Lift
Lift explained in an easy to understand way:
Imagine you're trying to open a stubborn jar lid that just won't budge. Just like how the jar lid comes off when you manage to create more force on one side than the resistance on the other, lift occurs when there's a difference in pressure above and below an object. In both cases, it's about overcoming resistance: for the jar, the difference in force helps twist the lid off, and for lift, the difference in air pressure causes the object to rise.
Practice Version
Lift: An upward force on an object due to differences in pressure. Lift. Lift is the force that enables airplanes to rise into the air and stay aloft by creating a pressure difference above and below their wings.
