define air resistance
5 answers
Air resistance, also known as drag, is the force exerted by air on a moving object. This force opposes the motion of the object through the air and can reduce its speed or increase the amount of energy required to maintain its motion. Air resistance is influenced by factors such as the shape and size of the object, the speed at which it is moving, and the density of the air.
in simple terms
Air resistance is the force that pushes against objects as they move through the air, making it harder for them to move quickly or maintain their speed.
does air resistance act in the same direction or opposite direction of gravity?
Air resistance acts in the opposite direction of an object's motion through the air. In most cases, this means that air resistance is acting in the opposite direction of gravity, which is pulling the object downward. So, when an object is falling through the air, air resistance is pushing against its downward motion.
