Drag is generated when an object moves through a fluid, like air or water. It is the resistance force that acts opposite to the object's motion. Drag is caused by the friction and differences in pressure between the object and the surrounding fluid, slowing down the object's movement.

What are the three forces acting on a glider in flight?
Thrust generated by the glider's propulsion system, lift generated by the glider's wings, and drag acting in the opposite direction to the glider's motion.
What force counteracts drag?
Thrust is the force that counteracts drag. Thrust is generated by engines, propellers, or other propulsion systems to overcome the resistance caused by drag and move an object forward.
How does a helicopter achieve drag?
A helicopter experiences drag through air resistance as it moves through the atmosphere. The main sources of drag in a helicopter are profile drag from its overall shape and skin friction from the airflow over its surface. Additionally, rotor tip vortices and induced drag generated by the rotor system contribute to overall drag.
The parachute slows the rocket down by increasing aerodynamic circle?
The parachute creates drag that opposes the rocket's motion, slowing it down. This drag force is generated as the parachute catches the air and creates turbulence, reducing the rocket's speed.
Is lift needed to overcome drag?
Yes, lift is needed to overcome drag in order for an aircraft to maintain level flight. Lift is the force generated by the wings that counteracts the force of drag acting in the opposite direction. This balance allows the aircraft to move forward through the air.

What are the forces of flight?
The four forces that act on an airplane in Flight are Lift (upward generated by the wings), weight (Down generated by gravity, Thrust (forward generated by the engines), and drag (essentially backward generated by the resistance of the aircraft to the atmosphere).

If you drag something and there is friction what will happen?
Answer: 1. There will be heat produced 2. the surfaces will be eroded Answer: 3. A force opposite the direction of movement is generated.
How do rotocopters work. weight. lift. drag. thrust?
Rotocopters work by spinning rotor blades to generate lift. The weight of the rotocopter is supported by this lift force, which must be greater than the weight for the rotocopter to stay airborne. Drag is generated as the rotocopter moves through the air, which must be overcome by thrust generated by the rotor blades to maintain forward motion.
What forces act on an object while in flight?
While in flight, the main forces acting on an object are lift, weight (or gravity), thrust, and drag. Lift is generated by the wings to support the weight of the object, while thrust is provided by an engine or propeller to propel the object forward. Drag is the resistance generated by the object moving through the air, opposing its forward motion.
What types of force can an airfoil exert?
An airfoil can exert lift, drag, and thrust forces. Lift force is generated perpendicular to the airflow and is essential for providing the upward force needed for an aircraft to stay aloft. Drag force acts opposite to the direction of motion and resists the aircraft's movement. Thrust force is generated by the aircraft's engines and propels the aircraft forward.
How does drag affect the motion on a car?
Drag is a force that opposes the motion of a car, generated by air resistance. It acts in the opposite direction to the car's movement, slowing it down and requiring more energy to overcome at higher speeds. A streamlined design can help reduce drag and improve the car's performance and fuel efficiency.
