Penguins cannot fly due to gravity being greater than the lift force their wings can generate.
Jeremy explained that a penguin cannot fly because...
The correct answer is D. the force of gravity is greater than the lift force that their wings can generate. Penguins are flightless birds due to their body structure and the gravitational force being higher than the lift force needed for flight.
When comparing the forces acting on penguins, the gravitational force pulling them down exceeds the lift force their wings can generate to counteract gravity and achieve flight.
