What is drag force?
Think about forces acting against motion.
Define lift force.
Consider forces involved in flight.
What does drag force oppose?
Think about objects moving in fluid.
True or False: Lift force acts parallel to the fluid direction.
Consider how planes lift off.
A drone weighs 1.5 kg and has a wing span of 1.2 m. Calculate the lift force required for the drone to take off considering a lift coefficient of 1.2 at a velocity of 8 m/s.
Use the lift equation for your calculations.
An object has a drag coefficient of 0.1 and a cross-sectional area of 0.5 m². Calculate the drag force it experiences at a velocity of 15 m/s in air (density = 1.225 kg/m³).
Make sure to plug values accurately into the drag equation.
