Conservation of linear momentum is another great conservation law of physics.
Collisions, such as between billiard or pool balls, illustrate this law very nicely: the

ELEVATOR PHYSICS
What are the forces at play on our bodies during the ride?
During the upward acceleration?
Normal force exceeds weight, and the body feels heavy because the floor of
the elevator is pushing us up harder than usual.

thing from the mind. Although yes, technically they are two different things, the mind
often controls what the body does. Our bodies almost always react to what mind
