[10h] Name this effect that causes an upward force on a spinning object. This effect is what causes a cricket ball to swing in the air.
ANSWER: Magnus effect
[10e] The Magnus effect occurs because this force acts on a spinning object. Airfoils produce this force, which opposes gravity and keeps airplanes up.
ANSWER: lift [or aerodynamic force]
[10m] This equation is used to calculate the lift on an airplane’s wings. This equation relates changes in pressure to height and fluid velocity.
ANSWER: Bernoulli’s equation [or Bernoulli’s principle]
