetism, and contact between objects. Newton's laws describe how forces affect motion.
A deeper explanation
Modern physics describes forces through fundamental interactions: gravity, electromagnetism, and the strong and weak nuclear forces. These interactions determine how matter behaves at every scale.
