Drag and lift are forces that act on an object moving through a fluid, and are crucial in determining its motion and overall behavior. These forces are particularly significant for objects moving through a fluid, such as air or water.
Drag is a force that opposes the direction of motion and tends to slow down an object moving through a fluid. It is typically proportional to the velocity of the object and the size of the object itself.
Lift is a force that acts upward and helps to push an object moving through a fluid. It is typically proportional to the weight of the object and the velocity of the object.
The total force acting on an object moving through a fluid is the vector sum of drag and lift. The direction of the net force will also depend on the direction of motion.
Examples:
A flying airplane experiences both drag and lift as it moves through the air.
A ball rolling down a hill experiences drag.
A swimmer in a swimming pool experiences lift due to the water's buoyancy
