Bats achieve lift by creating low-pressure zones above their wings during the upstroke and a high-pressure zone during the downstroke. This pressure difference generates lift. They produce thrust by flapping their wings, propelling themselves forward. By combining these mechanisms, bats are able to fly efficiently and maneuver gracefully.

2 forces that help overcome gravity?
The two forces that help overcome gravity are lift and thrust. Lift is generated by the wings of an aircraft, providing an upward force that counteracts gravity, while thrust is produced by engines to propel the aircraft forward, allowing it to achieve lift and ultimately overcome gravity.
How do lift thrust drag and gravity work together to achieve flight?
Lift is generated by the wings to counteract gravity and keep the aircraft airborne. Thrust is provided by the engines to overcome drag, which is the force that resists the aircraft's forward motion. Together, lift and thrust work against gravity and drag to keep the aircraft in a state of controlled flight.
What are The four forces acting on an airplane in flight are?
The four forces acting on an airplane in flight are lift, weight (or gravity), thrust, and drag. Lift is generated by the wings and opposes the force of gravity. Thrust is produced by the engines and overcomes the force of drag, which is caused by air resistance.
How does a helicopter achieve thrust?
A helicopter achieves thrust through its main rotor blades. The rotation of the blades creates a pressure difference, causing air to move downward and generating lift. By controlling the pitch and speed of the rotor blades, the helicopter can adjust the amount of thrust produced.
How does the lift thrust drag and gravity affect a helicopter?
Thrust from the helicopter's rotor blades generates lift, which enables the helicopter to overcome gravity and stay airborne. Drag acts as a resistance opposing the helicopter's forward movement, requiring additional thrust to maintain speed. Gravity affects the helicopter by constantly pulling it downward, necessitating continuous lift to counteract and remain in the air.
