Here's a breakdown:
* Gravity: A force that pulls objects towards each other. On Earth, gravity pulls everything towards the planet's center.
* Lift: An upward force that opposes gravity. It's generated by the movement of a fluid (like air or water) around an object.
Here are some examples of lift:
* Airplanes: The shape of an airplane wing creates a difference in air pressure above and below the wing, generating lift.
* Helicopters: The spinning blades of a helicopter create a downward flow of air, pushing the helicopter upward.
* Birds: Birds use their wings to create lift, allowing them to fly.
So, while gravity pulls things down, lift is the force that helps things stay up or even move upward.
