Which law of science is NOT involved in a fall?

The law of science that is not involved in a fall is related to the concept of "size." While friction, momentum, and gravity are all fundamental forces or principles that play a role in how objects fall and interact with their environment, size does not have a direct influence on the mechanics of a fall in terms of the fundamental laws of physics.

Friction is important as it can either help to slow down a fall or prevent slipping when a surface is involved. Momentum describes the motion of a falling object and how its speed and mass combine to affect how it falls. Gravity is the force that pulls objects toward the Earth, causing them to fall. Size, however, refers to the dimensions or volume of an object and does not correlate directly with the forces at play during a fall. Therefore, size is not a scientific law that influences the dynamics of falling objects in the same way the other factors do.
