This image depicts a collision analysis between two objects, highlighting the forces and momentum involved. A large mass (M) and a small mass (m) collide, with initial momentum vectors shown moving toward one another. At the moment of impact, force vectors (F) act between them, resulting in final momentum vectors pointing away in different directions. The illustration includes colorful impact effects to emphasize the interaction, and features the equation impulse (FΔt) equals change in momentum (Δp) at the bottom, explaining the physical principles of the collision.
